What it is
Your product page carries two copies of the same facts. One is the price and rating a shopper sees on screen. The other is that information written into structured data, a machine-readable block that AI assistants and search engines read. When the two match, a machine reading the hidden copy describes your product correctly. When they drift apart, the price in the code says one thing while the page shows another.
How common it is
About two in three audited stores (68%) keep their numbers in agreement. The audit reads the structured data on the page and compares it against what is visible, checking that the price in the code matches the price shown and that the review count lines up. A mismatch usually creeps in over time: a price changes on the page but the structured data is generated separately and keeps the old number, or a plugin writes a rating that no longer matches the live one.
Why it costs you
An AI assistant trusts the structured data because it is written to be read by a machine. If that copy says one price and your page shows another, two things go wrong. The assistant may quote a shopper the stale price from the code, so the customer arrives expecting it and feels misled when the total is higher. Worse, a system that reads the structured data may repeat the wrong number, while one that checks it against the page sees a contradiction it cannot resolve. Either way, your product is described wrongly. A wrong price is more dangerous than a missing one, because it actively makes a promise you will not keep.
What good looks like
The structured data should be generated from the same source as the visible page, so a price change updates both at once and they can never disagree. The figures a machine reads, price, availability, and review count, should always equal the figures a shopper reads. The aim is one set of facts about the product, told the same way to people and to machines.
Check it in 30 seconds
Paste a product URL into Google’s Rich Results Test and compare the price and review count it pulls from the structured data against what the live page shows. If the numbers differ, your hidden copy is telling machines something your page does not.
