What is the Affiliate Finder?

Rewardful has a built-in Affiliate Finder search engine that tries to surface proven affiliates around the web based on queries you run.

To our knowledge, nothing else exists on the market like this.

What is an Affiliate Finder credit?

Rewardful has a built-in Affiliate Finder search engine that tries to surface proven affiliates around the web based on queries you run. A 'credit' is used when you reveal the details for a specific search result. Performing a search doesn't use a credit.

Credits reset to zero every billing cycle and unused credits do not rollover to the next month.

Is the Affiliate Finder similar to an affiliate marketplace? Are you pulling the results from your affiliate database?

No, the Affiliate Finder is very unique in that it crawls the web to find relevant affiliates based on your query. Marketplaces are a passive approach to recruiting affiliates and are often filled with low quality, poorly vetted affiliates that aren't very relevant to your business.

The best affiliates generally don't come inbound. The Affiliate Finder enables you to take control over the success of your affiliate program by actively finding affiliates that are a great fit for your business.
