Morning Simmo,
I like the idea of aiming for different types of websites but like the others I agree a sex site might not be ideal, however there are a gazillion other types of sites that could be harvested or utilised and as cat idicates its a game of seek and find.
I would imagine the best type to look at would be one with a membership that has a good hit rit and regular visitors – reunion sites – different types of sites that have a message board ( a busy one)
It would be a bit of a gamble for you to advertise on these types of sites – but gambles sometime pay off…….
