What Is Google Algorithm?

What Is Google Algorithm

You can find the meaning of this term in the word algorithm itself. By definition, the algorithm is a set of instructions employed for solving or executing any problem of that system. It is similar to the case of the Google Algorithm.

Google uses some predefined and established methods to rank the websites on their SERP. For instance, when you search on the topic of “best mobile phones”, Google will show you many websites on their search results page for best mobile phones only.
