The update to the review ranking algorithm was launched in parallel with the update to Google’s core algorithm, previously announced on November 2. After the update is released, Google will be able to even better prioritize quality reviews and product reviews in search results. Google said this is the last public announcement of an update to its review ranking algorithm. In the future, the system for working with reviews will be improved on a regular basis, but changes will not be announced.
