I have been doing some keyword research for a few days, i got a dozen niches with about 100 keywords for each. I dont want to buy a domain for each niche. I have never used sqidoo and hubpages, i know most of you here use it as a landing page. But what's the catch while using these 2 web 2.0 properties, do they allow affiliate links? Which one is better and more "visible" on big G ?
