Hey guys I had a dilemma today I hope you can solve. I was wondering how the domain .whatever affects seo and if it does at all. My situation is I want to build several small/temporary sites to test some traffic methods, at least 15 of them. Rather than shelling out 5-10 for each domain name, I thought about just grabbing a free one ,( .tk, .co.cc, .co.nr) How would these fair in search engine rankings? How much of a difference does it make?
