To find quality publishers, you can search online for reviews and ratings of different publishers. You can also ask other authors or industry professionals for their recommendations. Additionally, you can attend book fairs and conferences to meet with publishers and get a better sense of their quality.
The best way to work with qualified affiliate publishers is to hire an affiliate marketing agency that works with all the networks. The networks provide access to affiliates who’ve been rigorously vetted and had to go through a long application process to be included in the network.
Rather than working with only one of the networks, leave the recruiting of affiliates to us. We have years of data and expertise on our side which will make it much easier to match you with the right affiliates, instead of having to play the guessing game.
