Your product feed says size M. Does the link open size S?

The feed says size M. The product page opens with size S selected. The shirt looks identical, so the mistake can survive a quick visual check.

Before changing a price or marking a row as ready, establish which variant the row represents and what its exact submitted URL opens.

A small mismatch that changes the whole comparison

A page showing the right style is not enough to establish a variant match. Google recommends linking to the page with the correct variant already selected. Size and colour information should still be supplied in their appropriate product-data attributes.

A five-minute check for one row

  1. Start from the exported row. Record its ID, intended size, colour and market. Copy the exact link from that row; do not find a similar product through the store navigation.
  2. Open a fresh browser session. Note the option selected before touching the page. A remembered choice from an earlier visit can disguise a bad default.
  3. Check the merchant's source record. Confirm that the row really is meant to describe size M. A familiar filename or image is not proof.
  4. Correct the cause. If the source confirms M, use the store's supported link that opens M. If the row itself describes the wrong variant, correct the source mapping instead. Do not invent a URL parameter and assume the store honours it.
  5. Retest the exact link. Check the selected variant and then its current price and availability. Save the evidence and the time checked.

Choose the next check from what you actually observed

  • The link opens the wrong size: follow the exact-variant URL checklist. Keep the original link and the selected option in your notes before changing a mapping.
  • The correct size opens, but stock differs: use the availability-mismatch walkthrough. Compare the same variant and observation time; another size being in stock does not establish that this one is available.

Both guides are free. A difference is a reason to investigate the current source, not proof that either the file or the page should be overwritten.

What if the store cannot preselect a variant?

Keep that item unresolved and ask the store owner or developer how that storefront supports variant links. Replacing the feed's size with whatever loads first can make the fields look consistent while changing which product is being advertised.

This checklist is practical guidance, not a claim that every step is performed by our free check. Our paid audit has a defined scope, and sampled URLs cannot prove that every page in a catalogue matches. Supported CSV corrections do not edit a live storefront or guarantee platform approval.

Start small: run a free product-page check and review the service scope.
