Amazon Ads: Auto vs. Manual?

Start with auto campaigns for data discovery, then graduate to manual campaigns for precision. This is not optional advice. It is the sequence that works.

An automatic campaign lets Amazon's algorithm decide which search terms to show your book for. You set a daily budget, write some ad copy, and Amazon does the targeting. The purpose of an auto campaign is not to generate profit. It is to generate data. Amazon will show your book to a wide range of searches and report back which keywords actually converted into sales. This information is gold, and you cannot get it any other way.

Run your auto campaign for two to four weeks with a modest budget of five to ten dollars per day. Then pull the search term report from your advertising dashboard. You will see a list of every keyword that triggered your ad, along with the impressions, clicks, and sales for each one. Some of these keywords will surprise you. Readers might be finding your book through search terms you never would have guessed.

Now take the keywords that actually resulted in sales and move them into a manual campaign. A manual campaign gives you precise control over which keywords you bid on and how much you pay per click. Set your bids based on what the data tells you about conversion rates. If a keyword converts at 10% and you earn $3 per sale, you can afford to pay up to $0.30 per click and break even. Anything below that is profit.

The mistake most authors make is skipping the auto phase and going straight to manual with guesses about which keywords will work. This is like trying to hit a target in the dark. Let the auto campaign turn on the lights first, then aim.

There is also a category targeting option within Amazon Ads that many authors overlook. Instead of targeting keywords, you target specific competitor books or categories. This puts your ad on the product pages of similar books, catching readers who are already shopping in your niche. Category targeting tends to have lower click-through rates but higher conversion rates, because the reader is already deep in a buying mindset when they see your ad. Test it alongside your keyword campaigns and compare the ACoS.

One more detail: keep your auto campaign running even after you set up manual campaigns. The auto campaign will continue to discover new keywords that you can periodically harvest and add to your manual targeting. Think of auto as your scout and manual as your sniper. You need both.

A common mistake with Amazon Ads is treating them as a set-and-forget system. They are not. Check your campaign performance at least weekly. Pause keywords that are spending but not converting. Increase bids on keywords that are converting well but not getting enough impressions. Add negative keywords to prevent your ad from showing for irrelevant searches. This ongoing optimization is what separates profitable campaigns from money pits. Budget fifteen minutes per week for ad maintenance. It is some of the highest-return time you will spend in your business.
