Good revshare percentage?
 

I've been running adult dating sites for the past two years with "OK" results, but looking to make something more off of them as for now I just use organic traffic and AdWords.

I've reached out for some local tubes and websites/forums asking what they'd charge for advertising on their sites, and generally we're talking about 500-1000 euros per month. Being poor 'lil hippie I am dropping that kind of money into something that I have zero clue about ROI-wise seems like a real shot if the dark, so I've asked if some of them would accept into revshare to cut the initial investment. And some have.

Now the actual problem, how much to pay? Or even suggest? Would 20% be laughably little? Obviously making any money without spending it at all is good, but I wouldn't just like to give it off when I could be spending it for booze and hookers myself.

I'd say 30% minimum, but be prepared to go higher.
As they saying goes would you rather have 50% of something or 100% of nothing :-)

500-1000 euros are too much , i know those are some standard offers

better search 4 free/cheap traffic if u can find
