There is a myth circulating through the BHW community that certain affiliates may not be getting proper credit for their sales or that clickbank vendors might even be intentionally "stealing" their commissions" by overwriting their cookies in their follow up newsletters and emails. Although I was shocked when I first heard this, I am here to inform you that there are indeed a few unethical product owners out there, trying to do everything in their power to bypass paying commissions to their affiliates. Ultimately, this will be their demise. One reason that some affiliates think they're losing commissions is when a clickbank vendor uses pop ups (or pop overs, drop downs, fly ins, etc). Some vendors collect email addresses using a pop over. Once someone opts-in, they begin receiving a autoresponder series and a follow-up newsletter. Unfortunately, some affiliates think that these follow up messages somehow "erase" their clickbank cookies so they don't get credit. The answer is YES and NO. It depends if the vendor is trustworthy. Naturally, every affiliate wants to be assured that they are getting proper credit for the sales that they referred. I understand this completely. How The Clickbank system of cookies and hoplinks works to track your sales If you're not familiar with cookies (clickbank tracking cookies, not the kind you eat!), or if you don't understand how clickbank cookies work to keep track of your sales, then you'll want to read this very carefully. A cookie is simply a little text file that remembers where a visitor came from. When you send a visitor through your correctly coded clickbank hoplink to the vendor's landing page, the moment they land on the webpage, a cookie is dropped on the visitor's machine. This is how clickbank tracks your commissions. It's also the same type of technology that is used by companies like Amazon.com when you land on their site and it says, "Hi Tom, welcome back!" The site can even suggests books you might like based on your past purchases. How is the Amazon website so "smart" that it knows who you are??? Cookies. Just like Amazon "remembers you" when you come back to their site (as long as the Amazon cookie is still on your machine), Clickbank is supposed to remembers the people you send to the vendor's landing page when they come back, as long as the cookie with your clickbank affiliate name is still on their machine. Here is a way to determine if the vendor is trustworthy if he has a pop-up email opt-in form: Sign up for any free reports or giveaways through your own affiliate link and wait for any subsequent email from the vendor. Once you get the email, click link then click on order link. When the clickbank order page opens check the bottom to see who is the registered affiliate. If the vendor is trustworthy then your affiliate ID should show up. If not then he's overwriting your cookie with his and stealing your commissions. In general people don't buy on the first visit to the vendor's page. They usually buy after several follow-ups by the vendor. This is where vendor trust is important. Here's another important fact that every affiliate should know: Clickbanks cookies last for 60 days. This means that if a visitor referred through your hoplink does not purchase the ebook on their first visit, but they come back within 60 days and purchase at that time. YOU WILL STILL GET COMMISSION FOR THE SALE! Now, it's true that there are ways a cookie can be erased, such as when a user intentionally clears the cookies from their hard drive or when their cookies are not turned on at all (there are scripts affiliates can use to identify when cookies are off, by the way - visit forums like the clickbank success forum or the internet marketing warriors forum and ask around if you are interested). Your cookie can also be overwritten if the prospective buyer clicks through another affiliate's hoplink (that's clickbank's policy - last click-through gets credit for the sale - and it's a fair policy). Marketing expert Jay Conrad Levinson, author of the Guerilla Marketing series of books, says that it takes an average of 6 follow up messages before a prospect trusts you enough to purchase from you. As an affiliate, it makes sense for you to associate with product vendors who know this and who have an excellent, tested and proven follow up system. By having a good follow up system in place, you increase the odds that the visitors you send to a vendor's website will purchase within the 60 day cookie window if they don't purchase on their first visit.
