One of the criticisms most common complaints (and competitors) who are against Google is that the company – despite its many products and initiatives open – it’s very secretive about the algorithms for a number of jewels in the crown, who have power in the Google search. In other words, the search is a black box. The argument has been generally Google has to be – if they told everyone exactly how the algorithm work, then it would be much easier to play, and the search results would be affected.
In any case, there are a lot of mystery about the search, so that the video posted today on the Google blog is so interesting: Google has taken a walk through quick video that details how engineers gradually adjust the algorithm , which – according to the video – is set to more than 500 times a year.
The video is only four minutes worth seeing in its entirety, but here’s a quick summary of how a change in the search goes live:
First, Google’s engineers to identify a set of “motivation of the searches” that are not working as well as Google wants them.
Then, engineers try to identify the various signals (Google really does not get into what these signals mean) that could be used to better respond to this consultation.
These new results are then judged by a trained worker who is not a Google employee.
Then the results are pushed to live in a small number of users.
An analyst is assigned to look objectively at the change and how it’s performing the tests.
Finally, the proposed amendment is presented to the team flight to quality, which approves or denies it.
The video also goes into a quick story about what Google calls “full-page replacement. This refers to the time of Google looks at your consultation, you decide that you wrote it wrong, and then presents the results of the correct spelling, not only suggesting the correct spelling and display the results of the results with errors ortográficos.Para test this, Google looked at times users to explicitly click on the link to the original query results (which Google thinks is misspelled) – Google decided that if this “escape hatch” clicked only 1 in 50 times, was a nice change. He passed the test.
