I would like to share my experience with AWB with other users. So i created this forum thread, to keep those interested updated on my quest.
I bought a new keyword related domain for two days ago. Punched in a load of related keywords and my site are already indexed in Google :-) The keyword related to my domains have a estimated avg cost per click of 137$
So i hope i will get some good traffic.
Thomas is right with what he has told you above
As regards your high paying domain - you need a domain that preferably has a good to high exact search term and low competition. (You can still do well if there is a lot of competition also). It doesn't matter what the cpc is.
If you cannot get a direct match, than add a suffix.
Your domain will be loaded with lower estimated cost per click keywords and these are what your adsense ads will be related too - not so much your domain name.
I know some people won't entirely agree with this - but I base it on my own experiences.
So don't be disappointed if your adsense isn't as high as you had hoped based on your $137 estimated cost per click kw.
Some of my niches are the hot tub, rv, harley accessory niches - if you ever get stuck for ideas and tho' not great earners alone - together they do very well.
Good luck with your awb venture.
