# Technical SEO Checker - Compact Output Templates

Use one reporting shape: evidence -> checks -> issues -> fixes -> score. Mark unsupported checks `N/A`; cite crawl date, source, sample size, and representative URLs.

## Shared Conventions

| Item | Rule |
|------|------|
| Status | `✅` pass, `⚠️` partial risk, `❌` fail |
| Severity | `P0` blocks indexing/revenue, `P1` suppresses performance, `P2` hygiene |
| Score | `/10` per section; final report rolls to `/100` |

## Step Map

| Step | Focus | Must Capture |
|------|-------|--------------|
| 1 | Crawlability | robots.txt, sitemap, crawl sample, crawl waste |
| 2 | Indexability | coverage, noindex, canonicals, 4xx/5xx |
| 3 | Performance | LCP, INP, CLS, TTFB, blocking resources |
| 4 | Mobile | viewport, content parity, tap targets, overflow |
| 5 | Security | SSL, HTTPS, mixed content, HSTS, headers |
| 6 | URL structure | host/protocol, slugs, parameters, redirects |
| 7 | Structured data | current schema, errors, missing opportunities |
| 8 | International | hreflang, return tags, x-default |
| 9 | Summary | scorecard, priority queue, roadmap, monitoring |
