Just curious would it really matter if you advertised your affiliate products using adwords via blogs? Is there much of a difference or anything?
Any good SEO will have things like blogs or articles out there using adwords to promote their product. I have a couple of blogs. Everyday i try to write at least on fresh new post...and I always include important keywords that are linked to my site. www.wordpress.com www.blogger.com the 2 best blogging sites....free!
I have SEO websites which contain blogs - I have websites that do not have blogs or articles, that I advertise on Adwords - these get some great quality scores and low min bids... from my experience, I'm succeeding without the need of blogs/articles etc. Think about it: Why would Google want a website on Adwords to have articles/blogs? What matters for Google is that the visitor finds what he/she is looking for - i.e landing page relation to the ad.
