Introduction to SEM (Search Engine Marketing)
Search engines have become an integrated part of our lives. In today's world, 'being online' is not an option. In US alone, around 7 billion searches are being made every month. Travel, finance, entertainment, education, health or ecommerce, search engines are being used to find information, products and services.

Search Engine Marketing or SEM is the process of marketing a website via search engines. SEM strategies primarily consist of Search Engine Optimization (SEO) and Pay Per Click (PPC) advertising.

SEO is the process of improving natural or organic rankings on search engines. Search engines rank websites based on variety of parameters and each search engine has its own algorithm to rank different swebites. However, one common and most important ranking parameter is a site's credibility which is determined by the quality and quantity of other sites which link to it. PPC is a type of internet advertising in which the advertiser pays an agreed amount to a search engine for every click a visitor makes on the advertisement. It is also referred to as Cost Per Click (CPC), Paid Placement and Search Engine Advertising.

SEM Industry

The SEM industry grew significantly in 2006 as compared to 2005 when it was less than $6 billion in size. According to the same research, while SEO is the most popular form of SEM, it accounted for around 10% of the total spending. However, Paid Advertising accounted for over 85% of the total SEM spending in 2006.

Over the last few years, the importance and the acceptance of SEM has grown significantly. According to a survey by SEMPO, of all the respondents, more than 50% said that Senior Management at their companies are 'very involved' in their SEM program. Sales and Brand awareness were the two major objectives behind all SEM programs.

Growth in the SEM industry has created a strong demand for experienced and talented Search Engine Marketing professionals. This demand is expected to grow even faster in the coming years with lots of new opportunities for existing and budding Search Engine Marketers.

The SEM industry offers various kinds of job roles for its professionals. Given that the industry is still evolving, these job roles are also changing and new roles are being created with new initiatives. For instance, online PR (Public Relations) has gained significant growth over the last year and so is the need for PR writers and marketers.

What Is RSS

RSS is a format for syndicating news and the content of news-like sites, including major news sites like Wired, news-oriented community sites like Slashdot, and personal weblogs. But it's not just for news. Pretty much anything that can be broken down into discrete items can be syndicated via RSS: the "recent changes" page of a wiki, a changelog of CVS checkins, even the revision history of a book. Once information about each item is in RSS format, an RSS-aware program can check the feed for changes and react to the changes in an appropriate way.

RSS-aware programs called news aggregators are popular in the weblogging community. Many weblogs make content available in RSS. A news aggregator can help you keep up with all your favorite weblogs by checking their RSS feeds and displaying new items from each of them

Inbound Link

Also known as back link, backward link, or backlinks, inbound links are all of the links on other websites that direct the users who click on them to your site. Inbound links can significantly improve your site’s search rankings, particularly if they contain Anchor Text keywords relevant to your site and are located on sites with high Page Rank.

out bound link

A link that points away from your website..

keyword density,keyword prominence,back links

1)Keyword density :The density of keyword affects the ranking of your page. The higher the keyword density the higher is your rank so one should always include a 30-40 word paragraph containing key-word rich content, thus increasing the keyword density.

2)Keyword prominence :The keywords you have chosen should appear in title, Meta and H tags with some occurrence in the body also. So you should not define Google without putting the word Google in the body of the definition. This means H and P tags should go hand shaking with each other.

3)Page rank and back links: The more site links to your site better is the page rank of your site and more relevant your site is. Google also takes into consideration the words [or Anchor text] that appear in your back links

4)Content:Some say that the Content of your site is the king, but for me it’s actually the crown which the webmaster wears if his site has the right content. Build the content and users will be interested

How to generate quality inbound Links?

Quality Content - There are all kinds of link generating systems out there but in my opinion the best way to get links to your blog is to write quality content that people will want to read. You can solicit links with others or sign up for different link building programs or even buy text links on other sites but the cheapest and probably safest approach is to build inbound links in a natural organic way as others link to your quality content.
Notify Relevant Bloggers of your content - Whilst I don’t advocate spamming other bloggers and asking for links - I would recommend that if you write a quality post on a topic that you know will interest another blogger that it might be worth shooting them a short and polite email letting them know of your post. Don’t be offended if they don’t link up, but you might just find that they do and that in addition to the direct traffic that the link generates that it helps build your own page rank in the search engines (more on letting other bloggers know of your posts here).
Directories - Another way to generating inbound links is to submit your links to directories. I know of webmasters who swear by the benefits of such a strategy - the first thing that they do when starting a new site is to do the rounds of directories - submitting links to key pages with appropriate keywords in the links. There are loads of directories out there - many of which offer a free submission. Ari Paparo has compiled a list of blog directories that you might want to start with.
Inter-link your Blogs - Increasingly bloggers are starting or joining blog networks to enjoy the benefits of multiple sites and writers working together. One of the advantages of networks of sites is that they usually link to one another. In doing so you have complete control over how your sites are linked to from multiple domains. It is worth noting that you should be careful with this approach - if all your sites are hosted on the one server many think that Search Engines will work out what you’re doing and the impact will be lessened.
Buy Links - Many professional web masters have a budget to purchase links from other highly ranked and and relevant sites. I won’t go into this too much here but you might like to read more about it in my recent post On Buying Text Links. update: I’d encourage anyone wanting to buy links to think very carefully about this. Google have been cracking down on sites that use this practice. They can’t catch everyone but some have been caught and seem to have been penalized for doing it.
Swap Links - Similarly many bloggers swap links with other bloggers. Sometimes this happens pretty naturally (you see someone linking to you so you link back) but in many cases the links are strategic ones and formally arranged between site owners. I get daily requests for such reciprocal links (I rarely act on them). Whilst there is some benefit in such link swapping I would again advise caution here as many SEO experts believe that the search engines have methods for tracking such strategies and devaluing the links. Some try to get around this by doing indirect or triangulated links. ie instead of site A and B doign a direct swap they involve other sites. So A links to C in exchange for D (also owned by C) linking to B (also owned by A) - makes your head hurt doesn’t it!?! There are also a variety of systems around that say they’ll take care of such interlinking for you - I know many who use system. Personally I tend to avoid such schemes and have a policy of linking to sites I think are valuable to my readers. If they link back then so be it.

what is one way link

One-way links are links that point to your site from other sites which are not linked to from your site.
These types of links send a very powerful message to all of the major the search engines. In short it lets them know that your website is extremely valuable, very interesting or useful to owners and readers of other sites that they want to tell their audience about it.

One-way links are great to have because they help to increase your link popularity - the number of pages that link directly to your site. Search engines, especially Google, place a ton of importance on link popularity when ranking your site in their results.

You should also also garner direct traffic to your site from people who travel to your sites through links on other sites.

Most links to your site are good, but when at all possible you should aim for links on sites that are topically related to your site and its content.

During 2005, Matt Cutts of Google staed on his blog that Google does not reward sites that abuse reciprocal linking. You should take notice of this warning and try to make sure that as many of your links as possible are one-way links.

Ways to get one-way links
Make your website interesting and useful to your target reading audience.
Submit your site to DMOZ.org, in the appropriate category.
Write useful and informative articles then submit them to article directories online.
Hunt for blogs that complement yours and engage their readers in discussion then ask them to publish your articles or link to them.
Post brief, useful hints to industry specific blogs and discussion boards for the same reason.
Publish articles on pages within your site and invite other websites related to your content to publish them on their websites, with a link pointing back to your article.
Write testimonials.
Participate helpfully and without expectation of direct gain in related forums. Read the forum rules and protocols first, or you risk making a bad or damaging impression.
Give away free ebooks and white papers that have links to your site.
Get listed in online business directories.
Create a blog and submit it to the major blog directories.
These few tips should get you on your way to building a web of one-way links to your site. There are many more ways to go about getting one-way links to your site. The one thing you need to remember is that linking and getting one-way links to your site is an ongoing process and should be incorporated as part of your daily schedule

What is Social Media Optimization

What are Social Media Websites?
First, what is social media? The quintessential social media site is myspace. Myspace is completely user generated, in other words, all the content comes not from some mega corporation, but the users themselves. Other examples of social media sites are Facebook, Digg, del.icio.us, and Squidoo. Basically, a social media site creates a community of people with similar interests, and allows them
to network and communicate on any given topic.

How Can I Advertise With Social Media Sites?
So how can a business use social media for their advantage? Banner ads? Text ads? – Not a chance. The very reason social networking sites exist is because their users trust each other rather than advertisers. They are skeptical of traditional media, and would rather read a review from a group member than the hyperbole of a copy-writer. So can you still use social media to advertise? Absolutely, but you must go about the process much differently.

Give If You Want to Get
In order to get your name out with social networking, you must become one of the community rather than an advertiser to the community. Create a profile on myspace and link up with people of similar interests. If you have a well branded product or a faithful customer base, encourage your myspace members to spread the word. One of my clients posts html banner code on their myspace and encourages members to copy and paste it into their own profiles.

Become involved in sites like Digg and StumbleUpon. Once you've developed a recognized profile, people will pay attention to what you post. The more buzz your posts create, the more traffic and inbound links your site will receive.

The Bottom Line
Don’t try to exploit social media by shamelessly promoting your product. The most effective way to succeed in this area is become involved in a relevant community and wait for the users to embrace your product or service. This concept may seem foreign to most business owners marketing their business, however it’s absolutely essential and is the only way to succeed with social media marketing.

Google XML Sitemap

Google Sitemaps are XML files that list the URLs available on a site. The aim is to help site owners notify search engines about the URLs on a website that are available for indexing. Webmasters can include information about each URL, such as when it was last updated and its importance in the context of the site. You should try to make all pages on your site easily accessible to search engines without the use of google sitemaps. But there are situations when your site might benefit from Sitemaps Protocol like for instance if your site is built in rich AJAX or Flash, or if you have a large database driven site that isn’t well linked.

FTP

FTP (File Transfer Protocol) is a technology that allows computer users to transfer files from a local to remote hosts. Most websites are updated or made using a FTP upload system. There are many fee programs that provide FTP technology. Some webpage editors have a FTP system build into them, like Dreamweaver. SSH is also a good protocol to transfer files.

External link

An External link is simply a link to a different website. By carefull with linking to external websites, because Google might punish sites linking to bad neighborhoods or sites with a bad reputation. Quite the opposite is true as well, sites linking to so-called authority sites might by respected more by the Spiders. If you’re not sure about linking or if you do not want to pas on PageRank you could always use the html attrinute rel=’nofollow’:

anchor text

By using this a spider does not follow the link and can not punish your website or pass on PageRank.

Mediapartners-Google/2.1

This a Bot or Spider used by google to index pages serving Adsense Ads. It indexes a page so the Adsense Publishers Program knows what a page is about, so they can provide related advertisement.

Dynamic Site

A dynamic site uses a database to store it’s content. It delivers it’s content dynamically by parsing variables passed on by the users browser, thus showing the content the user requested. Dynamic sites are easy to maintain and usually a CMS is incorporated. A CMS or Control Management System allows the webmaster to add or change content without uploading html pages. Most large sites, forums and blogs are dynamic Sites.

Cross Linking

Cross linking was a good way to boost Pagerank in the past. By exchanging links with other websites, called reciprocal links, PageRank could be increased greatly in the past. The search engines caught up and didn’t weigh reciprocal links that heavy as one way links.
After this happened people started cross linking, where links were exchanged via links from a different site a site was linking to. This way a triangular linking structure was accomplished. For search engines it’s harder to discover this scheme, but they are catching up, and cross linking will not be as lucrative in the future.

5steps increase your page rank

Google Page rank is based on back links. Back links are Links pointing to your website from another website. The more back links you have the higher your PR will be.

1. Join forums, forums are a great way to achieve links to your website. In most forums you are allowed to have a signature and in your signature you can put a link to your website. But another important note to look on is making sure the forum is somewhat related to your website. You will still get credit if it's not, but if it's related to your website than you will be accomplishing two tasks at once.

You will be advertising for your website (bringing in targeted traffic) You will also be building your websites presence.

Your websites presence is very important to your survival. The more people see, or hear about your website the more credibility you will have and this increases your chances of having these visitors come back and possibly become leads.

2. Submit to search engine directories. Search engine directories are a good way to get a free link to your website. They also increase your chances at being listed higher on popular search engines like Google, and overture.

Most search engine directories allow you to submit to their website for free. This will allow you to increase your web presence by being listed on another search engine, and it will also be a free link.

Remember the more links you have the higher your PR will be

3. Using ezine ads (or newsletters). Creating an ezine will probably be the most beneficial step you can take to increasing your web presence. When you create an ezine you will be able to keep visitors coming back to your website for more by using signatures and giving special deals.

Ezine's will also allow you to increase your back links. By creating an ezine you can submit your information about your ezine to an ezine directory. This directory will than link to your website(thus giving you a free link).

4. Creating and publishing articles. Articles are an easy source of generating new traffic. You can include your signature in your article. This will bring in more traffic from article submission directories.

Your signature usually consists of 4 to 8 lines. Usually the first line would be the title of the website that you are trying to advertise. The last line would be the link to the website and the lines in between these would be a sales pitch to draw your viewers into your website.

5. Links from related websites. Gaining links from related websites can be one of the most frustrating tasks you can attempt

Link Exchange Tips

1.Exchange links with websites that will bring you targeted traffic. Targeted traffic means visitors and/or customers that will be interested in your products or services.

2. Keep your link title brief and free of long sentences.

3. Try to keep your link description brief (aim for 200 characters or less).

4. Do not capitalize all letters in your link title or description.

5. Do not give the webmaster a deadline on when they should reciprocate. Webmasters are very busy people and it may take from 1 to 60 days or more. Be patient and in the long run you will receive more quality link partners!

6. Never remove a link partner from your site once they have agreed to exchange links with you and placed your link on their site.

7. Do not request link exchanges from sites that are unrelated to your website. For example, if you have a candle website, don't exchange links with a pharmaceutical website. This will not benefit your customers or visitors and the search engines may penalize your website for this.

8. Let the webmaster know that you have indeed visited their site and explain to them why a reciprocal link exchange with your website would be beneficial.

9. Be sure that your link pages are search engine friendly. Link pages are easier indexed if they have no more than 25 links per page.

10. Complete your website before requesting reciprocal link exchanges. Most webmasters will not link to a site where most of the pages are "under construction".

11. Do not give misleading information in your link exchange request. Most webmasters are not going to believe it and your request will most likely be ignored. For example, don't claim that your site receives 100,000 unique visitors a day unless your site really receives that many.

12. It is best to categorize your link partners. For example, you might want to have a home and garden page, a home improvement page, a candles page, etc. This is a much better way or organizing your links for both your visitors and your link partners. If you just have one huge page of links in no order, most webmasters will not approve your link exchange request.

13. Make sure your links page is linked and visible from your home page.

14. If your site is family friendly, do not add link partners that offer services or products that are not family friendly.

15. Be aware of free-for-all link programs and link farms. These are sites that basically offer nothing but unrelated links and end up collecting and sharing your email address, which results in a lot of unwanted SPAM in your inbox.

The above tips are only a few suggestions on how to build a successful linking campaign. Most importantly, be patient and take your time to find quality link partners that will add a valuable resource and bring targeted traffic to your website.

Importance of sitemaps

here are many SEO tips and tricks that help in optimizing a site but one of those, the importance of which is sometimes underestimated is sitemaps. Sitemaps, as the name implies, are just a map of your site - i.e. on one single page you show the structure of your site, its sections, the links between them, etc. Sitemaps make navigating your site easier and having an updated sitemap on your site is good both for your users and for search engines. Sitemaps are an important way of communication with search engines. While in robots.txt you tell search engines which parts of your site to exclude from indexing, in your site map you tell search engines where you'd like them to go.

Sitemaps are not a novelty. They have always been part of best Web design practices but with the adoption of sitemaps by search engines, now they become even more important. However, it is necessary to make a clarification that if you are interested in sitemaps mainly from a SEO point of view, you can't go on with the conventional sitemap only (though currently Yahoo! and MSN still keep to the standard html format). For instance, Google Sitemaps uses a special (XML) format that is different from the ordinary html sitemap for human visitors.

One might ask why two sitemaps are necessary. The answer is obvious - one is for humans, the other is for spiders (for now mainly Googlebot but it is reasonable to expect that other crawlers will join the club shortly). In that relation it is necessary to clarify that having two sitemaps is not regarded as duplicate content. In 'Introduction to Sitemaps', Google explicitly states that using a sitemap will never lead to penalty for your site.

Why Use a Sitemap

Using sitemaps has many benefits, not only easier navigation and better visibility by search engines. Sitemaps offer the opportunity to inform search engines immediately about any changes on your site. Of course, you cannot expect that search engines will rush right away to index your changed pages but certainly the changes will be indexed faster, compared to when you don't have a sitemap.

Also, when you have a sitemap and submit it to the search engines, you rely less on external links that will bring search engines to your site. Sitemaps can even help with messy internal links - for instance if you by accident have broken internal links or orphaned pages that cannot be reached in other way (though there is no doubt that it is much better to fix your errors than rely on a sitemap).

If your site is new, or if you have a significant number of new (or recently updated pages), then using a sitemap can be vital to your success. Although you can still go without a sitemap, it is likely that soon sitemaps will become the standard way of submitting a site to search engines. Though it is certain that spiders will continue to index the Web and sitemaps will not make the standard crawling procedures obsolete, it is logical to say that the importance of sitemaps will continue to increase.

Sitemaps also help in classifying your site content, though search engines are by no means obliged to classify a page as belonging to a particular category or as matching a particular keyword only because you have told them so.

BackLinks

Backlinks are incoming links to a website or web page. Backlinks enable you to keep track of other pages on the web that link to your website. The number of backlinks is an indication of the popularity or importance of that website or page. In basic link terminology, a backlink is any link received by a website (web page, directory, website, or top level domain) from another website. Backlinks are also called incoming links, inbound links, inlinks, and inward links.

Google Page Rank

here are many theories about page rank I am trying to give the best information about page ranks to help you to increase page rank of your web pages.

Google was the first search engine company to patent the system of taking into account inbound links, this algorithm was named as page rank. Page rank is estimated separately for each web pages and is determined by page rank- Citation, of other pages referring to it. Page rank is also regarded as the possible frequency of visits to a web page.
The Page Rank of a specified web page is thus defined as the probability that a visitor or a user may visit the web page.

It is assumed that the user starts viewing the websites from some random web pages, then the visitor or user follows the links to other web resources. There is always a possibility that the user may leave a web site with out following any outbound links and start viewing documents from a random webpage. The page rank algorithm estimates the probability of this event as 0.15 at each step. The probability that our users or visitors continue surfing by following one of the links available on the current web page is therefore 0.85, assuming that all links are equal in this case. If the user or visitor continues surfing indefinitely, popular web pages will be visited many more times than the less popular web pages. The sum of probabilities for all existing web pages is exactly one because the user or visitor is assumed to be visiting at least one Internet Web page at any given moment.

We can see Google page rank number between zero and ten on the Google tool bar. We can determine the Page Rank value for any web page with the help of the Google Tool Bar that shows a Page Rank value with in the range from 0 to 10.

Usually now a days Page Rank is not used directly in the Google algorithm. Since pure Page Rank characterizes only the number and the quality of inbound links to a Web Site, it completely ignores the text of links and the information content of referring pages. These factors are important in page ranking and they are taken into account in later versions of the search engine algorithm.

how to start seo dynamic website

Search Engine Optimization tips for websites

Search Engine Optimization (SEO) methods for dynamic websites; like - ecommerce, blogs, forums etc

Few weeks ago, one of my client asked me how he should advice his web designer to optimize his dynamic (ecommerce) website as his designer was about to start designing a new website. As usual I created and shared a Google document and wrote the basic SEO methods - that’s it. He was happy!

Now, the question is what’s the difference between static website search engine optimization and dynamic website search engine optimization?

Literally, there is no difference. Just our thoughts for dynamic website makes the difference. OK - how? For some people think dynamic website is this, dynamic website is that - but every day we are creating, using thousands of dynamic websites without having this in our mind. I believe - almost 100% webmasters have their own blogs - may be they are using Wordpress or Blogspot or something else. Don’t you think these applications are dynamic websites? Of course they are! So if you know SEO methods about Wordpress, blogspot, typepad etc - that means you are already aware of search engine optimization!

hi friends my friend recently launched website:www.templatescup.com free templates

static and dynamic

There are two types of URLs: Dynamic URLs and Static URLs.

When we search a database driven website a dynamic URL is displayed. Dynamic web page is basically only a template to display the result of the database query. Instead of changing information in the HTML code the data is changed in the database. Dynamic URL is generated from specific query to a site's database.

Search engines generally like to list the WebPages that are unique

In Static URLs the contents of the web page remains same unless there is change in html code. Static URLs help the end users to understand the web page easier, when a user sees a URL in a search engine query that matches title and description they click on the URL Than one that doesn’t make sense to them.

Static URLs are ranked better in search engine results pages, and they are indexed more quickly than dynamic URLs. Static URL doesn’t have a variable string, it looks like this.

http://www.srihithatechnologies.com/seo.html

When we use dynamic Urls there is a risk with search engines as they don’t like them. Dynamic websites like e-commerce stores, forums, and sites utilizing content management systems and blogs or any data base driven website have most risk of losing search engine positioning due to dynamic URLs

Urls generated for the content by a dynamic websites looks like this:

http://www.andhrahospitalsinfo.com/hospitals.php?cat=Allopathy&district= Hyderabad&city= Hyderabad&area=Ameer%20pet

http://www.andhrahospitalsinfo.com/hospitals.php?cat=Allopathy&district= Hyderabad&city=Hyderabad&area=Banjara%20Hills

http://www.andhrahospitalsinfo.com/hospitals.php?cat=Allopathy&district= Hyderabad&city=Hyderabad&area=Charminar

For example, let's look at below 3 URLs:

All these three URLs point three different pages, but if the search engine purges the information after the first offending character, the question mark (?), now all the 3 web pages look the same:

http://www.andhrahospitalsinfo.com/hospitals.php http://www.andhrahospitalsinfo.com/hospitals.php http://www.andhrahospitalsinfo.com/hospitals.php

so in the above case as there are no unique pages the duplicate URLs wont be indexed.
Dynamic web pages generally do not have any keywords in the Url. It is very important to have keyword rich URLs. It is good to place highly relevant keywords in the domain names or on the url pages.
