At the time of the keyword research, I used the Google keyword planner for my keyword research. It does the job, even though it is slow for intensive keyword research. For the Long Tail Pro users,, I think the Keyword Competitiveness (the “KC”) number was about 32 – 34 back in July for the primary keyword. The KC is higher the last time I checked about 34 – 36. (I do use Long Tail Pro now. I highly recommend it since it’s the standard tool for keyword research. Click here for a free trial via this affiliate link.)
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
