Some customers additionally typically discover that updating wastes necessary assets and pushes spam websites to the highest. Final yr, you can discover a pointy deterioration within the high quality of search, which was corrected by Google in a rush.

Matt Cutts launched a brand new video through which he mentioned the difficulties related to the discharge of the replace. Typically, the complete course of from the looks of a brand new model of the algorithm to the discharge takes place in three phases. new first exams disconnected. The corporate has specialists who work with the up to date search engine and report the standard stage of the subject. If the actually good websites are highlighted and the quantity of spam on the high has decreased, this means that the event of the replace was profitable.

Step one is to check the previous drawback with the brand new one. That is additionally an important course of, exhibiting if even higher assets have disappeared from the highest of the search. Generally the algorithm hurts good tasks. This shouldn’t be allowed, as a result of it’s troublesome to revive them within the search outcomes later. Site owners who create such assets shouldn’t pay for errors within the algorithm. The primary stage ends with a abstract. If the outcomes of the offline exams have improved, the second stage of replace verification begins.

If the algorithm failed the primary stage, it’s improved after which retested. This course of can take a very long time.
