On 1 April 2022, the algorithm upgrade was completed, having irreversible effects on non-responsive sites. In addition, it is estimated that around 60% of searches are made via smartphone and tablet devices. Your potential customer could be there, you can’t miss them. Furthermore, if you try to do a search on Google from your PC and your smartphone, you will notice that the results are different, because Google tends to differentiate between the 2 search pages. Not having a responsive site not only means losing business opportunities but also allowing your competitors to be present in your place and increase their authority on the web.
