SEO Toolkit

SEO Toolkit groups keyword checker, page speed analyzer, internal link checker, link extractor, and site audit tools for on-page SEO workflows — browser smoke-checks plus agent playbooks.

About the SEO Toolkit toolkit

Use the SEO Toolkit when you need on-page checks (meta, headings, keywords), technical crawl hygiene (HTML page-speed proxies, robots, sitemap, redirects), GEO readiness (llms.txt, AI Overview readiness), or a focused site audit — without jumping across unrelated converters. Open any tool in the browser with no signup. Speed scores are HTML-based proxies, not Chrome field CrUX or Lighthouse lab. API-backed SEO tools in this kit also run via REST and MCP on one API key and 500 free credits per month. **Start here paths:** (1) **Technical launch** — Page Speed Analyzer → Robots.txt Checker → Sitemap XML Validator → Indexability Checker. (2) **On-page** — Meta Tags Analyzer → Heading Structure → Schema Markup Validator. (3) **GEO / agents** — llms.txt Validator → GEO SEO Auditor → AI Overview Readiness. (4) **Crawl architecture** — Internal Linking (orphan mode) → Broken Link Checker. (5) **Agents** — <a href="/developers/seo-agent">SEO audit MCP</a> playbooks on the same key.

Frequently asked questions

What jobs does the SEO Toolkit cover?

Four clusters: on-page (meta, headings, keywords, schema), technical crawl (speed proxies, robots, sitemap, redirects, indexability, soft 404), GEO / AI-search readiness (llms.txt, AI Overview readiness), and audits (SEO audit, bulk auditor, competitor compare). Mixed Content Checker lives here and is cross-linked from Security Toolkit.

Are page speed / Core Web Vitals scores from Lighthouse or CrUX?

No. ToolYour page-speed and CWV job scores are HTML-based proxies (and related heuristics), not Chrome UX Report field data or Lighthouse lab traces. Use them for actionable fix lists, then confirm with field/lab tools when you need production SLOs.

Do I need an account to use SEO Toolkit tools?

No for browser use. Create a developer account only if you want REST or MCP access to API-backed SEO tools.

Can agents run SEO Toolkit tools via MCP?

Yes for API-backed tools in the kit. Connect at https://api.toolyour.com/mcp with the same API key and monthly credit quota as REST. See SEO agent.
