Most product page problems aren't hard to catch, they're just easy to skip when a new listing is going up in a hurry. None of the checks below take long. The value is in actually running through them every time, not in any one of them being complicated.
- Does the price actually show up on the page, not just in the admin panel
- Does the main image load, and does it show the right product
- Is there a real description, not just a copied spec table
- Does that description belong to this product, not a similar one
- Has anyone actually read the description once, out loud, for typos
Why this order matters
These are roughly ordered by how fast a shopper notices them. Price and image are the first two things anyone sees. Description quality matters once they're actually reading. Spelling is the last thing most people consciously notice, but it's often the detail that quietly confirms whether the rest of the page can be trusted.
For a catalog with more than a handful of products
This checklist works fine by hand for one listing at a time. It stops being realistic once there are dozens or hundreds of products being added or updated regularly, which is the exact gap an automated scan is meant to fill, running the same checks at catalog scale instead of one page at a time.
