I have been working with Edugram for a little less than a year under the Author24 offer, I have educational sites, so this affiliate program is the best fit. Team representatives are constantly improving offers, trying something new, taking into account the opinions of webmasters. Payments are always made on time within the time limits stipulated in the terms. Of all the partner programs that have been tried in addition to AdSense, I think this is the best. The only thing is that not all offers went in, for example, there were few confirmed applications for online schools, so I left one Author24.
