In the world of affiliate marketing, an advertiser can be a company or person selling a product/service or looking for leads in a particular niche. Becoming an advertiser means you are ready to pay other people to help you sell and promote your business.
A publisher is an individual or company that promotes an advertiser’s product or service in exchange for earning a commission. Advertisers contractually agree to work with a publisher. You advertise in the form of links, banner or text ads or even unique phone numbers – that the publisher incorporates into their website.
