I use Builderall and it has been the easiest to sell due to all the value they provide. very user-friendly and provide ALL online marketing tools from making Websites, Webinars, Animated Videos, etc + having an Affiliate Program that makes you earn a lot quicker due to their Tier 2 program.
Regarding techniques, definitely using social media, posting content/value (the Builderall platform provides you with high-quality content you can post from pictures to videos)
The Builderall platform provides video tutorials as well so seriously the platform answers all of the questions regarding Affiliate Marketing/Make Money Online and the important questions: HOW through videos
Their Affiliate Program as I mentioned above is one of the BEST, if you know the cosmetic brand Oriflame (you can read about it and how to make money with it to understand) they do the same it's only these two brands that I've seen that do Affiliate Program like this where anybody can get in and make money and get out of the stressful financial struggles.
