A month after May Day which impacted long-tail keywords, Google rolled out the Caffeine update which brought about a new web indexing system. It was announced back in August 2009 with a glimpse of a massive infrastructure change that prioritized real-time crawling, index expansion, and ranking integration. The final update was launched in June 2010 after several months of testing.
The Caffeine update was developed to keep up with the ever-evolving web and the rising expectations of users. Web content was rapidly becoming more complex with the integration of more media such as images and videos on top of the text content. Moreover, searchers want the most relevant content right after they typed in their query and site operators expect their pages to be found upon publishing their posts.
Google explained that the infrastructure change let go of the old index which had several layers. The primary issue with the previous model was that it refreshed some layers at a faster rate than others. This process implied that users don’t get access to all web pages that are relevant to their query; only the ones that were included in the update. The old index also led to a delay in the search engine’s discovery of a page and making it available to searchers.
With this update, Google analyzes the web bit by bit and refreshes its search index continuously and globally. As bots find freshly-published pages or new information on existing ones, the team adds the data straight to the index. Caffeine, which was built to be a robust foundation for future expansions of the search engine, can process thousands of pages in parallel every second.
Caffeine led to a boost in the search engine’s raw speed as well as a 50 percent fresher index, as reported by Google. The update benefits both searchers and blog owners since it ensures that all content is discoverable within seconds after bots have crawled through newly-published pages.
These were the significant changes brought about by the update:
Search has never been the same since Caffeine rolled out. It did serve as a robust foundation for future algorithm, ranking, and infrastructure changes. One particular update was Google Freshness which prioritized more recent content in SERPs. It’s all the more crucial for you to publish new posts regularly to maintain and improve your position in the results pages.
