Q: Where can I find non-spammy affiliates that aren’t just running coupon sites?
A: Without revealing your affiliate program, I see that you are running it through an affiliate network, and they offer lots of opportunities for enhanced placement and exposure of your affiliate program.
Check with your representative at the affiliate network about opportunities there.
Also, have a look around at who is promoting your competition on paid search and Facebook ads. Reach out to those affiliates if they are driving the traffic to their own sites, rather than directly to the merchant.
Another approach, which I did years ago to recruit quality affiliates, was to send out direct mail pieces.
I would research sites that made sense for my niche, and then pull together a database to contact those sites. Then I would have a postcard made with 3-5 value propositions for the affiliate program.
And then you’ve got your customers. Many are likely already unpaid evangelists for your company, because they like what you are doing. Harness their satisfaction and work on scaling up their voices.
Finally, I would suggest looking into conferences, where you can meet up with large volumes of affiliates in person.
I am not objective on this one, since I am a Co-Founder of Affiliate Summit, but each of the twice yearly conferences provide you a chance to meet more than 1,000 affiliates over three days – way more than you have time to meet.
