A pleasant educational affiliate program. They customize a lot of promotional material, it's just nice to work like this.
Like:
-a large selection of promos, which is very convenient (as I said),
-high conversion rate (especially in the USA) ,
- the personal manager is almost like a mentor here. helps with choosing a strategy.
Don't like:
- I'm waiting for new offers, it's not enough yet
Everyone has their own, of course, but in order to understand for themselves OK guys or not ok - you need to test. The field for the test is large and there are promo and landing pages. For me, one of the partners in edu niche is edugram topchik
