It only matters if you plan on bidding on them as an advertiser. Just because you target them as a publisher doesn't mean you'll earn a high payout. It simply doesn't work that way.
I don't think so, because hosting is very competitive and they don't pay much, like $0.30, however when you're referring someone.. it's much more rewarding. I know this because I use to do it, and it's not worth the time unless you're site is popular or automated.
This is the most paying keyword that i ever met. serious injury claim = $141.85 But i cant make any site related to this. Because I dunno any thing related it. Dont search for high paying keywords. Just get some niche that you know about and make a good site then promote it well. Then it will convert more revenue than high paying keyword site which you are going to create.
From my experience, these are the numbers - 4 months of making money from Adsense in an "average" niche = 107$ 1 month of featuring affiliate products in that SAME niche = aproximatelly 200$ I think it's clear what's (usually) more profitable. It's affiliate marketing High paying keywords in Adsense are a fluke because they have high competition, and you will have tough time tapping into those markets. Better go with affiliate marketing.
