I found this thread quite interesting because I recently registered backinjurysolicitor & backinjurysolicitors .com & .co.uk
Although it's much more specific and gets less searches per month, there are solicitors who specialise in back injuries, and they make thousands per client - probably more in fees than the injured get in compensation.
I've put a site up on the plural co.uk with the aim of selling advetising, and of course at getting it ranking for more desirable terms, like back injury comensation, etc.
Looking at other general sites that offer advertising to solicitors, they charge thousands per year for a small ad, so this is the route I'm going down with it.
I don't know if it'll work, but I'm sure there will be those who will be happy to pay to advertise on it.
I put a site on it about 4 days ago, it's already on page 1.
Even if I don't get any advertisers and a relatively low number of visitors I can put adsense on it - at £25+ per click it should be quite lucrative.
I think you might be better off doing something simlar, you'd probably make a lot more money from it.
If I get all of my advetising spots sold at the price I've put on them it'd bring in around £75K per year!
How mad is that?
