Although Google rolled out Caffeine this summer, people are still finding its true impact. From the very beginning, Google has said that it was not a change to the ranking algorithm. However, it could impact ranking and many other areas, as Vanessa Fox of Nine By Blue explains.
She tells WebProNews that Caffeine consists of how Google crawls, indexes, and stores content online. Once the search giant crawls a page, it instantly takes that page and runs it through every part of the indexing pipeline and pushes it live. This means that a page could be live within a minute after it was crawled.
Another important note about Caffeine is the fact that it allows Google to associate more information about pages. Google now has the capacity to store any type of data in the future. This element is important since the Web is continuing to grow. In the future, Google could simply add signals if it needed to, as opposed to building a new infrastructure.
“This lays the groundwork for potentially changing the ranking algorithms in the future,” says Fox.
Speed is another factor of Caffeine that is natural since the Web is growing. Fox points out that the old index would have gotten overwhelmed and would, therefore, not be fresh.
Fox also addresses the MayDay update, which was an algorithm update, and what its implications are. This update received a bit of resistance due to its impact on content farms, forums, and product sites. Many of these sites dropped in ranking partially because they do not have a lot of links or content on them, which are prominent signals Google uses for ranking.

Very nice, Vanessa. Thank you. Good overview of google caffeine. Will look for your book on amazon. Many thanks.
I understand her MayDay explanation, but what she explains Google wants is simply not possible 1000′s of sites online. Look at all the great resource directories out there that were hurt for no good reason. BY her explanation Amazon would have gotten killed during this update. Did they, nope.
Amazon has trustrank (the invisible ranking for folks with stock market money, educational or governmental authority, etc). So you are right. No matter what Amazon, Ebay, GM, Cars.com, Huffington Post, Fox News, etc. will never have to worry when Google flips the switch. This is simply because these sites get to sit in a special box, with special rules.
Why don’t you two get a room? Lol!
I like how Google is indexing content so much faster with Caffeine. It keeps readers updated with relevant information.
Any improvement that Google makes to increase the speed that they push data out to the SERPS is a good move, even if it affects ranking changes. It keeps everyone on their toes. Thanks.
Vanessa IS a fox. I adore brainy chicks.
I see Caffeine as a good thing, useful Google improvement. It makes SEO more interesting.
i think this is a good thing
Add a signal? I would like to see Ms. Fox pre-define(provide a definition) the term “Google signal”. The video talked about a link tag or an H1 tag as a signal – then Ms. Fox continues to “invent” the term “signal” as if everyone would know what that term meant in terms of SEO and which I had not heard till now…If she was Matt Cutts then I would respect using a new term but she is not Matt Cutts.
Thanks for explaining more about the mayday situation. I have a blog with original content that is very niche targeted. Apparently, by what you have said,
I would say Google caused my traffic to decrease because I was a blog that was only a year and four months old with few backlinks.
Thanks for the explanation
