Need a Caffeine boost? After much anticipation and discussion, Google's latest 'big update' is officially here.
Unlike many major Google updates, which include alterations to the factors Google uses to rank pages, Caffeine instead represents an update to Google's web indexing system. The result: Google says Caffeine "provides 50 percent fresher results for web searches than our last index."
Google software engineer Carrie Grimes explained what Caffeine is about on the Official Google Blog:
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. That means you can find fresher information than ever before—no matter when or where it was published.
Caffeine lets us index web pages on an enormous scale. In fact, every second Caffeine processes hundreds of thousands of pages in parallel. If this were a pile of paper it would grow three miles taller every second. Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles.
Google sees Caffeine as being crucial to its ability to "build an even faster and comprehensive search engine that scales with the growth of information online" but it's one major update that will have little direct impact on SEOs. According to Vanessa Fox of Search Engine Land, "Google told me that this change doesn’t make any of the crawling, indexing, or ranking factors more or less important than before. It simply makes crawled content available in search results more quickly than before..."
That will be music to the ears of many SEOs. If Google is being honest, there's not really much you can -- or need -- to do when it comes to adapting to Caffeine. If you're doing right by your SEO, Google will do right by you, just more quickly perhaps.
The catch: Caffeine might very well have an impact on your position in the SERPs at some point in the future. While Caffeine is focused on indexing in and of itself, it provides Google with the ability to collect a lot more metadata about the documents it indexes, and it would be surprising if Google didn't look to apply that metadata in some fashion to the SERPs down the road.
Of course, SEOs aren't likely to get too comfortable. Even if Caffeine won't have an immediate impact on rankings, Google is still performing other updates as usual. So the only refreshing thing about Caffeine is that such a major update will cause so few headaches.
