Where to advertize my affiliate link

I had join an affiliate website, and now i want people to singup for that.

Actually, it for web owners to join the site and run adds . I am not sure how to promote it (donot say me to promote via social media I already doing it).

Actually, I want to know is there any forum blogs where i can advertiser my link for free or for exchange?

It free offer? Any suggestion

I've had a lot of success with sites that use pop-ups to send you traffic. It usually costs about $20 for 5000 visitors. if you have a half decent landing page it is worth a try.

Is it per click or per sale?

I've always had good conversions with bathroom stalls.
