A big catalogue, read whole. Including the part that never shows.
Marketplaces advertise more products than anyone can check by hand. Oppy reads the catalogue against the spend: what never got an impression, what the listing groups shut out, and which searches ask for things nobody sells.
- Whole-catalogue checks
- Searches added up by theme
- Performance Max read by channel

Problems that only appear at scale.
The silent catalogue
Most of a large catalogue never earns an impression. Some is discontinued, some overpriced, some the next best seller. Oppy counts it, so you can decide which is which.
Small searches, large total
Thousands of searches for things the products never mention, each too small to notice. Added up by theme, they are a share of the budget.
Search and Performance Max overlap
Performance Max takes queries your Search campaigns already bid on, and the credit moves with them.

The part of the catalogue that got no impression lately
The share of the catalogue that got no impression lately. Reported as a fact: some is discontinued, some overpriced, some the next thing to sell.
The part of the catalogue that got no impression lately: How it decides and what to doA listing group shutting most of the catalogue out
A listing group that shuts most of the catalogue out. A product excluded from every group can never show, whatever its margin.
A listing group shutting most of the catalogue out: How it decides and what to doProducts held back by something in the feed
Products limited by an error or a warning in the feed, such as a missing colour, gender or age group. They still sell, in fewer places, and the regions affected are named.

Performance Max matching queries your Search campaigns already bid on. The credit moves to Performance Max, and Search looks worse for work it used to do.
Performance Max buying queries the Search campaigns already bid on: How it decides and what to doSearches that already make money and have no keyword of their own
Searches that already convert with no keyword of their own, read over a long period so a search that converts now and then still counts. The one check that says the account is missing something.
Searches that already make money and have no keyword of their own: How it decides and what to doA negative keyword switching off one you chose
A negative keyword that switches off a keyword you chose. The keyword still says enabled and still shows a Quality Score, and its own searches never reach it. Checked against every negative in force.
A negative keyword switching off one you chose: How it decides and what to doThe same keyword bidding against itself in two campaigns
The same keyword live in two campaigns, so the account competes with itself for the same search and the reporting splits it between two places.

Spend
Where the money goes
Spend piled into a handful of products
Spend piled into a few products, usually the cheapest ones, because a low price wins more auctions. Shows where the money went and what came back.

Small searches for things the products never mention, added up by theme. Each search is too small to notice; together they are a share of the spend.

The share of spend on searches nobody added or excluded, the ones Google matched on its own. Not waste in itself: one percentage to watch month to month.

Search terms by the thousand. Judged one by one, decided in a few tasks.
A marketplace's search terms report can run to tens of thousands of rows. Oppy reads all of it against your own conversion rate, groups what wastes money by theme, and proposes negatives campaign by campaign.
Never block what converted
A search that converted in any ad group is never proposed as a negative.
Plurals included
A negative that lets its plural through is found, with the plural proposed beside it.
Winners harvested
Searches that already sell and have no keyword of their own are proposed as keywords.
Questions from marketplaces.
Anything else? Ask Oppy in the product, or write to the team.
Can Oppy handle a catalogue with tens of thousands of products?
Yes. Feed and catalogue checks read product status and impressions across the whole catalogue, and report totals and the worst cases rather than a list nobody can read.
Does Oppy work with many campaigns and categories?
Yes. Checks read every campaign. When a finding touches hundreds of items, Oppy groups them into a few tasks you can approve at once.
How do you avoid blocking searches that sell?
A search that converted anywhere in the account is never proposed as a negative, and words a buyer could type are asked about before anything is blocked.
