Hi, just to let you know that I had a conversation with customer service at Amazon.com and they only allow direct links to Facebook, Twitter and Youtube at the moment and I asked about Pinterest and the answer is no you can’t link directly to an Amazon product, you need to go via your own website or blog. If they catch you doing that, your account will be closed as it is against their TOS.
Even though Walmart.com’s cookie life is significantly longer, my analysis shows that over 85% of sales (in programs with cookie life equal to 90 days or longer) occur on the first day. So even with their dismal 24 hours cookies Amazon.com’s affiliate/associates program looks significantly more attractive to affiliates (more SKUs, better affiliate tools, higher earning potential due to the obvious differences in commissions as well as some of the things not mentioned above, but listed in the affiliate feedback below).
I was interested in joining the Amazon associate program but the update rolled out. I haven’t started work as an Amazon affiliate so I was just curious to ask that is it fine if we send traffic only from social media platforms? Does Amazon allow only social traffic like Pinterest, Instagram? Will it result in a ban if we don’t add much content rather make it look like an e-commerce store?

Facebook can be tricky. Its terms change frequently regarding promoted and branded content, especially as the new forms of branded and sponsored content become popular, which affects the way in which you can use Amazon affiliate links without getting into trouble with Facebook. Your understanding of the process and the important steps to take to stay within Facebook and Amazon guidelines will help your money-making abilities.

          The quality of your photos can make or break your pin’s success. As new bloggers, we’re all cash-strapped, this is one area where you can’t be cheap. Don’t underestimate the power of professional quality images! I use Deposit Photos to source all my images for pins. Typically, I’ll search for images like “feminine computer desk” or “workspace with flowers.”
This is undoubtedly the best part of Amazon’s affiliate offer. In other programs, if a shopper clicks your link for one product but goes on to buy something else, you get nothing. With Amazon, anything the user buys when they reach the site after you refer them will earn you a commission. You could refer them to a $10 book and if they remember they wanted to buy a $1,000 TV; you get the commission on the TV as well.
