In short. Open Top resources not found in Netlify Web Analytics, choose a reporting period, and select a resource URL to open its 404 page.
Definition: As of 17 October 2026, Netlify Web Analytics lists requested resources with the most HTTP
404 Not Founderrors in Top resources not found. Selecting a resource URL opens the error page served for that address in a new tab.
Key facts
- Netlify's Web Analytics overview documents a default reporting period of 30 days, with filters for 7 days and 24 hours.
- Netlify's chart data documentation includes all content types in the missing-resource chart, including images, text files, and other non-HTML assets.
- The IETF's HTTP Semantics standard defines
404as a response indicating that the server finds no current representation of the requested resource, or declines to disclose its existence.
Where is the chart, and what opens from it?
Netlify's overview places Web Analytics at this project report path:
Analytics & metrics > Analytics
For a project with Web Analytics enabled, Top resources not found identifies resource requests that return the most 404 errors. Selecting a listed URL opens the corresponding error page in a new browser tab.
How does the time filter change the report?
Netlify's filter instructions scope Analytics data to 30 days, 7 days, or 24 hours. The shorter filters also provide Previous to review earlier periods within the last 30 days. The selected period applies across the Analytics page.
Netlify's data collection documentation specifies hourly updates and requires a browser refresh to load updated data.
Which missing resources does the chart include?
Netlify's explanation of chart data says Web Analytics draws on Content Delivery Network server logs. The missing-resource chart covers pages alongside images, text files, and other non-HTML assets returning 404 errors.
The same documentation applies different criteria to Top pages: entries require Content-Type: text/html and a status code of 200, 201, or 304. A missing image therefore belongs within the documented scope of Top resources not found, while Top pages counts qualifying HTML responses.
The IETF's definition of 404 leaves the duration of the missing resource unspecified: the response can represent a temporary or permanent condition. The standard prefers 410 Gone when the server knows the condition is likely permanent.

FAQ
Can I use this chart to find missing files as well as pages?
Yes. Netlify's chart documentation explicitly includes images, text files, and other non-HTML assets that return 404 errors.
Does a listed 404 mean the resource is permanently gone?
The HTTP standard assigns no temporary or permanent duration to 404. It specifies 410 Gone as preferable when the server knows the condition is likely permanent.
