Matomo Extension

seo-matomo

Self-hosted analytics surface. Use Matomo as a privacy-first GA4 alternative when you own your analytics data, want zero Google dependency, or operate behind a strict data-residency boundary. The same seo-matomo skill works against Matomo Cloud and self-hosted instances.

Prerequisites

• Run extensions/matomo/install.sh or install.ps1.
• A Matomo instance URL (https://analytics.example.com).
• A Matomo API token_auth with view access on the sites you analyze.
• (Optional) A default idSite to avoid passing --site-id on every call.

Routing

Command	Underlying script
/seo matomo check	"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_auth.py --check
/seo matomo organic [site-id]	"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_report.py organic --site-id <id>
/seo matomo top-pages	"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_report.py top-pages
/seo matomo device	"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_report.py device
/seo matomo country	"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_report.py country
/seo matomo referrers	"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_report.py referrers
/seo matomo keywords	"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_report.py keywords

All commands accept --days (default 28), --limit, --site-id, and --json. The site ID falls back to MATOMO_SITE_ID from settings.

When this skill applies

• The user wants Google-free analytics or has a Matomo instance already configured. Common in EU privacy-first setups, regulated industries, and teams who own their analytics.
• The user explicitly says "Matomo", "self-hosted analytics", or asks to replace GA4. For Google Search performance use seo-google; this skill is the reporting substitute.
• The user is migrating from GA4 and wants the same report types (organic trend, landing pages, device / country split, referrer split) sourced from Matomo's Reporting API.

Cross-skill delegation

• For Google Search Console / CrUX / Indexing, route to seo-google. seo-matomo covers reporting (visits / pages / referrers), not search performance metrics.
• For AI Overview / GEO citability work, route to seo-geo. Matomo offers no LLM-specific signals.
• During /seo audit, the orchestrator spawns the seo-matomo agent (analogous to seo-google) whenever "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_auth.py --check succeeds. Both agents can be active simultaneously when the user has both GA4 and Matomo configured.

Self-hosted instance on a private address

Every Matomo request goes through claude-seo's SSRF guard: the instance URL is validated and DNS-pinned, and a redirect off the instance is refused. Private, loopback, and link-local addresses are refused by default. When the user's instance lives on one (http://matomo.internal:8080, http://192.168.1.20, http://localhost:8080), tell them to name it in the CLAUDE_SEO_LOCAL_TARGETS allowlist:

export CLAUDE_SEO_LOCAL_TARGETS="matomo.internal:8080"

Entries are host or host:port, comma-separated, matched exactly. The allowlist covers only the top-level instance URL; redirect targets and every other host stay fail-closed, and cloud metadata addresses are refused even when listed. Never suggest disabling the guard or editing url_safety.py: the allowlist is the supported route. Details in extensions/matomo/docs/MATOMO-SETUP.md and SECURITY.md.

Error Handling

• Refused by the SSRF guard (error names CLAUDE_SEO_LOCAL_TARGETS): the instance is on a private address that has not been allowlisted. Give the user the exact export line from the error, which already carries the right host:port.
• Refused redirect: the instance answered a 30x pointing at another host. MATOMO_URL is pointing at a redirector rather than at the Reporting API. Ask the user for the URL their instance actually serves the API from.
• Missing credentials: report which env vars / config keys are unset and remind the user to run extensions/matomo/install.sh or "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_auth.py --setup.
• HTTP 401/403 from Matomo: the token lacks view access for the given site. Verify the token scope in Matomo Administration -> Personal -> Security -> API Tokens. The skill never logs the token.
• result=error payloads from Matomo (e.g. invalid idSite): surface the message verbatim; do not guess.
• Connection / SSL / timeout: report the network failure class (ConnectionError, SSLError, timeout) and confirm MATOMO_URL resolves.

Output Formatting

• Tables for time-series, device, and country data.
• Critical / High / Medium / Low priority for any cross-skill actions surfaced from Matomo data.
• Always label the data source as "Matomo Reporting API (live)" to distinguish from GA4, CrUX, or static crawl analysis.
• For organic keywords, surface the anonymized_share_pct prominently. Many keywords will be "(not provided)" due to browser privacy and Matomo's anonymization rules; this is normal, not a data bug.
