Platform ROAS vs. contribution margin: which number should run your budget?
Platform ROAS ignores cost of goods, shipping and processing fees. Here's how to build a contribution margin number that actually tells you which campaigns…

Google Shopping isn’t won on price alone — feed quality and structured attributes decide which queries you’re even eligible for. Here’s how to win clicks without discounting deeper.
The short version
It’s easy to assume Shopping ads are won purely on price — the listing with the lowest number wins the click.
In practice, price is one input among several, and stores that compete only on price are leaving the other
levers on the table.
Feed quality, title relevance, image clarity and structured product attributes all influence which queries a
listing becomes eligible for in the first place — and eligibility for the right query often matters more than
being the cheapest option in a broad one.
A generic, template-generated title (“Blue T-Shirt — Size M”) competes for broad, expensive queries. A title built
around how buyers actually search — brand, product type, key attribute, size — becomes eligible for narrower,
higher-intent searches where competition and cost per click are both lower.
Segmenting campaigns by margin — rather than running the whole catalog under one bidding strategy — makes it
possible to bid aggressively on high-margin products and conservatively on thin-margin ones, without discounting
either.
The listing that wins the click isn't always the cheapest — it's the one that looks like exactly what was searched for.

Promotions and free shipping thresholds, surfaced directly in the Shopping listing itself, often move
click-through rate more than a price cut does — because they’re visible at the moment of comparison, not buried
on the landing page.
Both matter, but feed quality determines eligibility for the right queries in the first place. A great price on a poorly-matched listing simply won’t show for the searches that would convert best.
Monthly at minimum, and immediately after any catalog, pricing or platform migration — those are the moments feed issues most often get introduced unnoticed.
Fixing disapproved and limited items in Merchant Center Diagnostics, almost always. It’s common for a meaningful share of a catalog to be quietly ineligible before anyone looks.
Discounting is the slowest, most expensive way to win a Shopping click. Feed quality, structured attributes and
margin-segmented bidding move faster and protect the margin a discount would otherwise give away.
