Google’s Caffeine is a site indexing capability that was originally put in use in 2010; it was Google’s offering to the online world promising better and faster indexing capabilities. Of course, many questions arose at the time and continue to surface about this technology, primary dealing with the area of search engine optimization. In an effort to rule out common misconceptions, here’s a quick overview of what Caffeine has done for SEO.

One of the worries most people had about Caffeine was that it would change how websites are ranked on its search engine. In prior years, Google was pretty much predictable about its criteria for classifying internet locations, which in turn drove strategies for web marketing. Changes in how Google ranked websites meant researching those new methods which in turn led to the implementation of new web marketing procedures.

For many who handled SEO, this kind of scenario appeared absolutely daunting and a great deal of speculation existed if such a change even could be implemented. After all, web technology is continually evolving and changing, which would have a similar effect on the metrics used by the search engines to rank websites. Thankfully, the changes created by Caffeine in the SEO realm were not overwhelming as the main purpose for this technology was to make the search engine’s indexing capabilities much more efficient and reliable.

It is important to understand how Caffeine affects Google’s search engine results. Originally, Google’s index had several layers, each one refreshing at a different rate and some much faster than others. Refreshing a single layer meant going through the entire web which took a large amount of time and inherent delay.

Caffeine presented a new approach in indexing websites. Instead of scheduling an index and doing it by layer, it took a real-time approach by constantly analyzing the web and updating the search index continuously. When new information or page updates were found, it was immediately added to that sequential listing. As a result, the search lists started being updated in real-time with the fresh, high quality topics from every part of the globe.

As for SEO best practices, the changes that came about only enhanced the capability of SEO to maximize sites and pages in that real-time internet world. Here are a few areas that Caffeine affected.

Load Time – An increased importance was placed here to construct a website to quickly load its content or face reduced ranking.
Content – Nothing really new here; the change was to reward fresh, quality postings.
Consistency – Changes here were a bit more relevant towards encouraging a well-organized, well-planned both page and web layout by not only rewarding good examples but actually penalized poorly organized websites.
Size – Quality will always be a primary criteria for Google; however, there are rewards to be earned from Google for websites with contains a lot of quality content.
Configuration – All of the various parts of a website relating to content must work well together and be relevant to each part; this includes titles, keywords, back links and how often all content is refreshed. This has had a big impact on how articles are ranked for the keywords they contain.
