Search Engine Optimization

search engine optimization, the process of increasing the amount of visitors to a Web site by ranking high in the search results of a search engine. The higher a Web site ranks in the results of a search, the greater the chance that that site will be visited by a user. It is common practice for Internet users to not click through pages and pages of search results, so where a site ranks in a search is essential for directing more traffic toward the site. SEO helps to ensure that a site is accessible to a search engine and improves the chances that the site will be found by the search engine.

How Web Search Engines Work?
Search engines are the key to finding specific information on the vast expanse of the World Wide Web. Without sophisticated search engines, it would be virtually impossible to locate anything on the Web without knowing a specific URL. But do you know how search engines work? And do you know what makes some search engines more effective than others? When people use the term search engine in relation to the Web, they are usually referring to the actual search forms that searches through databases of HTML documents, initially gathered by a robot. There are basically three types of search engines: Those that are powered by robots (called crawlers; ants or spiders) and those that are powered by human submissions; and those that are a hybrid of the two. Crawler-based search engines are those that use automated software agents (called crawlers) that visit a Web site, read the information on the actual site, read the site's meta tags and also follow the links that the site connects to performing indexing on all linked Web sites as well. The crawler returns all that information back to a central depository, where the data is indexed. The crawler will periodically return to the sites to check for any information that has changed. The frequency with which this happens is determined by the administrators of the search engine.
Human-powered search engines rely on humans to submit information that is subsequently indexed and catalogued. Only information that is submitted is put into the index.

In both cases, when you query a search engine to locate information, you're actually searching through the index that the search engine has created —you are not actually searching the Web. These indices are giant databases of information that is collected and stored and subsequently searched. This explains why sometimes a search on a commercial search engine, such as Yahoo! or Google, will return results that are, in fact, dead links. Since the search results are based on the index, if the index hasn't been updated since a Web page became invalid the search engine treats the page as still an active link even though it no longer is. It will remain that way until the index is updated. So why will the same search on different search engines produce different results? Part of the answer to that question is because not all indices are going to be exactly the same. It depends on what the spiders find or what the humans submitted. But more important, not every search engine uses the same algorithm to search through the indices. The algorithm is what the search engines use to determine the relevance of the information in the index to what the user is searching for. One of the elements that a search engine algorithm scans for is the frequency and location of keywords on a Web page. Those with higher frequency are typically considered more relevant. But search engine technology is becoming sophisticated in its attempt to discourage what is known as keyword stuffing, or spamdexing. Another common element that algorithms analyze is the way that pages link to other pages in the Web. By analyzing how pages link to each other, an engine can both determine what a page is about (if the keywords of the linked pages are similar to the keywords on the original page) and whether that page is considered "important" and deserving of a boost in ranking. Just as the technology is becoming increasingly sophisticated to ignore keyword stuffing, it is also becoming more savvy to Web masters who build artificial links into their sites in order to build an artificial ranking.

How to Survive the Google Pagerank

Go Bold
Just as women love bold suitors, so do search engines. Start highlighting keywords on each page with the tag to increase search relevance. Search engines are attracted to words contained in the H1 and B tags. Just don’t go wild- two bold words per page is enough.

Go Deeper
Having other sites drill deep into your web at various locations tells google that ‘hey, this guy has varied useful content’. It’s poor SEO strategy to acquire links just to link to the homepage. The search engines may ultimately discount those links.

Go foreign
Why focus on North America? You can take your business to UK, Pakistan, India, Indonesia, and Hongkong! Start creating pages for lucrative markets and submit to their local directories. This ensures multiple streams of revenue.

Fire Up Newsletters
Provide articles to publishers like ezinearticles. The links breathe for many years in their archives and funnel backlinks to your site.

Go Big
Image links are good, but text links are more appreciated. If your site is full of image links, have your webmaster place the text links first because that’s what google looks for. Subsequent links are often discounted.

Multiple Partners
Create different domains on varying IPs that talk about similar subjects. The reason is that Google only lists one domain page per search result. Imagine if you owned ten domains that came up for the same search result? You’ll be seducing more curious searchers. Another tip: search engine consulting firms recommend varying the keywords used on these domains just to minimize looking spammy

Article Exchanges
You’ve heard of reciprocal link exchanges. Text link purchases. One way backlink purchases. Try them, and it’s like getting herpes on the net. Google blacklists you and your worth is downgraded. But article exchages are different. Whip up an article, upload to Ezinearcticles and before you know it- wham! Dozens of sites publish your article and bring fawning admirers to your door.

Shun Unvaried Anchor Text If 1000 sites links to you with the appellation “Gimme Money”, Google starts to squint and dig deeper, “Smells like automated filthy spam, methinks.” Avoid the search engine ban by varying the anchor text. Dance under different names and you’ll flirt more grandly with search engines.

Expose Your Glory With a Site map Your visitors reach the honeypot more rapidly when you have a structured sitemap that links to every major page. Keep the map on a location easily accessible so you keep the action flowing. Google bots flirt with sitemaps too and often births detailed search results. So keep it search engine friendly.
