According to Google spokesman John Mueller, short domains and URLs do not affect SEO performance in any way. These pages have no advantage over the competition when it comes to SERPs.
“Domain length or URL length is not a scoring factor when ranking sites in Google. Maybe she helps in marketing, but we only use it for canonization, ”said Müller. on your twitter…
Canonization refers to the process when Google removes index.html-like signatures in page URLs or uses shorter URLs when there is plenty to choose from (two links with the same content but different URL lengths).
He also added that he sees people with a lot of enthusiasm clicking on short links, but this is not related to SEO. They just like these URLs visually.
As the users pointed out under John’s post, the point may be that such links are easier to read, more credibility arises in them. That is, it is the perception of the brand by living people, and not by Google robots, that plays an important role.
The only URL limitation that Google has mentioned at least once is the maximum length: it must not exceed 2000 characters. And then the company did not claim that longer links cannot be used. It sounded more like a recommendation.
