If you’ve ever checked your Google Analytics or Google Search Console data and noticed visits to a page that actually returns a 404 Not Found error, you’re not alone. This scenario can be confusing and frustrating: how can visitors be landing on a page that doesn’t exist? Understanding why 404 traffic analytics appears in your reports is crucial for website health and user experience, and it also helps you fix top 404s that might be hurting your SEO and referral traffic.
What Is a 404 Error?
A 404 Not Found error means the server couldn’t find the page a user requested. It’s one of the most common HTTP status codes you’ll encounter on the web, signaling a broken or missing URL.

Important points about 404 errors:
- The page URL is invalid or deleted. The link leading to that URL could be misspelled or outdated. Properly managed, 404 helps search engines understand the site’s structure. Too many or unmanaged 404s can harm user experience and SEO.
Because 404 pages show a user-friendly error message rather than real content, many site owners wonder why their analytics still record visits to these missing URLs.
Common Reasons for Referral Traffic to 404 Pages
There are multiple reasons why your Google Analytics or redirect manager vs htaccess Google Search Console reports show traffic to URLs that return 404 errors:
1. Outdated or Changed URLs (Common With Sponsored Content)
Marketing and sponsored posts sometimes disappear from publisher sites after a campaign ends due to copyright, contractual obligations, or cleanups. When those URLs vanish without redirects, visitors clicking old ads, referrals, or saved links get bounced to a 404.
These missing sponsored URLs often create unexpected referral traffic to 404 pages, making it look like your site is losing valuable visitors.
2. External Sites Linking to Broken URLs
Other websites may link to a page that used to exist but was deleted or moved without a redirect. These referral links still send users to your 404’s.
3. Typos or URL Structure Changes
CMS migrations or URL slug changes can cause links to break if proper redirects aren’t set up. For example, a missing trailing hyphen or character in the URL slug results in a 404.
4. Bots and Crawlers
Not all traffic is human. Search engine crawlers and bots also visit 404 pages as they try to index your site or scan for vulnerabilities, and these hits can register in analytics.

5. Incorrect Implementation of Analytics Code
In rare cases, misconfiguration of analytics or Google Tag Manager can report synthetic pageviews for 404s or redirect tracking errors.
How To Troubleshoot Referral Traffic to 404 Pages: Fast Reader Steps
If you see suspicious or unexpected referral traffic landing on 404 pages, follow these quick debugging steps to identify and fix the issue:
Inspect the URLs in Analytics Reports: Check the exact URLs generating 404 traffic in Google Analytics under Behavior > Site Content > All Pages, filtering for pages with 404 titles or paths. In Google Search Console, look at Coverage reports for “Not Found” errors. Verify URL Validity: Copy a sample 404 URL and test it in an incognito browser tab to confirm the 404 error genuinely appears. Make sure to check for trailing hyphens or missing characters in the slug. Check Referrer Sources: Identify which external sites or campaigns are sending visitors to the 404 URLs by looking at Referral reports in Google Analytics or Acquisition > All Traffic > Source/Medium. If it’s an old sponsored campaign, confirm if the content has been removed. Search the URL or Page Title: Try searching the title or keyword phrases of the missing page on your own site’s search or Google site: search (e.g., site:yoursite.com “page title”). Sometimes copy of the page exists under a new URL. Look for Redirect Chains: Use tools like Screaming Frog, Ahrefs, or online redirect checkers to test if old URLs redirect properly. Aim to avoid redirects chains longer than 2 hops. Check CMS and Hosting Logs: If you have backend access, audit server logs or CMS error logs for 404 hit trends and the origin of those requests. Set Up Proper Redirects: If the missing page was moved or replaced, implement 301 redirects from the 404 URL to the new location or relevant category pages. Avoid redirecting everything to homepage — that’s a poor user experience.How to Find a Missing Article on a Publisher Website
When you encounter a 404 page and want to locate the original content, here are some practical techniques:
- Use the Wayback Machine (archive.org): Enter the missing URL to see archived snapshots of the page if it existed historically. Search via Google Cache: Perform a Google search for the missing page title or keywords with cache: filter to see cached versions. Check Internal Site Search: Use the publisher’s site search tool for similar articles or copied content. Browse Relevant Categories or Tags: Navigate the site’s related sections — sometimes content moves to a new category or url slug. Contact Site Support: Reach out to website editors or help desks if you suspect the article was removed or relocated.
