Last year, I added Amazon affiliate links to my blog and podcast for books I shared (see here). Affiliate programs are commission programs. For every person I refer to Amazon who purchases the item I recommended, I get a commission on the sale. These programs didn’t interest me initially. For books, the effort exceeds the reward. Affiliates earn roughly $0.50 on a book sale. But then I realized the true value is in the data. Amazon’s affiliate program is robust, and I can track which books people click on and which books they purchase. I was very interested in the data, so I signed up for the program and started using affiliate links in mid-June 2024.

I have roughly six months of data. Here are the high-level stats:

• Items purchased: 14
• Total revenue generated (for Amazon): $226.05
• Average revenue per item (for Amazon): $16.14
• Total affiliate earnings (for me): $6.17
• Average earnings per purchase (for me): $0.44

I earned about $1 a month from affiliate commissions. My time to implement and execute this was worth more than $6, lol.

But I dug into the data and had some interesting insights:

• No book had more than one affiliate purchase.
• The books purchased were mostly about investors who became entrepreneurs when they founded investment firms: Jim Simons, Ed Thorpe, etc. This was interesting and unexpected.
• I had three international sales in Germany and the United Kingdom. I didn’t expect to have international reach.
• The majority of purchases were of Kindle or audiobook versions. I’m a physical-book person, so this surprised me.

Absent this affiliate experiment, I wouldn’t have known any of these things. So, from an insights perspective, the experiment was valuable. The sample size is small, of course, so I can’t draw definitive conclusions, but it’s still helpful.

So, what’s the verdict on my Amazon affiliate experiment? I’m glad I did the experiment because of the data it provides. I won’t get rich off affiliate commissions on book sales, but the insights are valuable. Now that I’ve got this, stopping the experiment doesn’t make sense. I’ll keep adding the affiliate links to content I share about books.
