Price Mismatch Checker: does your page agree with its own structured data?
Paste a product page URL. We read the price your page publishes in its structured data, then independently check whether that price is visibly on the page right now. Ten seconds, no signup, and the verdict is signed so anyone can verify it.
One difference, stated plainly: we fetch server-rendered content; Googlebot also renders JavaScript. A page we cannot read may still read fine to Google, and the reverse. Unverifiable means we could not confirm it, nothing more.
How this check works.
Google Merchant Center compares three sources for every product: the submitted feed price, the visible page price, and the page's structured data. When they disagree, its documentation describes item disapprovals for price mismatch, and repeated mismatches can affect the whole account. This tool reads one of those three sources, the structured data, and independently verifies whether its price is visibly on the page right now, from our own infrastructure, with an ed25519-signed verdict anyone can verify offline. It answers one narrow question honestly rather than predicting anything.
Questions, answered plainly.
- Does this predict whether Google will disapprove my product?
- No. We never predict or diagnose Google's decisions. This tool answers one narrow question: does your page's structured data price appear on the visible page right now? That is the mismatch class Merchant Center's documentation describes. What Google decides is Google's.
- What does unverifiable mean?
- That we could not independently confirm the answer. We fetch server-rendered content; Googlebot also renders JavaScript, so a page we cannot read may still read fine to Google. We say unverifiable instead of guessing.
- What is a signed verdict?
- Every result is signed with ed25519 and verifies offline against our published key, and its issuance is confirmable at the verdict link. You do not have to trust this site to rely on the answer.
- Is it really free?
- The first 100 checks per visitor are free and rate limited. No signup, no account, no cookies. Checking a page with no structured data costs nothing at all.
- I need more than one page checked.
- That is the Dataset Audit below: up to 5,000 rows against their live source pages, a signed verdict for every row, delivered within 72 hours of receiving your data.
Checking one page found you here. Checking your whole export is the product.
Dataset Audit: $500 flat.
You bought or scraped a dataset. Before you act on it, resell it, or load it, we answer one question per row: is this value actually on its source page, right now? Send up to 5,000 rows with source URLs. Within 72 hours of receiving your data you get a signed verdict for every row: pass, fail, or unverifiable, with evidence excerpts and a summary of what deserves a human look. Every verdict verifies offline; you, your customer, or a counterparty can check any row without trusting us. Scope, stated plainly: server-rendered pages; rows we cannot independently confirm come back unverifiable, never guessed. $250 to begin, the balance with your report. If our fit check finds your data won't verify well, we tell you and refund in full.
After payment, email your export to sales@fieldmodesolutions.com to start the clock. Questions first? Same address.
