Amazon Ads on launch day — the bid strategy that doesn't burn your budget in 48 hours

The first 96 hours of a book launch are when most authors lose 60% of their ad budget to badly-bid campaigns. Here is the cadence that keeps the spend disciplined and lets the launch compound.

Pre-launch week: warm the algorithm

Three to seven days before launch, build the campaigns. Set conservative bids — 60–70% of your eventual launch-day bid. The point is to give Amazon’s algorithm signal about what you’re targeting before the launch volume hits. Campaigns built on launch day take 48 hours to receive enough impression data to optimize.

Build three campaign types from day one. Sponsored Product (auto + manual keyword), Sponsored Brand (auto + manual ASIN), Sponsored Display (audience + product targeting). Each does different work; together they cover the discovery surfaces a reader could find your book through.

Launch day: bid up

Day 1 of launch: bid up 25–40% over your pre-launch bids. The goal is impression-share on your top 30–50 keywords during the launch-day BSR spike. You want to be visible for any reader who searches your category that day, even if the per-click cost is higher than normal.

Daily budgets day 1: 2–3x your eventual sustain budget. A book that will sustain on $40/day in ads should run $100–$120 on launch day. The reason: launch-day clicks convert at 2–4x the rate of sustain clicks because the BSR is high, the reviews look fresh, and the algorithm is surfacing the book more.

Day 2–3: hold

Hold the elevated bids for 48 more hours. The algorithm is still in its “decide what to do with this book” window. Pulling spend on day 2 signals lack of conviction and Amazon downgrades the title in the surface.

Day 4–7: optimize and tier

By day 4, you have 4 days of click and conversion data. Rank keywords by ACOS:

• Top tier (ACOS under 35%): keep bids high, expand match types
• Middle tier (ACOS 35–60%): hold bids, watch closely
• Bottom tier (ACOS over 60%): cut bids 40% or pause

Most authors discover that 50–70% of their ad spend in days 1–3 went to keywords that will not sustain. That is fine. The disciplined tiering is the point of running launch ads, not the launch ads themselves.

Week 2: stabilize

Days 8–14: campaigns are in sustain mode. Bids 15–25% lower than peak. Daily budgets back to sustain levels ($30–$60 for a typical single-title). Continue tiering weekly.

Add the patterns that worked: Sponsored Brand with the book’s strongest hero asset, Sponsored Display retargeting visitors who didn’t buy.

Week 3–4: scale or hold

Week 3 is the spend decision. If the data shows ROAS above 1.0 on Sponsored Product, increase budget by 20–30%. If ROAS is below 0.7, hold spend flat and refresh creative.

The decision is not binary. About 40% of launches we run move to expanded spend in week 3; about 35% hold flat; about 25% pull back to maintenance mode.

Common mistakes

Bidding on irrelevant keywords. Most authors start with auto-targeting which generates a long list of keywords Amazon thought were relevant. The first cleanup at end of day 1 should remove 20–40 obviously irrelevant terms.

Setting daily budgets too low. A $20/day budget on a serious launch caps you out by 10am most days. Better to run $80/day for 4 days than $20/day for 16 days; the algorithm responds to spend velocity.

Ignoring Sponsored Brand and Sponsored Display. Most first-time advertisers run only Sponsored Product. The other two ad types serve different surfaces in the customer journey and reach incremental readers.

Not refreshing ad copy. Day 1 ad copy that worked in week 1 stops working by week 3. Refresh monthly minimum.

Failing to tier by ACOS. Every keyword gets the same bid forever. This is what burns spend on non-converting terms.

What we run

For full-service launch clients, the launch-day campaigns are built 7 days before launch, validated, and operated daily for the 30-day arc by our team. Reporting every Friday in plain English. ACOS targets disclosed on kickoff. No mark-up on ad spend.
