Imagine an e-commerce that, for example, does AB tests . Once these experiments are finished, the person in charge of managing the situation forgets to remove one of the two pages. Here, for Google we are in the presence of two very similar pages, not to say identical, so the first advice I give you is to go and check the presence of "useless" pages on your site and eliminate them. By useless I also mean pages of little value that are not generating performance.

As a rough guide, you should have more or less the same number of indexed pages that you counted in the previous operation. If the number of indexed pages is too high, intervene by analyzing which pages might have escaped your attention and that in reality should not be indexed.
