How to Track 404 Errors for Affiliate Marketing
You spent hours writing the perfect product review. You included your affiliate links, promoted it to your email list, and waited for the commissions to roll in. Instead, readers are hitting 404 errors on half your links. You are not earning a cent, and your readers think you are useless.
Why 404 Errors Matters for Affiliate Marketing
Dead links kill commissions instantly. Unlike regular content where a broken link is a minor annoyance, affiliate links are your income. Every 404 means zero commission, guaranteed.
SEO value evaporates. When you link to external sites and those links break, Google notices. It treats your site as low quality. Your rankings drop, and so does your organic traffic.
Readers stop trusting you. If someone clicks three affiliate links and all return errors, they will stop clicking. They will also stop reading. Your audience erodes.
Merchant changes happen silently. Companies update their product pages constantly. A product you linked to last month might be gone today. You only know if you are monitoring.
How to Check in GA4
Set up event tracking for all your affiliate link clicks. In GA4, create a custom event for outbound clicks. Track the destination URL as a parameter.
Create a report showing click-through rates by affiliate. Compare high-click links against your conversion data. If a link has high clicks but zero conversions, investigate whether it returns a 404.
Use Google Search Console to find 404 errors on your site. It shows which URLs Google tried to crawl and could not find. Check this weekly.
