Disapproved products don't show ads, and you rarely find out until the budget is gone. Kernvel Product Feed Audit checks every active product against Google Merchant Center and Meta catalog rules, then hands you a prioritized fix list — before the platforms start rejecting.
A missing GTIN, an ALL-CAPS title, or a broken availability flag quietly disapproves a product. Your ads simply stop showing for it — no alarm, no email, just lost sales.
Products that squeak through with thin titles, single images, or missing apparel attributes get fewer impressions and worse placement. You pay the same money for weaker results.
Google's and Meta's specs are long, different from each other, and change. Checking hundreds of products by hand is a day of work the audit does in one click.
Best for merchants running Google Shopping or Meta catalog ads. Every feature below ships in the free app — there are no paid tiers.
Every active product checked against 33 rules — titles, descriptions, images, price and availability sanity, identifiers, apparel attributes, and category mapping.
A single 0–100 score with a letter grade, weighted by severity, so you always know where the catalog stands — and the score is withheld rather than shown wrong if a scan can't finish.
Separate sub-scores and findings for each platform. Sell on one only? Tell the app and the other platform's rules stop counting against you.
Findings clustered by severity and rule, each linking straight to the product in your Shopify admin. Snooze what you're not acting on; export any list to CSV.
GTINs are validated with GS1 check-digit math, length rules, and catalog-wide duplicate detection — and if your products legitimately have no GTINs, one setting makes the score reflect that.
Score history, fixed-vs-new deltas between scans, a most-common-issues leaderboard, and an optional weekly email with your score and top fixes.
One click starts a full catalog scan — no configuration required, nothing to map, nothing to upload.
Start at the top: the highest-impact problems come first, each with the exact platform rule behind it and a direct link to fix the product.
Watch the score climb, see what got fixed versus what's new, and let the optional weekly digest keep the feed honest.
No plans, no feature gates, no surprise charges. These tools are how we earn trust with merchants — and every one includes a free concierge setup call with our team.
No subscription, no usage caps, no premium tier hiding the good parts. The app you install is the whole app.
Rule-based and deterministic — no AI black boxes. You can always see exactly why the app did what it did.
No shopper profiling, aggregate-only counters, minimal Shopify permissions, and data that cleans up after itself.
No. The app is strictly read-only — it holds only the read-products permission and never writes anything to your store. Every fix is made by you, in your admin, with the app pointing the way.
No. Every check is a deterministic rule that cites the Google or Meta requirement behind it. Same catalog in, same findings out — no guessing, no hallucinated advice.
Set your feed focus and the other platform's rules stop running entirely — your score reflects the platform you actually use.
Everything. Full catalog scans, the score, trends, CSV export, the weekly digest — there are no plans, no limits, and no upsell tiers inside the app.
Every Kernvel Free Tool comes with a free concierge setup — a 15-minute call where our team configures the app for your store. That's the whole pitch: useful tools, set up properly, no invoice.
