But with more websites implementing push notification feature, Googlebot developers are on the point of adding support for HTTP in future.” It should be recalled that in April 2016, John Mueller said that the use of the HTTP / 2 protocol on the website does not directly affect the ranking in Google, but it improves the experience of users due to faster loading speed of the pages.
Most of the other reports that come to us is just information that we collect and can use to improve our algorithms in the future.
For instance, one algorithm can be used to display a letter on the search results page.
Therefore, we believe that counting the exact number of algorithms that Google uses is not something that is really useful [for optimizers].
The reason is that the crawler already scans the content that fast, so the benefits that the browser receives (web pages loading time is decreased) are not that important. We are still investigating what we can do about it.
In general, the difficult part is that Googlebot is not a browser, so it does not get the same speed effects that are observed within a browser when implementing HTTP / 2.
