okey so I have two ideas for a domain name for a video site: one is 10 letters and ends in "xtube" the first 5 letters = a word that is the most important word for the niche (it is the niche). X = just a random letter i put in, and tube = videos. the other domain would be 8 letters (shorter). But it would not have the main keyword. It would be two 4 letter words, that are not as closely associated to the niche (though they are related, just not as close). This domain might sound more catchy. But random ppl would not know what the sit is about unless they click it. First domain ppl would easily know. example: kitchenxtube.com vs. weetable.com first one ppl will think: videos about cooking second one ppl would be like "uhh maybe about cooking?, easier to type/remember" thanks guys.
I think the second would go over better - the first might have your keyword but it also has an unnecessary letter (the random x). But then again I own a site called the Minty Ferret, so I'm probably biased.
