SEO Incident Simulator
Free, no signup. Practice a defensible technical SEO investigation with deterministic evidence, plausible decisions, and clear operational consequences. Every run is a hypothetical fixture case—not a live audit or a prediction about your site.

Migration traffic collapse
A site relaunch is followed by a sharp organic-landing-page decline. Work from the affected URLs outward before changing sitewide settings.
Difficulty: intermediate
What this lab practices
- Establish a launch baseline
- Prioritize lost landing pages
- Flatten redirect chains before measuring recovery
Fixture evidence
Each source is simulated. Review the available records before choosing a next step.

The launch date and landing-page drop line up. What should the incident team do first?
Inspect the available fixture evidence before choosing an action.
Runs entirely in your browser — nothing you paste is uploaded or stored. Progress may be saved in this browser as scenario and decision IDs only; fixture bodies and visitor input are never stored. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.
How to use it
- Choose a scenario and read its learning objectives before making a decision.
- Inspect the available fixture evidence instead of guessing from the incident summary.
- Select the smallest safe next action. Consequences unlock evidence, advance the investigation, or end the path.
- At an ending, compare the evidence you found, the corrective action, and the suggested verification tool.
- Restart or rewind to test why another path is weaker. Completion is a training sequence, not a performance score.
Example scenario Fixture data
The guided Canonical conflict and index loss lab inventories five disagreeing signals for a fictional product URL. Its shortest defensible path is:
Find: HTML and HTTP canonicals disagree; navigation points to a redirecting /shop/ URL; the sitemap and redirect agree on /products/.
Fix: use /products/widget-a consistently in HTML and HTTP canonicals, sitemaps, and internal links while preserving the one-hop redirect.
Verify: retest the public signals with the Canonicalization Checker, then use Search Console for Google's selected canonical.
Every URL, date, response, and outcome in that report is invented fixture data.
What the simulation shows
An evidence artifact contains labeled facts and optional rows with a fixture observation date. A consequence explains what a choice establishes or leaves uncertain. An ending separates find, fix, and verify, records missed evidence, and names the shortest diagnostic path. It does not predict traffic recovery, crawling, indexing, or rankings.
How it works
Thirty versioned JSON scenarios define their initial step, evidence artifacts, choices, consequences, unlocked evidence, and endings. The browser-only simulator applies deterministic state transitions, records inspected evidence and decisions, and can save only scenario and decision IDs locally. No live URL, API, model, or Search Console property is queried.
Features
- Guided, intermediate, and advanced technical SEO incidents.
- Evidence spanning headers, redirects, canonical signals, crawl samples, traffic series, rendered HTML, and timelines.
- Rewindable decision paths with explicit operational consequences.
- Find → fix → verify endings linked to the relevant public tool.
Limits of the simulation
- All evidence and outcomes are authored fixtures, not measurements from your site.
- The scenario graph cannot represent every valid investigation sequence or organization constraint.
- Completing a lab does not certify production readiness or prove a fix will work elsewhere.
- Google-only states remain outside public verification and are called out as such.
Frequently asked questions
Is this a diagnosis of my website?
No. Every incident, URL, response, timeline, and outcome is fixture data bundled with the page. The simulator does not fetch your site or use your Search Console data.
Does completing a scenario prove the same fix will work on my site?
No. The labs teach a diagnostic sequence and identify what public evidence can establish. Apply the linked tools and your own evidence before making a production change.
Why does the simulator distinguish public checks from Search Console?
Status codes, headers, redirects, and page markup are observable public evidence. Google’s crawl, selected canonical, and index decisions require a verified Search Console property and are not inferred by these fixtures.

Funktionsweise
Wie lo works Thirty versioned JSON scenarios define su initial step, Nachweis artifacts, choices, consequences, unlocked Nachweis, und endings. El browser-nur simulador applies determinista Status transitions, registros inspected Nachweis und decisions, und kann guardar nur scenario und decisión IDs locally. No en vivo URL, API, model, oder Suche Console propiedad es queried.
Einschränkungen
- Simulated incidente · fixture Daten: Every fact in these labs es invented für training. Endings connect el diagnostic método a tatsächlichen herramientas, pero they hacer no claim a en vivo observation, Google-nur Status, oder business outcome.
- Status codes, cabeceras, redirecciones, und Seite markup son observables öffentliche Nachweis. Google’s Crawling, seleccionada kannónica, und índice decisions require a verificada Suche Console propiedad und son no inferred by these fixtures.
- Limits de el simulation
- All Nachweis und outcomes son authored fixtures, no measurements desde tu site. El scenario graph no kann represent cada válido investigación sequence oder organization constraint. Completing a lab hace no certify production readiness oder prove a corregir will work elsewhere. Google-nur states permanecer outside öffentliche verificación und son called out as such.
Häufig gestellte Fragen
Is esta a diagnosis de my website?
Nein. El labs teach a diagnostic sequence und identify what öffentliche Nachweis kann establish. Apply el linked herramientas und tu own Nachweis bevor de making a production cambio.
Warum hace el simulador distinguish öffentliche comprobaciones desde Suche Console?
Nein. Every incidente, URL, respuesta, timeline, und outcome es fixture Daten bundled con el Seite. El simulador hace no fetch tu site oder usa tu Suche Console Daten.
