KDP ads getting no impressions: causes and fixes

An ad that isn't showing is usually one of six things. Check them in this order; the first three explain most cases.

By Michael Cortez · Updated November 8, 2026

1. Still in moderation, or rejected

Every new ad is reviewed. Check the ad's status in the console: "pending review" means wait, and a rejection message will say what to change (often cover or copy issues).

2. Bids below the going rate

Amazon runs an auction. If your bid is far under what others pay, you'll rarely win. Compare your bids with the suggested range. If you need to raise them, use the bid calculator to make sure the new bid is still profitable for your series.

3. Keywords too narrow

Exact-match keywords nobody searches won't serve. Run an auto campaign or broad match alongside exact, then read the search term report to find the searches that convert.

4. Budget or schedule

Check the daily budget isn't exhausted early, the campaign isn't paused, and any end date or portfolio budget cap hasn't been reached.

5. Eligibility

Ads only serve for books that can be bought. Look for ineligibility notes on the ad (unavailable format, listing problems, category restrictions).

6. Too many negatives

Aggressive negative phrase keywords can block almost everything. Review your negative keywords for broad words that remove good searches.

Once it's serving

Impressions are the start. Judge the ad on what the clicks earn across the series: sales, Kindle Unlimited page reads and read-through. The Kindle Author Ads Analyzer does that from your search term report.

Questions

How long do new Amazon book ads take to get impressions?

New ads go through moderation first, which can take from a few hours to a few days. After approval, low bids or narrow keywords can still mean slow delivery for a while.

Should I just raise my bid?

Raise it in steps if your bid is well under Amazon's suggested range, but keep it below what a click is worth to your series. A bid you can't afford gets impressions and loses money.

Do ads stop if my book isn't in stock?

Ads need an eligible, buyable product. Paperbacks that show as unavailable, or books with listing problems, may stop serving. Check the ad's status for an eligibility message.
