Caffeine:The New Google Web Indexing System

13 June 2010

Google has announced its new web indexing system called Caffeine. The good thing about Caffeine is it provides 50 percent fresher results for web searches than it used to do before. Certainly this would be good for the people who update their blogs regularly with new content. As Caffeine indexes blog posts or pages faster, anyone who is searching for information in the web will find links to relevant content much sooner now.

The reason why Google has build their new search indexing system is to help people find the latest relevant content and meet their expectations. People always expect good search results from Google. There are many blogs out there who are already outdated with information. But they just come in the first page because their blogs were established earlier. So even if a new blog has reliable information it might not come in a good place in the Google search results.

With this new web indexing system Google analyzes the web in small portions continuously and update the search index. Whenever it finds any new pages or new information on an existing page, it adds those to the index instantly. So users get fresh search results of new contents quickly where the old indexing system of Google were divided into some layers; some of which were refreshed faster and some slower. But the main layer used to update in every couple of weeks. So it had to analyze the entire web to update a layer of the old index which means there was a delay in indexing a page or post after anyone publishes any new content.

Here is a good video by Matt Cutt, the head of the Google search engine quality and webspam team explaining how the Google web indexing system works-

Now that the page indexing is faster and relevant, it’s good to keep an eye on updating the website regularly with new content. That way it will be more likely to get a good position in the Google search result and consequently it will also increase website traffic.
