Is it worth using Tower-Defence-Games.net for seo purposes? TD-Games.net will probably not do as well with the search engines, but it is easier to remember. Which is the smarter choice? Thanks for your help!!
It definitely helps to have your keywords in your domain name. So I would probably lean towards tower-defence-games.net For certain websites it helps to have a short, easy to remember domain name. That depends if you expect much direct traffic from people just typing your url in the address bar. If your visitors have decent internet knowledge, it is not so important to be able to remember your domain name. Those people are smart enough to bookmark the page.
defence is the british/uk spelling. Google knows synonyms, so chances are it wont make too much difference, however it might think it's more UK focussed than US, but bleh who knows...
