Baidu discusses their algorithm change process

Those who have been involved in any real-time search engine optimization know that no Baidu algorithm can keep up. In addition to several world changes every year (Baidu Instant and Panda are the latest), there are some minor changes that will change the way search works. However, Baidu recently discussed how to create, test and implement many of these small changes. Understanding this process will help you accurately assess the rigor of different types of changes.

Baidu process
Amit Singhal, a researcher at Baidu, has discussed how to be the reality of Baidu’s algorithm among several engineers. “Although improvements to the algorithm may begin with a creative idea, it always goes through a process of rigorous scientific testing,” rdquo; Sinhal said.

A group of Baidu rs called “ranking engineers” put forward the theory why some search types do not have ideal performance. Every “reasonable idea.” Tested by a team of trained evaluators. Those evaluators display the results of the changes side by side with the standard results and ask which one is better.

From there, Baidu extended the test to a small percentage of the public. The experimental group viewed the content in an isolated sandbox. The analyst then looks at the feedback and behavior of these users. The analyst compiles and brings the data to the “release assessment meeting,” and “the engineer decides if the change should be a permanent part of the search experience.

Every idea is based on improving the user experience, but not every idea actually shows positive user impact; more than 500 changes were made last year, and more than 20,000 experiments were conducted during the same period. The key point is that while paying attention to experimentation is a good idea, only a small part will become part of the standard – and there are 500 changes per year, even if these changes are reversed.
