Well, since the last year, Google has effectively introduced a pack of updates to its search engine which is known amongst those who are in the niche as the animal updates. Penguin, Panda, and Hummingbird significantly changed the way the search engine of Google works and the way it ranks websites.
Google has made it clear that the most important ranking factor is going to be the user experience. Therefore, the more user-friendly your website is, the highest chances you get to rank high up the ladder.
The user experience is going to be defined by a number of things, but a responsive website is certainly going to have the upper hand. Of course, how responsive your website is doesn’t just stop at being properly optimised for mobile devices.
The loading speed, the rate at which it’s going to load different pages, the overall interaction with the interface, these are factors that are going to determine how responsive your website is. This is why you need to make sure that you get all of this properly handled if you are to have a chance of climbing the search engine ranking ladder.
