Hello, how are you ? does it matters for SEO if i have domains like ab.com or a-b.com ? Thank you very much Regards Greg.
Usually it's better to have a domain with no delimiters (_ or -). This is better for a couple different reasons. Better chance of direct type-in traffic. Past visitors revisiting by direct type-in. Either way they can both be read the same to search engines, so I would go on availability.
That right plus google give more weight to domain without - as its consider as non original domain of the services provider or of the brand name
Try to have a domain with no delimiters (_ or -). But if the domain name you are looking for is not available then you can go for the domains with the delimiters.
