The seller, whether a solo entrepreneur or large enterprise, is a vendor, merchant, product creator, or retailer with a product to market. The product can be a physical object, like household goods, or a service, like makeup tutorials. Also known as the brand, the seller does not need to be actively involved in the marketing, but they may also be the advertiser and profit from the revenue sharing associated with affiliate marketing.
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.
