A couple of weeks ago, Google announced the completion of Caffeine, their new web indexing system. They’re pushing its speed, its comprehensive coverage of the web’s content, and – this is where it gets interesting – the improved “freshness” of search results.

It’s a reaction to the ever-increasing amount of content on the web. The official Google blog explains it like this:

Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.

With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index.

What does this mean for potential developments in the SERPs that Caffeine will allow Google to develop? We’ve seen the inclusion of video and real time search. Is this going to lead to more complex SERPs, moving further away from Google’s original design simplicity?

By altering their SERP generation process to reflect the rate at which content is being published, Google have made it more important than ever – and easier than ever – to drive traffic to your site via updating your content.

At Moo we’re well aware of the results that can be achieved through well optimised, well written content. Caffeine isn’t going to massively revolutionise SEO; it’s a reflection of the importance that Google – and its users – place on “fresh” content. Quality and quantity aren’t mutually exclusive, and all SEO strategies need to be user-focussed; Caffeine consolidates the importance of good SEO content.
