One CLI command that tells you exactly why ChatGPT, Gemini, Claude, and Perplexity aren't recommending your store — and how to fix it.

| Component | Version |
|---|---|
| Magento Open Source | 2.4.6, 2.4.7, 2.4.8 |
| Adobe Commerce | 2.4.6, 2.4.7, 2.4.8 |
| Adobe Commerce Cloud | All current versions |

| Themes | Luma, Hyvä |
Tested with: Magento Open Source 2.4.7-p3 + PHP 8.3 + Hyvä 1.3.
The evidence layer. Signals 1–15 audit configuration; v4 adds two signals
that audit reality: waf_reality (does the edge actually let the bots in that
robots.txt invites?) and ai_crawler_activity (which AI crawlers demonstrably
visited, from GDPR-safe evidence sources). Plus: purpose-classified bot
grading (blocking GPTBot is a licensing choice, blocking OAI-SearchBot is an
AEO failure), GitHub Actions CI with a Mage-OS installability job, i18n
dictionary, configurable cron schedule, vendor-neutral & switchable fix
hints, and a security fix in the CrUX checker (TLS verification re-enabled,
API key moved from URL to header, encrypted key now actually decrypted).
Full details in CHANGELOG.md.
Major release — see CHANGELOG.md for the breaking-change migration guide if you have custom checkers.
20 signals (up from 9), reflecting the actual AEO landscape of 2026: AI shopping integrations, merchant policies, agentic commerce, and structured-data quality.
6 new checkers:
merchant_policies—MerchantReturnPolicy+OfferShippingDetails— required by Google AI Mode and ChatGPT Shopping since Jan 2026organization_schema— brand entity in AI knowledge graphsucp_profile— Universal Commerce Protocol (/.well-known/ucp), with built-in security check that detects leaked JWK private keysjsonld_quality— three-page schema breadth audit (homepage / category / product),WebSite+SearchAction,BreadcrumbList,ItemListwell_known— discovery matrix for/.well-known/{ucp,ai-plugin.json,security.txt,mcp}core_web_vitals— LCP / INP / CLS via Google CrUX API (free, opt-in with API key)
Refactored architecture (this is the BC-break):
- Shared
Service\HttpCache— eliminates duplicate fetches across checkers (hundreds of redundant HTTP requests on multi-store audits before, dozens now) Service\StoreUrlSampler— single source of truth for product / category / CMS URL sampling- New
--categoryand--fail-on-severityCLI flags for CI workflows - Per-checker exception isolation — slow or failing checkers no longer halt the audit run
Note on access-log monitoring: an
ai_bot_trafficchecker was prototyped during v3 development and excluded from the release after security review — it encouraged broad read access on/var/log/nginx/, didn't work on Cloud/containerised hosting, and was dominated by false positives behind edge caches. AI-bot traffic is better measured at the edge (Fastly/Cloudflare Analytics) or via APM (New Relic, Datadog) than inside a PHP module. See CHANGELOG.md "Considered and rejected" for the full rationale. Thelive_signalcategory remains inCheckerInterfacefor third-party modules with secure live-signal sources — notablyangeo/module-aeo-brand-visibility.
Two layers since v4.0.0: configuration signals verify the store is set up for AI engines; the evidence layer verifies AI engines actually reach it.
| # | Signal | Code | Weight | Category | What it validates |
|---|---|---|---|---|---|
| 1 | robots.txt — AI bots | robots_txt |
1.0 | technical | 12 AI bots, syntax errors, versioned UAs, conflicting rules |
| 2 | llms.txt — content map | llms_txt |

| 3 | llms.jsonl — catalog | llms_jsonl |

★ = added in v3.0.0 · ★★ = added in v4.0.0 · ★★★ = added in v4.1.0.
Almost no Magento store has opted into A2A, and scoring them all down for a
protocol they never adopted would make the number less useful, not more. So
agent_card asks the UCP profile first. If the store advertises an a2a
transport, the card is part of the contract and its absence is a FAIL. If
it does not, the signal passes with applicable: false in the details.
One case is flagged regardless: a card served only at /.well-known/agent.json,
the path A2A used before 0.3. A spec-compliant 1.0.0 client never looks there,
so the operator believes they have published a card that, to the protocol, does
not exist.
The bot catalog (BotRegistry) classifies every
AI agent as training (collects pages to train models), search
(indexes for answer engines — this traffic earns citations), or fetcher
(real-time page access for a user asking right now):
- Blocking a search crawler (OAI-SearchBot, PerplexityBot, Claude-SearchBot) fails the audit — the store disappears from AI answers.
- Blocking a training crawler (GPTBot, ClaudeBot, CCBot, Bytespider) is a respected licensing choice — reported, never punished. Opting out of model training does not remove a store from AI search.
- Opt-out tokens (Google-Extended, Applebot-Extended) never crawl anything themselves and are reported as conscious-choice notices.
waf_reality and ai_crawler_activity corroborate each other:
| waf_reality | ai_crawler_activity | Diagnosis |
|---|---|---|
| edge blocks probe | zero hits | Real block — allow-list AI crawlers in your WAF/CDN bot management |
| edge blocks probe | healthy hits | Verified-bot program correctly rejecting UA spoofers — no action needed |
| consistent | zero hits | Store likely not yet discovered — work on feeds, llms.txt, citations |
| consistent | search hits | Fully AI-visible ✔ |
Evidence sources for ai_crawler_activity (pluggable via
Angeo\AeoAudit\Api\BotHitSourceInterface):
-
Built-in instrumentation (default, zero-config): a frontend plugin counts AI bot requests at the PHP layer on every hosting model. Limitation reported honestly: requests served entirely from full-page cache never reach PHP and are not counted.
-
Webserver access log (opt-in): set an absolute path under Stores → Configuration → Angeo AEO → Live Signal. Only the trailing 8 MB is read; combined and JSON-lines formats are auto-detected. Never
chmodthe live log — grant targeted read access instead:# point-grant read to the PHP user (survives permission audits): setfacl -m u:www-data:r /var/log/nginx/access.log # …or copy bot-filtered lines on rotation (logrotate postrotate): grep -Ei 'GPTBot|OAI-SearchBot|ClaudeBot|Claude-SearchBot|PerplexityBot|Amazonbot|Applebot|meta-externalagent|CCBot|Bytespider' \ /var/log/nginx/access.log.1 > /var/log/ai-bots/access.log
Behind a CDN the origin log under-counts (cache hits never reach the origin) — the report says so explicitly.
-
Your own adapter (CDN analytics APIs are the highest-fidelity source — they see cache hits too). Implement
BotHitSourceInterface, register via di.xml on the checker'ssourcesargument.
Privacy: only aggregates — bot code, class, store, date, count — are ever
persisted (angeo_aeo_bot_hit). No IPs, no URLs, no raw user agents, no log
lines. Retention (default 90 days) is enforced by cron. Absence of any
source is an informational note, never a score penalty.

Some checkers need configuration. All are accessed via: Stores → Configuration → Angeo AEO.
| Setting | Purpose |
|---|---|
| CrUX API Key | Required by core_web_vitals checker. Free key from console.cloud.google.com — enable the Chrome UX Report API. Stored encrypted. |
- Marketing → Angeo AEO → AEO Audit Results — full history grid
- Marketing → Angeo AEO → Score Trend — line chart of AEO score over time
- ▶ Run Audit Now button (on the Audit Results grid, Score Trend, and result
view pages) — triggers an on-demand audit. Since 3.1.0 this is a POST action
protected by the admin form key and the dedicated
Angeo_AeoAudit::run_auditACL permission; the old GET menu entry was removed.
| Score | Label | Typical situation |
|---|---|---|
| 0–25% | Critical | Default Magento install. AI crawlers blocked. No schema. |
| 26–50% | Needs Improvement | Some fixes applied. Feed or merchant policies missing. |
| 51–75% | Needs Improvement | Core signals in place. UCP, ai-plugin.json, or hreflang missing. |
| 76–90% | Good | Strong foundation. Minor gaps in well-known or CWV. |
| 91–100% | Excellent | Full 2026 AEO compliance. |
Scheduled audit — default every Monday at 03:00 server time, configurable under Stores → Configuration → Angeo AEO → Scheduled Audit since v4.0.0. Results saved to DB (last 50 per store); expired bot-hit counters pruned per the retention setting.
bin/magento cron:run --group=defaultFor fast daily checks (without external APIs or log scans), schedule an
additional cron job calling the audit with --category=technical.

Angeo\AeoAudit\Model\Checker\AbstractChecker, which provides HTTP cache,
URL sampling and JSON-LD parsing), and register via di.xml:
