Just found the Plentyoffish Ad Network Blog.
Sampling of posts:
“Onto business! We’re no longer allowing Eharmony to be advertised. Sorry guys!”
“A great case study on POF’s conversion tracking”
“Unfortunately going forward Plentyoffish won’t be accepting ads promoting Singlesnet or any of its brand extensions.”
There are some good posts about how the POF ad system works and best practices. If you advertise on POF (and who doesn’t in the dating space?), check it out.
