Shopify 404 monitor
A Shopify 404 monitor records missing URLs that shoppers already requested, then shows which ones are worth a redirect.
A 404 monitor watches the page Shopify already serves when a URL is missing. It is not a crawler that invents a list of theoretical broken links. 404Guard is that monitor for Shopify stores: the app embed checks the page type, and a 404 visit becomes a path, a count, and a source.
What you see
Overview shows 404 visits, how many distinct broken URLs those visits belong to, how many issues you have fixed, and how many redirects you created. The table under Broken URLs needing attention sorts by impact. Open a row for the chart, the sources, and the internal pages that linked to the missing URL.
That is the working list. Twenty-three people trying /products/winter-jaket is a job. Four hundred paths that nobody requested are not.
What it does not do
- It does not crawl the catalog on a schedule.
- It does not score the store's SEO, rewrite titles, or audit images.
- It does not identify the shopper. The path and the referrer are enough.
- It does not change what the 404 template looks like.
How it is turned on
Install the app, then enable the embed in the theme editor. Shopify leaves embeds off until you save them. Enable monitoring is the short version. When the badge says Monitoring active, the next real 404 is eligible to show up. You can request a missing path yourself to confirm the pipeline.
Search Console still matters for what Google has indexed. The monitor answers a different question: which missing URLs did people open. Pricing is free. The privacy details are on the privacy page.
