The problem
Bids drift. Margin goes with them.
The auction moves underneath you: competitors change their bids, new sellers enter, seasonality shifts, your own conversion rate moves. The bid you set last month was priced for conditions that no longer exist.
Hundreds of bids, one of you.
Every keyword moves on its own. Nobody re-prices them all by hand.
Catching up isn't keeping up.
A monthly bid review fixes last month's auction.
What a bid rule can do

Our own account
The strategy we run ourselves.
Three bid rules on an ACoS band, and a fourth for the keywords nobody has seen yet, running every week on our own products. One way to use the builder, not the only one.
One target number makes bids oscillate.
PPC fluctuates on its own. Chase a single ACoS and every wobble becomes a bid change.
Target a range, not a number.
25% becomes a 20 to 30% band, and nothing moves inside it. The band absorbs the noise.
One rule per tier.
All three run weekly, need 15 to 20 clicks since the last adjustment before they act, and never look back more than 30 days, so the data can't go stale. The click threshold follows the product's conversion rate: the higher the CVR, the fewer clicks it takes to judge.
Four tiers. Three rules, one hold.
Under 20%4 of 18Raise 10%
20–30%8 of 18Hold

A fixed window grades the old bid.
Raise a bid and a 30-day window keeps averaging in weeks of data from the old one. It reports a number nothing is actually doing, and you act on it again.
Demo data
A daily run can judge a bid on its worst days.
Change a bid on Thursday and a daily run can have its 20 clicks by Saturday. On a B2B product those days barely convert, so ACoS reads high and the bid is cut 20%, though it was working all week. We run the same three rules weekly instead, so every verdict has the good days in it too.
A rule for the ones nobody saw.
Zero clicks and under 1,000 impressions isn't a losing keyword. It never got enough exposure to prove anything either way. Raise it 20% and look again in a week.

Worked example
What one night looks like.
Six keywords from one campaign, each judged on data since its own last bid change: the tier it landed in, and what happened to its bid. Demo data, real logic.

Amazon finalises sales data about 48 hours late, so bid rules never read the last two days.
