A customer clicks a Google link to a product page on your ecommerce store. They land on a “Page Not Found” error. They close the tab and buy from a competitor instead.
This happens thousands of times across ecommerce sites every day. Most store owners never know.
Why 404 Errors Matter for Ecommerce
Direct revenue loss. Every broken link is a blocked purchase. If a popular product page returns 404, you lose every customer clicking that link.
SEO damage. Google lowers rankings for sites with many broken pages. Your search visibility drops when 404s accumulate.
Brand erosion. Customers notice broken experiences. Repeated 404s train shoppers that your site is unreliable.
Inventory confusion. Deleted products create 404s. But so do seasonal items and misnamed URLs. You need to know the difference.
How to Check in GA4
GA4 shows 404 data through its Pages and Screens report. Navigate to Reports > Engagement > Pages and screens. Filter by page path containing “404” or “not-found.”
Look for pages with high views but short engagement time. These are customers bouncing from broken links.
Use the Explore tool to create a detailed report. Add “Page path and screen class” as a dimension. Filter for 404 status. Add “Sessions” as a metric.
Export this data weekly. Prioritize fixing high-traffic 404s first. Set up alerts for sudden spikes.
The Easier Way
Finding and fixing 404s in GA4 takes technical setup. ClawAnalytics makes this simple.
ClawAnalytics shows a dashboard of every 404 error on your ecommerce site. Example questions answered:
- Which broken pages get the most traffic?
- How many sales did I lose to 404s this week?
- Are deleted products causing the most errors?
You see exactly which URLs need fixing. One ecommerce owner fixed three high-traffic 404s and recovered $4,000 in lost sales per month. Another used 404 data to find deleted product pages still linked from email campaigns.
Quick Wins
Create a custom 404 page. Include a search bar, popular products, and a contact option. Turn dead ends into conversion opportunities.
Set up redirects for deleted products. Redirect old product URLs to similar items. Never leave customers at a dead end.
Audit external links monthly. Partner sites change URLs. Reach out to update connections.
Monitor 404s in real time. Use alerts for sudden spikes. Fix problems within 24 hours.
