It's often noted that the name you choose for your site can inevitably help rank more favourably in the search engine, for example, if you have the domain hairdresserskendal.co.uk you will undoubtedly gain a huge advantage over the other hairdressers in the same area competing for the same term. Take into account too the fact that a hairdressers may not attract as much online interest as, for example online shops, and as such this type of business may not see the benefit of having a website and therefore, not invest. When talking about bigger and better competition then it's worth having the selected domain, however, the domain pointing to the main site itself does not justify any increase on ranking.
