About this plugin
Search Signal is a free AI-SEO plugin for the AI-search era. ChatGPT, Perplexity, Google AI Overviews and Claude now answer your customers directly and cite sources, and AI bots crawl your content around the clock.
This plugin gives you three things no classic SEO plugin does – it shows you which AI bots crawl your site, it scores every page for AI answer engines (AEO/GEO), and it lets you optionally connect your own AI (Claude or ChatGPT) via MCP to manage SEO for you – on top of all the classic SEO essentials (meta, schema, sitemap, WebP). No account needed, no vendor lock-in, free forever.
See and control the AI crawlers on your site
- AI crawler log – which AI bots visited (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, Bytespider and more), when, and on which pages. Runs entirely on your own site – no external service.
- Bot classification – every bot is sorted into Training (takes content to train models), AI-Search (can cite you and send traffic) and Agent (a real person’s AI visiting now), so you know exactly who to allow or block.
- One-click AI Access Control – allow or block any AI bot by type; the plugin writes the correct robots.txt rules for you (block the training scrapers, keep the AI-search bots that cite you).
- AI referral traffic – see visitors who arrived from an AI answer (ChatGPT, Perplexity, Gemini, Copilot).
- Dead-link finder for AI – spot the 404s AI bots hit so you can fix them.
Score your content for AI answer engines (AEO / GEO)
- AI SEO Score – a site-wide scorecard across On-Page, Technical, AEO (answer-engine optimization) and GEO (generative-engine / AI-citation), measured from your own published content.
- Per-post AEO Analyzer – checks each post for a direct answer, an FAQ block, citation-readiness, a clear entity definition and freshness – the signals AI engines actually use to cite you.
- Brand Visibility – see how an AI assistant describes your brand today and what to improve (optional, uses the wptaskify service – see External services).
Optional: connect your own AI via MCP (Claude, ChatGPT & more)
Search Signal is also an MCP (Model Context Protocol) connector for WordPress. Connect your own Claude or ChatGPT once, and your AI can read your SEO data and apply fixes for you – write meta and AEO content, add schema, and optimize posts – all on your instruction.
- Bring your own AI – no lock-in. Use whichever AI you already pay for (Claude or ChatGPT). There is no bundled, per-action AI fee.
- You stay in control. The connector works on your instruction only; you approve changes, and everything above works fully without ever connecting.
- Secure by design. Connecting creates a scoped WordPress Application Password; you can disconnect any time.
This MCP connector is completely optional – every crawler, AEO and classic-SEO feature works on its own with no account and no external requests.

Why Search Signal
- Built for AI search, not just Google. Classic SEO plugins optimize for blue links; Search Signal also wins you AI citations and shows you the AI bots most SEO tools ignore.
- Free forever, no account. The crawler log, bot control, AEO score, schema, sitemap, meta and WebP are all free and work with zero setup.
- Bring your own AI. The optional MCP connector uses the Claude or ChatGPT you already have – no second AI subscription, no lock-in.
- Honest by design. The plugin is clear about what robots.txt can and can’t block, and what data (if any) leaves your site.

com). It contacts wptaskify only when YOU take an action – never automatically in the background. If you never click Connect or run a Brand check, this plugin makes no external requests.
- Connect to AI: When you click “Connect to AI”, the plugin creates a WordPress Application Password and sends your site URL, WordPress username, account email, and that Application Password to wptaskify so an AI assistant you authorize can manage your SEO. Clicking “Disconnect” sends your site URL to wptaskify to remove the connection. While connected, the plugin checks your connection/plan status by sending your site URL to wptaskify.
- Brand Visibility: When you click “Check what AI says about my brand”, the plugin sends your site URL and brand/site name to wptaskify, which asks an AI model and returns the answer. Requires an active connection.
- Why: So an AI assistant you authorize can read and write your SEO on your instruction, and so we can show how AI describes your brand.
