Kindle books enrolled in KDP Select can be advertised on Amazon via AMS through KDP.

There have always been two targeting choices:

  • product targeting. Select specific products to target.
  • interest targeting. Select a category to target.

Until now, the category choices for interest targeting were very broad.

But now, after you select a category, you can select a subcategory.

Some of the subcategories are still themselves quite broad.

  • For example, for a math or science book, I must choose the category called Other.
  • Then the appropriate subcategory is Math and Science. But that includes very many different subjects.
  • It would be better if the subcategories were further divided. For example, I might choose astronomy, if available.

However, it is an improvement. Interest targeting is better now. It’s a nice step in the right direction.

If you want more precise targeting, the obvious solution is to choose product targeting instead.


  • I used to recommend product targeting. I still favor that, but I just tested out the refined interest targeting so that I can compare. It has some merit.
  • Set the end date as far in advance as possible. It lets you go about six months ahead.
  • Choose to display your ad as quickly as possible. Generally, it’s not easy to make impressions unless you overbid. This option helps if you bid reasonably.
  • Make a catchy headline that’s likely to help create interest in your book, and which is quite relevant for your content.
  • Bid low to begin with. It’s okay to underbid.
  • Wait 3 days before raising your bid. Sometimes reporting is significantly delayed. See how it’s going before you ‘fix’ it.
  • Try expanding your targeting before raising your bid to see if that helps make more impressions.
  • If you do raise your bid, just raise it a little. And wait 3 more days before raising it again.
  • You’re not obligated to invest the whole $100. You can pause or terminate your ad at any time.

With my strategy, I have several affordable bids. Sometimes, I’m able to generate 100,000 to 400,000 impressions in one month with less than $10 spent. I have multiple ads where I spent about $12 to generate $24 in sales (at 70% royalty).

I observe some nice indirect effects on similar books and on my print books. (I tend to sell more print books to begin with, so that makes sense for my books.)

Write happy, be happy. 🙂

  1. Thanks for sharing! That’s already a big improvement. An even greater one would be the ability to edit the details of an expired promo, then rerun it. The fact that you have to set up each promo from scratch is quite the time waster!
