Basic Understanding of Search Engine Optimization

Two words are most important in SEO: relevance and importance. Relevance means that whether the content is what the search engine users are looking for. Importance means that whether the content provides valuable information.

Most important factors influencing search engine ranking results:
Different search engines have different criteria or algorithm. For instance, Yahoo said “Inbound links and content are important.” Bing said”Keywords should be contained in the content and the size of the page should be at right size.” Google said “WebPages should be for users not for me. So give your page a correct title and don’t put too many links on one page.” Of course, these are only some principles and their searching algorithms are always changing, at least from time to time.

How to fully understand how a search engine works? You can ask a search engine engineer who develop it or you can design an experiment to test it and figure it out by yourself. All the trouble shooting strategies are same. Every time you change one factor and then see what is the result. If you get the result you want, obviously the last factor that you have changed is the reason for the problem. So when designing experiment to study search engine, you can build several similar websites and each website has only one factor different from the rest of others. This may sounds easy, but when you really do it, it will have a lot of work involved. But fortunately someone else has already done this type of experiments and what you need to do is just to follow their guidance or observe carefully what they did on their own site.

Then you may ask: how can I who knows the secret of seo? It is easy. Run a simple search with some hot keywords in major search engines and those sites on the 1st page of the search results are your candidates. Do a thorough study on those sites, and you will learn a lot from them.
