The most widely used search engine is in the test phases of launching an upgrade code-named "Google Caffeine." Designed to provide more comprehensive and accurate search results, it is critical to know exactly how this new Google engine will affect your website's rank.
Most of the changes will influence the way Google indexes pages. This means that how it stores relevant website information on its servers may change the order in which site results are displayed. Adjustments may also include the ability to better recognize synonyms.
"Google Caffeine" is still in the pre-beta test. You can see how your website stacks up in the new Google by visiting the developer’s beta version.
