As highlighted a few years ago by Bill Hartzer on the Search Engine Journal website , the use of new gTLDs does not have a significant impact on the conversion rate of AdWords (now Ads) campaigns.
New gTLDs - SEO
This is as far as the so-called SEM is concerned , in which we can uses of twitter notice how (over the years) the new gTLDs have gradually nibbled away at additional percentage points in terms of the conversion rate.
As regards organic traffic , the beating heart of the discipline known as SEO , Mr. Hartzer suggests that (contrary to what many SEO Specialists have always claimed) the new extensions do not bring any disadvantages and, in fact, could even provide some benefits in the long run.
The important thing, says Bill Hartzer, is to carry out a complete and correct migration (from the domain with the classic extension to the version with the new extension) of all the elements of the site.
SEO Migration: The Technical and Strategic Aspects.
Hartzer himself gives an example that clarifies any possible doubt, that of the site StlMotorcars.com and the subsequent transition to the .CARS extension . The data analysis, done through Analytics and SEMrush , did not highlight any worsening but rather a growth of some important keywords for the site in question.
