Technical SEO and Diagnostic Guides

Available diagnostic guides

The current Wave 1 collection covers the highest-priority access, routing, discovery, structured-data, AI crawler, and content-quality findings:

• Why Your Website Is Not Indexed — diagnose discovery, response, noindex, canonical, rendering, and content causes.
• Robots.txt: What It Controls and What It Does Not — validate user-agent groups, path rules, rendering assets, and sitemap references.
• Canonical URLs: Preventing Duplicate and Conflicting Pages — align the preferred URL with redirects, links, sitemaps, and CMS routes.
• Internal Linking: Helping Users and Search Engines Find Context — repair orphan candidates, generic anchors, and weak hub-to-guide relationships.
• Structured Data Errors: How to Validate and Fix Schema — separate syntax, supported-feature, and visible-content problems.
• AI Crawler Access: OAI-SearchBot, PerplexityBot, and Robots.txt — set purpose-specific crawler policies and verify infrastructure behavior.
• Content Citability: Making Pages Easier to Understand and Reference — improve direct answers, evidence, authorship, sources, and context.

How to use a diagnostic guide

1. Match the scanner rule or observed symptom to the focused guide.
2. Confirm the condition on the exact canonical URL and rendered public response.
3. Identify whether the cause belongs to the page, route, CMS, template, extension, CDN, firewall, or server.
4. Make the narrowest correction that resolves the evidence without changing unrelated global behavior.
5. Verify the final output and rescan the representative URL.
