Is it profitable? If yes, why are you selling it?
How much can someone generate per day if he simply takes over the site, without doing any modifications?
In how much can someone ROI those $500?
Yes, it's profitable. And I am selling because I am very lazy...
And "how much anyone can generate", I can say my own but can't say about others cz I have adsense and some other good adnetworks such as mellowads, cointraffic, coinzilla etc... I generate 20~25$ on average where publishers generate 8~12$...
I think if any good developer take this site and do proper advertising, he will be able to recover 500$ within 1.5~2 months...
