You open the Breadcrumbs report in Google Search Console expecting a number close to your product count, and a store with several thousand products shows only a few hundred validated breadcrumbs. The number also moves from week to week even though your catalogue hasn’t changed.
That number measures how much of your store Google has crawled, not whether your markup is right. Breadcrumbs Uncomplicated emits valid structured data on every collection and product page; whether Google has got around to reading each page yet is a separate question.
Check one page, not the total
Google publishes a free tool that reads the structured data from a single page and tells you whether the breadcrumb is valid: the Rich Results Test.
Paste in one product or collection web address from your store and run it. If that page reports a valid breadcrumb, the markup is correct - and because Breadcrumbs Uncomplicated generates it the same way on every page, it’s correct across the whole store. One passing page tells you more than the total ever will.
Why the number moves
Search Console reports with a delay, and Google re-crawls pages on its own schedule rather than all at once. The validated count climbs as Google indexes more of your pages and dips when it re-checks ones it has already seen, but none of that movement reflects a change in your breadcrumbs.
As long as your menu structure stays consistent or grows, the count settles upward over time. Refreshing categories in the app whenever you change your navigation is exactly the right habit - it keeps the trail accurate for the moment Google next looks. The pace of that looking is Google’s to set.
“It says relative URLs, or a missing URL - is that a fault?”
Two readings in a raw view of the structured data look alarming but are both fine.
You may see each step written as a path like /collections/shop-bath-beauty rather than a full https:// web address, but Google’s breadcrumb guidance doesn’t require the full form, and the test that settles it is the Rich Results Test verdict, not how the path looks in the source. Run your own page through it and the breadcrumb comes back valid.
On a product page the final step is the product itself, listed by name without its own link, but that isn’t missing data. Google’s guidance is explicit that the last item in a trail doesn’t need its own address, and that Google uses the page’s own address for it. The collection above the product carries its address as normal, and the product’s own details live in the product’s structured data, which your theme already provides.
Getting more pages validated
More validated breadcrumbs comes down to more indexed pages, which is a question of indexing rather than of the breadcrumb. Keep your structure clean, submit your sitemap in Search Console, and build inbound links to your products and collections. The more of your store Google indexes, the more breadcrumbs it validates - and the trail is already correct and waiting on every one of those pages.
Summary
The validated-breadcrumb count in Google Search Console tracks Google’s crawl, not the quality of your markup. Run one web address through the Rich Results Test: if it passes, Breadcrumbs Uncomplicated is emitting a valid trail on every page. Keep refreshing categories when your menu changes, and the number climbs as Google catches up.
