The Google Dance

Just how does Google update its entire index? This is a to a certain extent broad question, but we will make clear each and every step that Google takes every month to make certain its database is the most pertinent and of the maximum quality.

Quite a good number of people and companies understand that, in order to get hold of the best Google rankings in the early hours in their search engine optimization (SEO) campaigns, it is significant to take all the essential steps before plus carefully plan ahead. In respect to non-fee search engine submissions, Google turn out to be one of the very few left. It's also one of the most primitive to include it in its database.

As of November 18 2003, it is far and wide estimated that the worldwide Google database consists of in excess of 3.6 Billion pages. And that is simply a fraction of all available web sites, as some of them are not open toward Google, ie: those sites are not to be trip by a search crawler or else spider.

For instance it often is in real life, with all this come a bunch of risks as well as potential difficulty that website owners, webmasters as well as Search Engine Optimization (SEO's) professionals need to cautiously assess while in the initial production plus pre-launch stage of the marketing program. While most experts be in agreement that Google spiders (crawls before as well as after certain phases, they are not sure at which exact point in the month they will do their spidering and lastly update their whole database.

The Famous Google Dance

If you think you require to write an email to get request to an annual dance at the Google headquarters, the GooglePlex, you might want to carry on reading this important chapter on just precisely how Google's database as well as search robot technology operates. While the Google monthly bring up to date cycle is fairly well documented, over the past year this cycle (now affectionally called the "Google Dance") has turn out to be less and less of a pattern as well as more of a giant step in darkness for the majority webmasters and site owners who earnestly await all monthly updates.

Each "dance" starts on with Google making a most important, deep crawl. Let's call it Crawl A. What it does is it spiders the entire web- over 3.4 Billion pages eventually count. Google uses in excess of 15,000 inexpensive PC's (in fact, conventional desktop computers) spread all over the world situated in different data centers. When it sends Googlebot (or DeepBot) out to spider the present sites within its database, as well as to find new websites that have recently been launched on the web. at the start, once Google has completed this Crawl A, efficiently catching all of these web pages for its next update, there will be a second update afterwards, approximately two weeks later.

Google will then bring up to date its whole database, screening the new results on www2.google.com plus www3.google.com. All along for the period of this update, the results are frequently rapidly switched between the primary database along with the second and third database. As acknowledged earlier, because Google uses over 15,000 servers, the majority people in all areas of the world are generally seeing very different search results, until the majority of the update in finally completed.

The "Google Dance" will continue intended for another few days, but more often than not no longer than a week in duration (if not there are problems and/or main algorithm changes done by Google for instance the April 2003 update).
