Shopify collection description disappeared after an app? How to get the category-page text back
An app run (or a theme update) wiped or overwrote the description on your collection pages — the block of text that gave each category page its only real, indexable content — so those pages went thin overnight and started slipping in search. On Shopify the collection description and its SEO meta are single fields with no version history, so there's no native undo and no record of what they said before. And there are two very different causes: sometimes the text was genuinely deleted, sometimes it's still saved but a theme change stopped it rendering — so the first job is telling them apart.
Step by step
First find out whether the text is actually gone or just not showing. In admin open Products > Collections > [your collection] and look at the Description box, then click 'Edit website SEO' to check the meta description too. If the Description box still has your text but the live collection page shows nothing, the data is fine — a theme update changed the collection template so it stopped rendering {{ collection.description }}, and that's a theme fix, not a recovery job. If the box itself is empty, the description was genuinely overwritten or blanked, and you move on to getting the old text back.
Pin down what blanked it and when. Collection descriptions are a common target for two things: an SEO or content app's 'bulk optimize collections' / AI-rewrite feature that replaces your text on a schedule, and a theme publish or translation app (Translate & Adapt, Langify) that wipes the default-language content. Check Google Search Console > Performance filtered to the collection URL for the date impressions dropped, and line that up against your recent app installs, app updates, bulk runs, and theme changes. That timeline usually names the culprit — and you want it turned off before you restore, or it overwrites your fix on its next run.
Get the exact old text back, because Shopify has no undo for this field. Pull it from a copy made before the change: a Matrixify (or CSV) collections export carries the Body HTML and SEO Description columns, and re-importing just those puts every collection back at once. If you never exported, open the collection URL on the Wayback Machine (web.archive.org), find a snapshot from before the change, and copy the description straight off the page — Google's old 'cache:' view was retired, so the archive is your realistic fallback. Paste the recovered text into both the Description box and the Search engine listing meta, word-for-word rather than from memory, so you restore the version that was actually ranking.
Get it recrawled, then make sure the next blanking isn't a silent one. In Search Console run URL Inspection > Request Indexing on the restored collection URLs so Google picks the text back up (recovery takes a few days to a couple of weeks). The reason this stung is that nothing was recording your collection descriptions, so when an app or theme wiped them there was no before-state to compare or roll back to. Keep a daily snapshot of every collection's description and SEO meta — alongside your product titles, descriptions, alt-text, tags and handles — so a bulk change is flagged the day it happens, with the app that likely caused it named, and you restore the previous text in one click instead of digging through the Wayback Machine again.
