Even with the public testing and feedback there is still some mystery surrounding how far this new indexing system will go- will it be limited to search, or will it be applied across all of the Google online structure? For, now we don’t have those answers but we do know what Caffeine is and how it will change (or not change) your search results. 

Google has stressed the fact that most users (i.e regular users) won’t notice any major differences- even though these changes are major (MAJOR). In fact, Caffeine basically is  a complete and total re-write of Google’s indexing system. The motivation behind these changes is to give the searcher, — power or regular, —  a much better overall search experience. Caffeine will give you faster, more accurate, and more comprehensive results- at least those are the goals. 

If you go to www2.sandbox.google.com and give Caffeine a spin (like I did)  you will notice some of these goals have already been met. I entered “Nehmedia” (of course) as my search term and my results returned within .05 seconds- I also tested this on Decaf Google (aka www.google.com) and my results were returned in .08 seconds. I also tried a more frequently searched term “Shoes;” Caffeine returned the results in .18 seconds and Decaf Google returned my results in .23. Conclusion: Caffeine is faster than the Google we use today. 

Another interesting aspect of Google Caffeine is that this new indexing system is going to make your time from launch to index much quicker,.Meaning: the time between when you submit a document to be indexed and the time it is made searchable should be much shorter- which is pretty fantastic for those of us in SEO.

Also very important to note from the SEO standpoint is that it seems (to me at least) that a lot more emphasis is going to be put on keywords. The top results have the exact words you searched for and in the order you searched them in.

More emphasis is also put on recent activity and content. When I searched my name on Caffeine, the Facebook results were at the top. In Decaf Google, the top results were a mix of articles containing my name. I can only deduce from this that websites with more recent activity are pushed to the top of the results. This could have a huge impact on SEO; if we want our clients websites to be highly ranked we are going to need to regularly add content or make changes to the site. Caffeine will also return more search results than normal Google so your search becomes more comprehensive- they are making it very hard not to find what you are looking for. News is changing as well. Caffeine focuses on real-time updates and has set in place an algorithm to make sure that as news is updated, so are you. 

Many people have been wondering what set Caffeine into motion and a lot of whispers (and yells in some cases) have been speculating that it was the recent Yahoo-Microsoft merger. Not so, says Matt Cutts (and he would know). In fact, according to Cutts, Caffeine has been in the works for months and the timing is coincidence.

I believe him. It would have been nothing short of a miracle for engineers and technologists to have created this as a reaction to BingHoo (or whatever you want to call it) and have it up and ready for testing so quickly. Pretty impossible, even for Google. Nevertheless, it is competition- and fierce competition at that. Even if it wasn’t meant as an answer to the merger, it is an answer to it. 

For regular searchers, Caffeine won’t mean too much of a difference in results. As Cutts said, the changes are “primarily under the hood”.  Google will still return relevant results- just faster and more comprehensive results. Power searchers and those in the “know” will notice some significant changes though, and SEO needs to take note of them because it will effect our methods and strategies.
