As I have made some research on different "SEO" websites and blogs, everyone recommends NOT using dash/hyphen in their domain names for readability and not looking spammy. I did not found any real data on if only one hyphen/dash is SEO harmful or not.
For a simple and easy to remember domain. Example:
sports wear should use
In my opinion, the dash version is easier to read and possible harder to remember but what about SEO? One single dash helps the keyword "sports wear" or make it difficult to match the domain for the web crawlers?
Anyone had experienced / tested this fact?
