The metrics our Paid Media experts check before adjusting a single bid, and why the order matters…
When a brand’s Amazon Ads performance dips, so many assume that the first lever to pull is bids – and it’s understandable, after all, they’re visible, adjustable and it’s a move that feels decisive.
But, as Elfie Brocklehurst from our award-winning Paid Ads team points out, changing bids before you understand why performance is off rarely fixes the problem, it just masks it.
The real starting point is diagnosis, and that starts with one metric above all the others…
CTR: the metric most Amazon Advertisers undervalue
Most advertisers, Elfie says, are focused on ROAS, but it’s your CTR (click-through rate) that our experts see as the more important signal – and the one that tells you the earliest whether your brand is built to compete on the marketplace, because:
It shows you relevance
A strong CTR means shoppers see your ad and immediately believe it matches their intent; a weak one means you’re either targeting the wrong audience or your creative isn’t earning the click.
And no amount of bid adjustment will fix either of those problems.
It reflects the strength of your creative
Your image, headline, price point, reviews and branding all feed into CTR.
Before assuming a budget or bid issue, the ad itself deserves scrutiny first.
It’s an early predictor of wider performance
Strong CTRs create traffic, and traffic creates sales opportunities.
But if CTR is strong and conversions are still weak, the issue has moved downstream – meaning it’s time to look at the product detail page, not the ad itself.
It affects cost efficiency over time
Higher CTR improves your ad’s engagement signal, which can lead to more efficient CPCs and stronger placement – and compounding the advantage for brands who get it right early.
So what should you do to diagnose the issue before you touch the bid?
CTR is the starting point, but it’s part of a broader diagnostic that Elfie and our experts run before they adjust a single bid – and after you’ve looked at your CTR issues, that sequence looks like this:
Conversion rate
If customers are clicking but not buying, something is breaking between the ad and the purchase.
Whether it’s delivery speed, Buy Box ownership or listing quality, these are conversion problems, not bid problems.
Search terms
Is the traffic actually relevant?
If the algorithm hasn’t correctly understood the SEO, impressions may be building against the wrong searches entirely.
Product-level performance
All too often, one underperforming ASIN is the culprit for skewing results across an entire campaign – identifying it can change your decision entirely.
The Bottom Line
It’s not that bid optimisation doesn’t matter – obviously it does.
But bids applied on top of an undiagnosed problem don’t resolve it, they hide it, often expensively.
Bid strategy is only as effective as the diagnosis behind it.
And that diagnosis almost always starts with CTR; the metric that tells you whether your creative is working, your targeting is right and your brand is genuinely built to compete.
Get it right early, and the rest of the system moves in the right direction. Ignore it in favour of chasing ROAS or pulling bids, and you’re optimising the wrong thing.
For our experts, the strongest Amazon advertising strategies treat media performance as a commercial system where creative, content, availability and spend all interact – and pulling one lever without checking the others is how brands end up investing more for diminishing returns.
