No amount of search engine optimization efforts can guarantee you top position in the search results, especially if you fail to look at your site with the critical eyes of a search engine spider. Unless you use a search engine simulator, there is no other way to determine how the search engines regard your site.
Generally all crawler-based search engines operate on the same lines. They crawl through your website when directed to it from some other location (back link) and index each individual page of your website under different keyword categories. The indexed information is stored in a huge database from where it is periodically used for comparison, relevancy check and retrieval based on the string of search query provided. The page results for different search engines vary widely, depending on the unique search algorithm of each different search engine.
When you optimize your website for different search engines, what you are actually trying to do is to critically look at your website from the view point of the search engine and device ways to improve your site s visibility to that particular search engine. For this, you would need to know what it is that exactly interests a search engine and what it is that the search engine dislikes such as linking to bad neighborhood, keyword stuffing, backlink bombing, overuse of flash sites, use of Java script and images for navigation, etc.
Here are a few points to provide you with better insight into what search engines like to see in your site
Search engines cannot read flash, Javascript, images or frames. So, use them very sparsely. Never use Javascript or images for navigation. Always go for text instead because all crawler based search engines can index text best. Back links are important to point to your website from other websites. So, aim at obtaining large number of one-way high-quality inbound links from relevant and related websites. However, you can be penalized for backlink bombing, so, maintain a reasonable ratio of inbound and outbound links. Optimum use of important keyword phrases is imperative and you should maintain an optimum keyword density throughout the web page. However, your website can be penalized for keyword stuffing if your keyword density exceeds the prescribed limit.
Strategic placement of keyword phrases (in your URLs, domain names, web page title, file names, headlines, description and keyword metatags, etc) is also important. Well-written and crisp metatags containing keywords is another criteria which is liked by many search engines.
