These evaluators evaluate the practicality and quality of each content based on its professional knowledge, authority, and credibility.
“The resulting ratings will not affect the ranking of any individual website, but they do help us benchmark the quality of the results, which in turn allows us to build algorithms to identify results that meet high-quality standards on a global scale. “Google said.
