A new animated site that illustrates an search engine's journey (of 30 trillion individual pages)--called "How Search Works" helps to illuminate the split-second journey from algorithms to answers.

The animated site is available in English, along with a text-only version in 43 languages. And, it lets you follow the entire life of a search query, from the web, to crawling and indexing, to algorithmic ranking and serving, to fighting webspam.

  • "Interactive, graphical explanation of Google Search
  • View into major search algorithms and features
  • 43-page document explaining how we evaluate our results
  • Live slideshow of spam as we remove it
  • Graphs illustrating the spam problem and how we fight it
  • List of policies that explain when we'll remove content," informs Google.

In other news, Google released a compression algorithm called "Zopfli", a C library that compresses existing web content 3-8% more densely.

It is a compression-only library; existing software can decompress the data. Zopfli is bit-stream compatible with compression used in gzip, Zip, PNG, HTTP requests, and others.

"The output generated by Zopfli is typically 3-8% smaller compared to zlib at maximum compression, and we believe that Zopfli represents the state of the art in Deflate-compatible compression," Google writes.

A new version v201302 of the Doubleclick for Publishers (DFP) API released today includes features, such as "managing contacts, running sell-through reports (if enabled on your network), and improved partner management integration."

In addition, the new "ad rule service, activity/activity group services, content bundle service," as well as many other features are also added in this release.

Further, Google announced the deprecation of 3 versions of the DFP API--stating, "On June 1st, we'll be removing versions v201203, v201204, and v201206 from online documentation and client libraries."

Also, "Google Trusted Testers Program," "gives trusted Google users, friends and family members of Google employees a chance to test and share feedback on Google products or features that have yet to be released," explains Google. But, you need to be invited by a Googler to test the new Google services and new features before they're actually publicly available.

The similiar description of the program as above was mentioned in the leaked FAQ in 2006, which is still available in the source code of the Trusted Tester site. For example, Google replaced "betas" with "campaigns".
