The Caffeine update represents a major restructuring of the Google search engine processes. Now that caffeine is officially released, webmasters around the globe have been able to chime in with their opinions and statistics.
First, even though speculation was that Google caffeine would represent significant changes to the search engine algorithm this turned out to be as reported by Google upon the release of caffeine false. While slight changes to the algorithm did take place as they always have throughout the years, the greatest degree of change in the Google search engine turned out to be in its method more than its structure. Prior to June 10, 2010 Google gathered and cached website information in levels of predetermined importance. These levels were given names by IT web professionals such as the Google main index, Google supplemental index, and Google omitted results. No doubt other levels existed unnamed and unnoticed.
The “new” Google no longer waits several weeks to stockpile sufficient snapshots of web sites before placing that data into its index. Instead the collection of Googlebots circling the Internet globe now continually report in with website data from an almost random sampling process. It is believed that the sampling process then determines the depth of Googlebots crawling (scanning).
What will come as a surprise to many people previously uninformed as to Google’s robot/spider functions is that for several years now what’s doing exactly this same thing had been in existence from Google. Those were referred to as the “freshbots” and page results from these Google crawlers has always been reported in an index within a few days of scanning any particular pages.
So what does this mean in terms of a 60 day report on caffeine? Basically it appears that caffeine allows Google to constantly add sites to its index while attempting to keep cached older websites and their inner pages.
A comparison would be that of a paperboy randomly tossing newspapers to homes around the city as opposed to pedaling his or her bicycle along a specified and limited route.
