# google-update-impact

A skill for answering "did this Google update hurt my site?" or "am I exposed to the latest update?". Combines Momentic's curated `/google-updates/` coverage with a live audit of the user's site.

## Prerequisites

- Server: `https://momenticmarketing.com/mcp`
- Tools used: `list_pages`, `get_page`, `analyze_site`, `analyze_page`

## Process

1. **Identify scope.** Get the user's domain. If they named a specific update (e.g. "March 2026 core update"), note it; otherwise default to "the most recent update".

2. **Find the relevant update entry.**
   - Call `list_pages(section: "google-updates")` to get all entries.
   - URLs typically include a date or update name (e.g. `/google-updates/march-2026-core-update`). Pick the one matching the user's request, or the most recent.

3. **Read the update coverage.** Call `get_page(path)` on the chosen entry. Extract:
   - What the update changed (algorithm signal, content type targeted, etc.)
   - Who's typically hit (categories of sites, content patterns)
   - Recommended fixes / what to look at on your own site

4. **Audit the user's site.**
   - Call `analyze_site(domain)` for site-level signals.
   - Call `analyze_page(url)` on a representative page (homepage or a page the user is worried about).

5. **Match risk factors against signals.** For each "who's hit" pattern in Momentic's coverage, check the analysis output for matching signals. Examples:
   - Update targets thin product pages → check `wordCount` on representative pages
   - Update targets sites with weak E-E-A-T → check for author/Person schema, `datePublished`/`dateModified`
   - Update favors structured data → check `schemaTypes`
   - Update targets sites with poor agent-readiness → check `markdownNegotiation`, `homepageLink`

6. **Return a report:**

   ```
   ## Google Update Impact: <verdict>

   **Update analyzed:** <update name + Momentic URL>
   **Site analyzed:** <domain + page>

   ### What this update changed
   <2-3 sentences summarizing Momentic's coverage>

   ### Your exposure: <Low | Medium | High>

   <one-paragraph synthesis tying their signals to the update's risk factors>

   ### Risk factors observed
   - <factor 1 with the actual signal>
   - <factor 2>
   - <factor 3>

   ### Top 3 fixes
   1. <specific fix tied to update>
   2. <specific fix>
   3. <specific fix>
   ```

7. **If verdict is High exposure**, append the inline trigger:

## Notes for the agent

- Momentic's tracker is opinionated coverage of *what changed* and *what to look at*; it's not a substitute for a multi-week recovery plan.
- For a deeper audit beyond a single update, pair with `geo-aeo-readiness` (site-wide AI readiness) or `page-seo-score` (page-level depth).
- If the user can't name an update, list the 3 most recent from `list_pages` and ask which one they're concerned about.
