The ads in affiliate programs are linked to company websites and are referred to as affiliate links. Affiliates generally have to apply for the affiliate programs, though the majority of the affiliate programs cost nothing to join. When an online visitor click the affiliate link, the visitor is redirected to the advertiser's website and if the customer/visitor makes a purchase, the affiliate is then paid a commission.
I have been using US Marketing Group for approx. 4 years for both Residential & Commercial Leads and it is mainly because of one of their Sale Representatives, Reggie, which is one of the most courteous, professional & hard working sales representatives that I have spoken to in quite some time as I am a long-time Manager of several previous Call Center Companies and have been dealing with the public on a regular basis as I was also an Advertising Director for a Computer Association and have worked with many SMB VARs (Value-added Resellers) as well as Business Service Providers like Avis...Distributors like CDW...and Manufacturers like IBM.
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.
