Frequently Asked Questions

Common questions about no404 – Auto 404 Redirect

Yes. The matching engine is a hosted service, so the plugin needs an API key. There is a free plan that covers 1,000 lookups per month, and local caching means a lookup is not the same as a page view.

Nothing breaks. The plugin fails open: if a request times out or errors, no redirect happens and your theme's 404 page is shown as usual. The wait is capped by the timeout you configure, 1.5 seconds by default, and only ever applies to 404 pages. After a failure the plugin pauses outgoing requests for a while so a service outage does not add that delay to every 404 on your site.

No. Results are cached for an hour by default, so the same URL costs at most one lookup per hour. Results with no match are cached too. Static files and admin paths are never sent. The exceptions are visits from an ad click or from an AI assistant such as ChatGPT: they are always looked up, so that traffic shows up in full in your dashboard.

No. The query string never leaves your site. When a visit carries an ad click ID (gclid, msclkid) or a paid utm_medium, the plugin sends only the ad network — google, microsoft, meta or other. In the same way, when a visitor arrives from an AI assistant (a utm_source such as chatgpt.com, or a referrer such as claude.ai), only the assistant's name is sent — chatgpt, claude, perplexity, gemini, copilot, meta or other.

Only a truncated one. Since 1.0.3 the plugin sends the network part of the visitor's IP (203.0.113.0 rather than 203.0.113.45), a pseudonymous visitor ID (a hash of the address keyed with a secret only your site knows) and the browser's user agent, so the dashboard can separate bots from people and count unique visitors. The full address never leaves your site. Before 1.0.3 every 404 was recorded under your own server's address. You can change or remove this data with the no404_visitor filter.

Add a manual redirect for that URL in your no404 dashboard. Manual redirects always take priority over automatic matches. Note that if the redirect was sent as a 301, browsers may have cached it, which is why speculative matches are sent as 302 by default.

No. The plugin hooks into template_redirect at a very low priority, so those plugins resolve their own redirect tables first. no404 only acts on 404s that nothing else handled.

Yes. Each site keeps its own API key, its own settings and its own cache.

Redirected responses carry an X-Redirect-By: no404 header. Every request is also listed in the 404 Events tab of your no404 dashboard.

Yes. Settings → no404 has an "Excluded paths" field. Enter one path prefix per line. Static files and admin paths are excluded automatically.
