# Traffic drop diagnosis

Work out whether a drop is technical, a ranking loss, a demand change or a result-page change, and say which with evidence.

## Tools

- `get_search_console_changes` (website, days) - biggest click losers and gainers against the previous period, with position changes.
- `run_seo_audit` (url) - audit the pages that lost the most.
- `check_robots_txt` (url) - rule out a crawl block.
- `get_ga4_organic_traffic` (website, days) - confirm the drop in real visits, if Google Analytics is connected.

## Steps

1. Ask when the drop started if the user didn't say. Use a window that covers it: `days: 28` for a recent drop, `days: 90` for a slow decline.
2. Call `get_search_console_changes`. If Google Analytics is connected, also call `get_ga4_organic_traffic` for the same window: if Search Console clicks held but GA4 organic sessions fell, suspect tracking (a removed or broken GA4 tag), not SEO.
3. Classify the pattern from the losers:
   - **Position fell, impressions held** - ranking loss. Likely content or competition.
   - **Impressions fell, position held** - demand or seasonality. Fewer people searching.
   - **Impressions held, position held, clicks fell** - the result page changed (AI Overview, new features). CTR problem, not a ranking problem.
   - **Many pages fell at once, sitewide** - technical issue or a Google update.
4. For a sitewide drop, run `check_robots_txt` on the homepage and `run_seo_audit` on the homepage and the top 2 losing pages. Look for noindex, canonical, robots or server errors first.
5. For page-level drops, run `run_seo_audit` on the top 3 losing pages.
6. Only call something a Google update if the timing matches and nothing technical explains it. Say it's a hypothesis.
