JVZoo lets you both host and create landing pages on their own website, so it’s far better suited for professional marketers who want to flood the internet with offers, many of them for courses to make money. You don’t need your own website to participate in JVZoo, but you will need to know how to drive traffic to a landing or squeeze page in order to profit from being a JVZoo affiliate.
Wealthy Affiliate is also very strict on spam, which in the end is a GOOD thing, but I have to be careful sometimes about promoting my sites or referencing them. Sometimes I do have valuable information on my site that I think could help people during live chat sessions or Q&A’s, but I don’t share because I don’t want it to look like I’m spamming. They do allow people to promote their sites in certain areas, but in order to keep the community from filling up with self-promotion spam, there are times when it is best not to share certain information from outside sources, especially my own sites.
