One of the most common complaints of critics (and competitors) have against Google is a company — despite its numerous outdoor products and initiatives is very secretive about the countless algorithms that power their Crown jewels, a Google search. In other words search is a black box. Google's argument was that it should be this way — if he told everyone exactly how the algorithm works, it would be much simpler games and search results will suffer.

In any case, there are a lot of mystery surrounding search, which is why the video is now posted on a blog Google is so interesting: Google gave a quick video guide detailing how its engineers gradually adjust algorithm which — according to the video gets tweaked with more than 500 times per year.

Video is only four minutes and worth watching in its entirely, but here's a quick rundown on how changes to search goes live:

First Google engineers define the complex motivations of sites, which don't work as well as Google would like them to later engineers were trying to identify the different signals (Google doesn't really get into what these signals suggest) that can be used to more effectively respond to this request. these new results are then evaluated by a qualified employee that is not an employee of Google. Further results are pushed live a small number of users. Analyst then assigns objective look at the changes and how it performs in tests.the proposed change were submitted to the Panel, search quality, which approves or rejects it.

The video also turns into a quick joke about what Google calls "full replacement pages. This applies to the times, Google looks at your request, you misspelled words, and then presents the results for the correct spelling, rather than simply offering proper spelling and display results with errors. To test this, Google looked at how many times users clicked on a link to clear the results of their initial request (which, according to Google was a typo), Google decided that until the escape hatch just pressed 1 in 50 times, and good changes. And passed the test.

Google provides search and advertising services, which together seek to organize and monetize the world's information. In addition to its dominant search engine, it offers many ...
