In August 2009, Google released a beta version of one of its leading updates known as Caffeine. The chief aim of this update is to speed up and improve the accuracy of the searches that take place on Google. Even though the changes are concerned with the speed and accuracy of searches, some online marketers are concerned if their position and ranking will be affected.

Google explains Caffeine as a new generation design for Google's search as it is the first step towards escalating speed of indexing and accuracy. The SEO world has been impatient and is striving to know how it will affect their ranking as Caffeine is not just an update, but the algorithms of Google searches have been refurbished.

This means it is very important in the digital marketing to track to the success of interactive advertising campaign and on SERP's of Google Caffeine as well. This needs to be done as this helps you comprehend what the algorithm of Caffeine focuses and adjusts your optimization efforts. This simply means playing between a plethora of keywords. To make things simpler, we have listed down a few observations about Google Caffeine:

Speed
Results are fetched relatively faster in Google Caffeine as compared to the usual Google search. It takes about 0.13 seconds to fetch results for the key phrase "SEO Blog" in Caffeine where as the old Google does the same search in 0.33 seconds. This is approximately consistent for all the searches done.

Index Size
The index size differs from keyword to keyword and the result is therefore still inconclusive.

Freshness of search results
There is not much difference between the freshness of the results in the two kinds of searches, namely normal Google search and Google Caffeine search. When you type in current events in the search box, both the versions pull up the latest news.

Video/Image results
Some of the search terms do no fetch many video results while some bring more video results. However, during the image search, the images that appear in top searches of old Google, those disappear completely during Google Caffeine search.
