Technical Assignment: Correction of schema.org Microdata for Google Merchant Center
Project Goal
Eliminate product rejections in Google Merchant Center caused by price discrepancies in microdata for the Woocommerce online store
Problem Description
Google Merchant Center rejects products due to the error:
Price in microdata does not match the price on the site and in the feed.
Product example: https://www.prohouse.store/tualetnyj-stolik-model-rd-5299/?attribute_czvet=%D0%A1%D0%B5%D1%80%D1%8B%D0%B9&attribute_komplektacziya=%D0%A2%D1%83%D0%B0%D0%BB%D0%B5%D1%82%D0%BD%D1%8B%D0%B9+%D1%81%D1%82%D0%BE%D0%BB%D0%B8%D0%BA%2B%D0%B7%D0%B5%D1%80%D0%BA%D0%B0%D0%BB%D0%BE%2B%D1%81%D1%82%D1%83%D0%BB+%D0%92&attribute_razmer=80%D1%8576%D1%8540+%D1%81%D0%BC
Google Requirement:
Microdata must contain only one price for each product (without ranges).
What Needs to Be Done
Correct the schema.org markup on product pages:
Remove all mentions of lowPrice, highPrice, AggregateOffer.
Replace with the correct structure using type: Offer and a single price value.
Check all product pages for similar errors.
Ensure data consistency:
Set up validation through Google Rich Results Test.
Here is the response from the representative. Google Merchant Center
After checking your account, we found that the main reason for rejection is the incorrect product price.
For reference, I checked one of the product identifiers:
Price on the landing page - 26,031 UAH.
Price in microdata — lower and higher prices. 8,060 and 29,319
Price in Merchant Center - 26,031 UAH.
According to our policy, prices for products must be the same across all destinations. Please note that the schema may not contain maximum and minimum prices. It should contain only one price for each variant. Please update your schema.
