What no404 does
Detect. Understand. Recover.
Find the 404s that matter
Not every 404 matters. See which missing addresses real visitors are actually reaching; bots are shown separately.
See where they came from
Ads, search engines, social media, other websites or a broken link on your own site: every 404 shows its source.
Send them somewhere useful
no404 sends the visitor to the closest matching live page. You decide how strong a match must be; below that, the 404 stays.
Don't let your ad spend
burn on a 404.
If you run Google or Meta ads, every click costs money. When that click lands on a deleted product or an old link, you pay for it and the visitor still sees an error page and leaves. no404 catches that click and sends the person to the closest live page instead.
Ad → deleted page → 404
You paid for the click and the visitor left. Budget wasted.
Ad → 404 → the right page
The visitor was sent to the closest live product instead of an error page.
Why no404
Don't leave your 404s to chance
You see your 404s before anyone else
Every 404 shows up in the dashboard with who triggered it, from where, and from which page.
Paid clicks shouldn't land on nothing
no404 counts ad clicks that end in a 404 separately, and prices them once you enter your cost per click.
Stop maintaining a redirect list
It reads your catalog from your sitemap, so there is no rule list to maintain.
Setup in 3 steps
Working within minutes
Connect Search Console
Sign in with Google and pick one of your verified sites. Google proves ownership, so there's no form to fill in.
Pick your sitemap
Choose one of the sitemaps you submitted to Search Console; no404 learns your live pages and builds the matching catalog.
Finish setup
Install the WordPress plugin, the PrestaShop module, or the Laravel or Node.js package, or connect through the server API or the snippet. Every 404 then shows up in your dashboard.
Integrations
Works with your stack.
Ready-made integrations where they exist; everywhere else, the server API or a small snippet on your 404 page.

Server-side redirects
The WordPress plugin, the PrestaShop module, the Laravel and Node.js packages and the server API return a real 301 or 302, so what the old page earned in Google moves to the new one.
Your call
Confidence you control
Set per site how strong a match must be for a 301. Below that, the visitor gets a 302 or the 404 stays; traffic unrelated to your catalog is never sent to your home page.
1.5 s
Your site never waits
If no404 doesn't answer within 1.5 seconds (the default), the plugin or module shows your own 404 page. A slow API never slows your site down.
0
Raw visitor IPs stored
IP addresses are stored masked, with an irreversible hash for unique counts; the plugin and module never send a visitor's full IP.
