Themes...The Next Evolution of Search Engine Optimization
Theme has become crucial for search engine optimization and search engine positioning for long-term success. Search engines now use themes as a technique to index a site. Themes help the search engines to provide new and better ways to serve up relevant results while still maintaining a manageable database.
Content maintains its king position. So sites have started putting in as much content as possible. Many times this results in content duplication. Search engines have implemented filters to get rid of duplicate content and invisible text. Even the importance of META tags as well as many other tags has been reduced.
The new search engine algorithms though count click-thru, added link popularity and link quality to judge a site still lag behind giving rise to the new concept of "themes". Theme indexing considers the content as well as theme of the page and site, and link popularity.
Today many search engines have incorporated themes into their ranking systems necessitating webmasters to understand it thoroughly and use them to his or her advantage.
