I suggest you try to entice a webmaster by stating something like "Tap into a new source of revenue!" etc. Most people won't realize that you could simply stick a small ad button for a dating site and get surfers interested.. You need to sell the sell.
Btw, I realize you do mention this in your text - but it's a few sentences in. I'd suggest making it more of an instant thing viewers see, or become aware of..
Cheers,
