Automatically Fix 404s with AI
Detect recurring 404s, let AI choose the closest live replacement page, and create safe redirects with review controls and daily digests.
AI Auto-Redirects helps recover traffic and link equity from recurring 404s. Serpwise watches recent human 404 traffic for a domain, infers what the missing page was about, finds the closest live replacement page, and creates a redirect when the match is safe enough.
The feature is opt-in per domain from Domains -> Redirects -> Auto-redirect 404s. Scans run in the background, so a brand-new dead URL may still return 404 before Serpwise has enough signal to act.
How It Works
404 traffic -> AI match -> confidence check -> auto-apply or review queue -> redirect at the gateway- Detect recurring 404 paths from gateway request logs
- Filter bot traffic, scanner paths, known attack URLs, and legitimate 404 classes
- Infer intent from prior crawl history, URL slug tokens, and Search Console signals where available
- Find candidates among live indexed pages on the same domain
- Choose safely with a structured AI decision and confidence score
- Apply or queue based on your auto-apply settings
High-confidence redirects become active after gateway cache invalidation. Lower-confidence matches wait in the review queue.
Turn It On
Open the domain dashboard and go to Redirects -> Auto-redirect 404s.
| Setting | What it controls | Default |
|---|---|---|
| Enable auto-redirects | Turns the scanner on for this domain | Off |
| Auto-apply | Lets high-confidence suggestions go live without review | Off |
| Confidence threshold | Minimum confidence required for auto-apply | 90% |
| Default redirect type | Redirect status code for suggestions | 301 |
| Daily digest | Sends owners/admins a domain summary email | On |
| Minimum human hits | Required recurring human 404s before acting | 3 |
| Look-back window | Recent traffic window scanned for unresolved 404s | 7 days |
Use 301 for permanent replacements. Choose 302, 307, or 308 only when your redirect semantics require it.
Auto-Apply vs. Review
Auto-apply is threshold-driven:
| Match confidence | Auto-apply on | Auto-apply off |
|---|---|---|
| At or above threshold | Redirect is created automatically | Suggestion waits for review |
| Below threshold, above minimum confidence | Suggestion waits for review | Suggestion waits for review |
| Below minimum confidence | No suggestion is created | No suggestion is created |
Lowering the threshold applies more suggestions automatically. Turning auto-apply off sends every valid suggestion to review first.
What Serpwise Will Not Do
AI Auto-Redirects is conservative by design:
- It never overwrites redirects you created manually or imported by CSV
- It never redirects a dead page to the homepage as a fallback
- It prevents loops and chains before writing a redirect
- It skips bot-only 404s, AI crawler noise, exploit probes, and scanner paths
- It re-checks the chosen target before applying the redirect
- It keeps candidates inside the same locale subtree where possible
Every AI-created redirect is marked with an AI badge and can be reverted in bulk.
Bulk URL Migrations
When Serpwise sees many 404s that follow the same structural move, it can suggest one regex redirect instead of many individual exact redirects.
Example:
/blog/* -> /articles/*Bulk suggestions show the covered paths in the review queue. Approving the suggestion creates a single regex redirect rule.
Search Console Prioritization
If Search Console data is connected, Serpwise prioritizes 404s with lost search value. Suggestions and digests can show estimated recovered impressions per month so you can review the highest-impact fixes first.
Broken Target Re-Validation
When re-validation is enabled, Serpwise checks AI-created redirect targets after they go live. If a target later returns 404, becomes noindex, or otherwise stops looking valid, Serpwise disables the redirect and flags it in the next digest.
Daily Digest
The daily digest is sent per domain to organization owners and admins when there is activity. It groups:
- Applied automatically - high-confidence redirects that went live
- Needs review - queued suggestions waiting for a decision
- Re-validation warnings - AI redirects whose targets later broke
Each row includes the source path, suggested target, confidence, hit count, Search Console impact where available, and a dashboard link.
Credits
Each AI redirect evaluation uses credits. The exact cost is shown in the Auto-redirect settings panel before the feature is enabled. See Credits & AI Pricing for how credit balances and ledger entries work.
