We have recently launched a well thought-through google campaign on promoting our site
www.fone-me.com and see what happened. This is targeted phone sex traffic at a very low cost per click.
We have affiliates converting cam traffic at 1:10 with fone-me.com
Also right now we're beta testing our Live Cams that will add to phone sex (not the other way around).
Now back to tweaking those adwords...
