Google Caffeine

Google Caffeine It is an update of the Google crawler search algorithms. The purpose of this update is to provide more recent results in the Google index.

General information

Google Caffeine is not a conventional update like Penguin or Hummingbird, affecting the search itself or the search results lists. Instead, it consists of a fundamental change in Google infrastructure which was introduced in June 2010. The reason for its introduction lies in the fact that the World Wide Web is constantly growing (hundreds of websites are added daily) and its diversity in terms of multimedia content. The web contains videos, images, podcasts, news and much more. Google Caffeine was implemented in order to keep up with current developments and, in particular, to shorten the time between crawling and content delivery.

Practical relevance

Whereas the old Google index was based on a layered model where only the main layer was updated, Google Caffeine has radically changed this. The index is built by crawling the global network. Google searches for web pages, documents and other content and stores them in the index. Caffeine works by searching smaller and smaller parts of the web to find the most current content and store it in the index. This is called incremental search. Old content that exists in the index is updated with new content. Google used much of its infrastructure for this purpose. The used storage capacity of the index is 100 million gigabytes. Several hundred gigabytes are added daily. According to Google, content is being made available twice as fast.[1]

Relevance for SEO

The Caffeine update does not change SERPs or ranking factors. Instead, the content can be found more easily on the Internet, be it websites, videos or images. Both webmasters and users benefit. However, webmasters should pay attention that Google Caffeine substantially shortened the time between crawling and the results displayed in the SERPs. Google Caffeine has opened new alternatives to attract attention on the web, since it tracks content formats, such as images, videos, news sources or podcasts. Buzzword: rich media.
