I am about to embark on a CPA experiment involving a domain with a multiple times a month search. Checked it on Google Keyword tool and the keywords had several thousand searches a month. I was able to find an info which had all of the keywords included, rather an exact keyword search keyword set. I am testing an .info on this to see what happens. Later I will likely upgrade to a harder to get .com.
A wordpress blog with the CPA offer will appear and I will be writing short articles and doing
SEO on this. NO
PPC. I am preparing for possibly months before I see much. I was able to grab a 99 cent .info so this should be a lo-cost experiment. Hey, you never know, people have made empires from a single shoestring.
