Your domain name is not only the most prominet feature of your website but one that will make or break you,depending on how easily surfers can recall your URL.If you have a site that sells cat collars and your URL is 7-bobsthingy-jiggys.com OR ejb12-2348.com thats a little tuff to recall,next time you start looking for cat products.

The correct domain name for an your online business would be one that brings to mind:

1.Your products
If there was on short sentence that would describe your business what would that be?Then reduce that down to one or two short words or a phrase.
Now the fun part:
2.Choose a word that is easy to remember.
One word/phrase with no "-" in them,as most dont remember to add these in and your competitor will benefit from this who does not use a hypen in Domain name (URL). Catcollars (is of course the best but might not be available)
Collars
CatProducts
Catsmeow (easy to remember using an existing phrase)
TheCatsMeow
KatCollars(the draw back to this name is people that does not know the spelling differance of
Kats vs. Cats and your competitor will gain some traffic from this easily made mistake,but it is still a very good name,and one that I would choose.

3.Make domain easy to spell
cattusCollars(Latin for cat) Most would not ever think to look for cat collars under the name cattus,and even if you told them several would mispell it.
