Google Algorithm Updates and Changes History

To provide the best possible results for each query, Google updates its algorithms a thousand times or more than that in a  year. Their changes in the algorithms are very small, and you will hardly notice anything. But every once in a while, Google makes some changes to their algorithm that affect the process of how we do search engine optimization.

In this post, we are going to discuss all the changes in the algorithm that have occurred over the past few years. But before we start, if you want to make sure that your website isn’t affected by sudden changes in the algorithm, then you can use the tool called “Google search console” to monitor where exactly you stand after the changes have been made.

So now let’s discuss some of the changes in Google’s algorithm that have taken place over the past few years ——
