Many SEO and image apps run an 'autopilot' or bulk optimize on first install that can rewrite meta titles, descriptions, tags and alt text across hundreds of products at once. Shopify keeps no version history for these fields, so there is no native undo and no record of what they said before. Backing up first is the only way to guarantee you can get your original values back if the app's first run is not what you wanted.
If you didn't already have a backup, those old values are gone β Shopify keeps no history.
The steps below recover what you can. To make the next time a 1-click undo instead of hours of CSV work: a daily snapshot of every SEO field. Free to monitor, no card β and SEO Vault only reads your store unless you click restore.
