How Google Evaluate New Search Algorithms

Few days ago Head of Search Spam Matt Cutts gives us a video that describe how Google evaluating new search algorithm which one they are going to use or which one they are going throw away.

A question was asked by James Foster of Sydney:


What metrics Google used to calculate that one function of the ranking algorithm is gives the good quality result to user than other?

Matt Cutts give the answer into the three steps, that how they evaluate search algorithms:

  1. They test the results of the algorithms and compare their results rank with the new algorithms offline, If the URLs in the result are of high quality then the last algorithms takes place. The quality of a URL is based on search quality raters that how they rate the URLs in the last cases. If the URLs are not rated, then Google could request the raters  to rate the new URLs or benchmark the previous search result to this set of new test. Based on these metrics, Google can decide to carry on to the next level.
  2. Online Tests, here Google have the sample of real live searchers and place them to the new results with the new test algorithm sets. If Google catch the high rate of clicks in new search results, then it shows that the results in this are better than older ones. Matt Cutts said that, this case is not for always but in general the more click at the specific search result page more is the quality result.
  3. After that the Search Quality Launch Committee of Google have to decide that the algorithm is going to live or not. Matt Cutts told that Google have a “very pretty system” but they need to filter some of his processes within the workflow.

Game Of Thrones Game Leads Into Season 5

Telltale Games has kept their Game of Thrones project under tight wraps over the past year. On Tuesday, they finally shed some light on the adventure game based on the HBO show. Game of Thrones: A Telltale Games Series stars House Forrester. They appeared in George R. R. Martin's novel A Dance with Dragons but haven't been seen in the TV show yet. The Forresters reside in the Wolfswood in northern Westeros. Their stronghold of Ironrath has stood at the edge of Westeros' largest ironwood forest for fifteen hundred years. "Ironrath is a testament to the strength and endurance of Ironwood," Telltale explains . "The Forrester house words are 'Iron from Ice', which echoes their belief that - like the ironwood itself - the adverse conditions and unforgiving landscape of the North only makes them stronger." Like their bannermen at House Glover, the Forresters are loyal allies of the Starks. This puts them right in the middle of the War ...

Matt Cutts Is Going On Leave For Several Months

Matt Cutts, Google’s head of search spam, announced today that he will be going on leave for several months. Matt cited the need to spend more time with his wife as being among the key reasons behind his decision to go on leave. When I joined Google, my wife and I agreed that I would work for 4-5 years, and then she’d get to see more of me… And now, almost fifteen years later I’d like to be there for my wife more. I know she’d like me to be around more too, and not just physically present while my mind is still on work. Matt’s leave is scheduled to start next week, after which time he will be gone through October. He has the utmost confidence in the webspam team while he’s gone, saying that they’re much better at spam fighting than even he is. Matt won’t be checking work email while he’s gone, at all. This is a point he repeated several times throughout his announcement. Gmail filters will be set up to forward some of his outside email to individuals on the webspam team, but...

HTTPS As A Ranking Signal

Security is a top priority for Google. They invest a lot in making sure that their services use industry-leading security, like strongHTTPS encryption by defaul t. That means that people using Search, Gmail and Google Drive, for example, automatically have a secure connection to Google. Beyond their own stuff, they are also working to make the Internet safer more broadly. A big part of this is, they are making sure that websites people access from Google are secure. For instance, they have created resources to help webmasters prevent and fix security breaches on their sites. They want to go even further. At Google I/O a few months ago, They called for “ HTTPS everywhere ” on the web. They have also seen more and more webmasters adopting HTTPS (also known as HTTP over TLS , or Transport Layer Security), on their website, which is encouraging. For these reasons, over the past few months they have been running tests taking into account whether sites use secure, en...
