Not much has changed here since we last chatted, but when the issue of using affiliate links in YouTube was brought up most recently, we got in touch with Amazon to see if we could find any answers. Even over chat, this topic evoked mysterious responses. However, the overall sense we got was that it is acceptable to use Amazon affiliate links on YouTube.
Leadpages claims that its affiliate program is not exclusively for affiliate marketers, which is true, but the narrow focus of this niche means that only professionals affiliate marketers will ever be able to earn significant income from the program. Leadpages’s affiliate program does offer quite a lot of different options (webinars, videos, blog posts, free marketing courses, etc.) to send referrals to, which can lead to higher conversion rates if done correctly.
The bulk of the offers that I promote pay around $20-$40 per lead, but there are others that pay more and less. However, you don't want to get caught up solely on what an offer pays because how well it converts is just as important. For example, if you have an offer that pays $9, but if it converts at 2X or more of a $20 offer, then it will perform about the same and possibly better. At the same time, if you have an offer that pays $90 and it converts poorly, it may not even be worth promoting.
