Ever wonder why you never seem to sell anything through your affiliate links?  Even when someone clicks on your ad or link, you still don’t get the sale.  I bet you’d like to know why?  The answer is usually cookie stuffing.

Cookie Stuffing is when a malicious website overwrites your affiliate cookie with their cookie, so they get paid the commission for the sale.  It’s against their affiliate Terms of Service, but many affiliate programs don’t aggressively enforce it.

3 simple reasons you are screwed: Consumer Behavior,  Merchant Behavior, and Thieves.

Consumer Behavior:  If you ever bought something online, I know you are all guilty of the following.  You get all the way to the checkout page of a website, see the price for the merchandise, see the price of shipping, and then see an empty box for “coupon code”.  You type into Google “merchant name coupon code”, get the code, try it, and repeat until you get one that works.  Sometimes you will give up and place the order anyway.  Guess what, 99% chance you just robbed an honest affiliate of their commission and gave the money to a criminal.

coupon codeMerchant Behavior:  Merchants are just as guilty.  Most of the merchants that display a box for the coupon code only do so because it came with the merchant software, and they thought it might be cool to offer a code for an upcoming holiday.  Even the merchants that do offer regular codes don’t display them on the page, they hide them in emails or send them to coupon code sites directly.  Guess what, merchant stupidity just eliminated 2% to 20% of their profit.  Many people like to bookmark the merchant directly, and they’d never have to pay an affiliate a commission, except for the fact that they have that burning desire to display that empty coupon box.

Thieves:  Let’s not forget about the people who are robbing both merchant and honest affiliates.  Until these a-holes get dragged into court, they will continue their scam.  How do they do it?  This website is pretty much a how-to site on how thieves do cookie stuffing, it even outs the guilty people.  The usual methods are scripts, 0 sized I-frames, and software programs like toolbars that intercept the browser data.

How to tell?  How do you know if a website is stuffing cookies?  Simply clear all cookies on your browser and then load their site and check all the cookies loaded.  You may see 10-20 cookies being set, but none of them should be for a merchant.  If you see something like bluehostaffiliate=website.com or amazonaffiliate=couponloser, then you have been stuffed.  In essence, simply loading their page acts like you clicked each and every one of their ads.

What can be done?

  1. If you insist on searching for coupon codes, search ahead of time, write the codes down, and then clear your cookies.
  2. Just before purchasing, clear your browser’s cookies and then click on the merchant affiliate link from an honest affiliate.
  3. If you own a website, refuse to run ads for merchants who have a coupon code box at checkout.
  4. Pressure affiliate marketing companies to aggressively pursue cookie stuffers, and come up with alternate ways of recording sales.
  5. If you catch anyone stuffing cookies, report them to the merchant, their affiliate company, and even the FBI for racketeering.  See how ebay recently sued a site for cookie stuffing. 
  6. Run Pay-Per-Lead, Pay-Per-Impression, and Pay-Per-Click ads until the situation improves. 
  7. Share your shopping links with friends, but educate them about cookie stuffing and how to prevent it.
  8. Merchants and affiliates, if you can’t live without the coupon code box, display coupon codes in your ad, or near the ad so people don’t feel the urge to search on the net.

Yes, I know most consumers don’t care about who gets the commission, as long as they get free shipping.  Just remember next time you cry “My blog makes no money,” maybe now you know why.
