Caffeine Update by Google

Caffeine update which was announced by Google on August 10, 2009 had become one of the most important updates in the search engine’s history.

Google had released a ‘Developer Preview’ before the launch and gave SEO professionals and developers’ early access to Caffeine so they could report issue, if found.

On June 8 of 2010, it finally became public.

What is Caffeine Update?

Caffeine was a new web indexing system that allowed Google to crawl and store data far more efficiently. With Caffeine, Google gained the capability to crawl, collect data, and add it to their index in seconds. Thus, fresher information was available across a wider range of sites.

How Caffeine Worked?

Basically in their old indexing system, pages and content types were put into a category based on the perceived freshness requirements. Different crawlers were sent out, some looking for changes and others re-indexing changed pages. If a site was in the fresh category it was crawled by different bots that would add the content to the index quickly, but for most sites, their content would be re-indexed every couple weeks.

What changes it brought?

Because the update itself revolved around Google’s ability to index content and content changes rapidly, there were all sorts of blog posts and articles claiming that updating content frequently yielded an SEO strategy.

This update had nothing to do with adjusting ranking signals. If fresher content yielded better rankings; this was due to other algorithms, not Caffeine.

It may have been made possible by the Caffeine Update, but the update itself didn’t impact results in this way.

Reason behind launching Caffeine

The reason behind the need of caffeine was, the Initial Google indexing system was designed in 1998. During that time there were 2.4 million websites and 188 million people on the internet worldwide. The ratio showed a major gain.  By 2009, there were 100 times more websites at 238 million and almost 1.8 billion people trying to get to them with no end in sight to the growth in either. There was also increase in online videos, graphics, maps and other data. The old index lacked to fulfill the new demand. Thus Caffeine was launched.

To understand the concept better take the example of your wardrobe. When you are single, one wardrobe is enough to put all your cloths but when a spouse enters, the space begins to fall short.  The space becomes even scarcer when a new born arrives. So instead of struggling everyday for the space, it’s better to replace your old wardrobe with a bigger one.

Impact of Caffeine

Unlike typical Google update, Caffeine didn’t brought any negative impact on specific sites. However, some sites did see a drop in rankings and on organic traffic

As with Caffeine, Google gained the capacity to crawl faster and produce fresher results from a larger index. Sites that covered new stories quickly were rewarded.

Earlier sites would only have this advantage if they were in the fresh category in the old indexing system, now anyone could take advantage of this speed.

While the Caffeine Update had little direct impact on rankings and faster indexing of new content, it set the stage for some massive changes to come.
