Google testing new Caffeine search engine

Posted: 11:18 AM ET

Google has announced it is testing a new form of search architecture codenamed "Caffeine," and the company wants your help to examine the results.

According to a post on the Google Webmaster Blog:

For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google's web search. It's the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions.

Google's current search infrastructure relies primarily on hyperlinks. Pages that receive a large number of incoming links from external sites are given a higher PageRank and are more likely to appear near the top of Google's search results.

Google is unlikely to stray far from its successful PageRank system, but the possibility of new search results is a huge deal to companies that rely on Google-generated traffic or those who have invested heavily in search engine optimization (SEO).

Business Week claims "Caffeine may cause corporate jitters:"

Google suggested that Caffeine could change search results, which raises the prospect of companies' needing to change their search engine optimization (SEO) to protect their Google ranking.

To test Caffeine for yourself, visit: http://www2.sandbox.google.com/

Google admits "most users won't notice a difference in search results," but the company is still looking for "feedback on the differences between Google's current search results and our new system."

Did you notice any substantial differences in your searches with Caffeine? Were they more accurate than Google's current results?

The results are practically identical for the few searches I did on Caffeine. It's hard to say what has changed.

[...] Google now testing it's "Caffeine" engine, the results are shifting around. Searching my name on Google no longer results in my Serverboy [...]

When I tried to go there, it said the site was down.

Googled a search across a specific site using Caffeine and current release; Caffeine only returned 3 entries while current release found 23. The latter is the correct number.

Will this give me a heart attack the way Redbull will? It also sounds like Caffiene is goinng to behave more like Cuil.com Which was created be a former Google employee. The Caffiene Sandbox is currently down, but I will try it later.

According to Google at SES in San Jose last week, the majority of the changes is the infrastructer, now the search engine indexes the web. There is little changes to way rankings are done. Google regularly updates and tweaks their algo. I don't why this is news and other updates, like the vince update in March which did affect many major brand rankings is not news.

Google's rise to success was in large part due to a patented algorithm called PageRank that helps rank web pages that match a given search string. When Google was a Stanford research project, it was nicknamed BackRub because the technology checks backlinks to determine a site's importance.::

I think that the texture of both of these cocoa – flavored rice cereals makes them fun to eat. Water flushes out the toxins the body produces as it burns fat and it gets rid of excess sodium in the system.
