Search engines have various algorithms like quality of the content, difficulty level, and relevancy to rank them on Search Engine Result Pages (SERPs). According to the quality of the content, web pages are ranked from most relevant to least relevant order.

Whenever a user searches for something they want to know about and puts their query in the search bar, these processes take place to provide the user with the best and most relevant results.


It is the most important and prioritized algorithm of Google that takes the help of Artificial Intelligence and Machine Learning to predict and learn how users interact with the search results provided by search engines according to their previous activities.

It’s a part of Google’s Core algorithm. It continuously tries to improve its predictions by observing the user response, and the existing data and tries to give better results for every query of the user. 

The interesting part is, that whenever it notices a URL that is low ranking but provides better quality and lots of value than the high-ranking URL, then it edits the search results accordingly and puts the better URL on the top.
