Good point about reviewing online courses before you promote them to protect your reputation. However, I would like to point out that the level of attention the course creator gives you (the endorser) and what they give to a random customer might be very different. There are so called marketing gurus out there who are extremely skilled at making false promises and not delivering on them. Once they have the endorsement of a few reputed marketers and some ‘lucky’ customers, they can easily get away with ripping other people off with hyped up money making guarantees. I have had a personal experience with this as a customer, but lets not mention names! The point is, when we are promoting someone, we need to do an in-depth due diligence. Only going through their course is not enough. It would be great if there was some kind of a course review site -something like tripadvisor. This is something that the industry really needs – something to make people accountable. A lot of people are losing faith in these online courses. I am staying away from promoting people unless I am very certain of their integrity.
If you have pop-ups and optins on every page, I would have to think that it would be a lot harder to convince someone to link to it. Especially since the pages where you have your optins (and probably receive the most traffic) are probably the same pages that you have your best content on as well that you'd be hoping to pitch in your outreach campaign.
