Page audits
Audit a page
Single page or a bounded site crawl of up to 5 pages.
No audits yet. Your first run is free.
Issue centre
Prioritised issues
Every issue shows the element found, why it matters and the suggested fix. Mark an item reviewed to track your own progress; this status is stored locally and does not alter the website.
Run an audit to see issues here, ranked by impact.
AI readiness
Ready for AI-assisted discovery?
After an audit, see scores for the measured categories below. These are diagnostic signals, not predictions of search ranking or AI citations.
Run an audit to show category scores here.
SEO
Technical foundations, content structure and crawlability.
AEO
Clear answers mapped to real customer questions.
GEO
Evidence and content clarity for AI-assisted discovery.
What we check
AI crawler access
Are GPTBot, PerplexityBot, ClaudeBot and Google-Extended allowed or blocked in robots.txt?
llms.txt & sitemaps
Is there a clear machine-readable guide to your key pages?
Structured data
Organization, FAQ, Product, LocalBusiness and Article schema, validated.
Answer-ready content
Question-style headings, short direct answers and visible evidence.
Entity clarity
Is it obvious who you are, what you offer and where you operate?
Speed & Core Web Vitals
LCP, CLS and INP, since slow pages lose both clicks and citations.
This preview generates recommendations. Automated publishing and live AI-provider execution are not enabled here.
Competitors
Find your competitive landscape
Discover potential competitors from public search results, review the source evidence, then add relevant businesses to your local watchlist.
Automated discovery
Analyse your market and find competitors
Signal analyses your homepage title, description and key headings, then searches for service providers in your chosen market. Review source evidence before adding a suggestion; candidates are not verified market-share rankings.
Enter your website to begin. Add a short market description for more relevant results.
Manual option
Add a competitor yourself
Already know a competitor? Add its public website directly.
Saved competitors
The watchlist supports up to three competitors on this browser.
No competitors saved yet.
Reports
Reports & exports
Download a report as JSON, export your workspace as JSON or CSV, and remove local report copies. PDFs and shareable hosted links are not yet enabled.
Reports are saved in this browser only. Clearing site data or switching browsers may remove or hide them; this does not clear server-side quota or payment records.
No reports yet.
Integrations
Connect Signal to your workflows
Use a private REST API or an MCP-compatible client to request audits and create paid checkout sessions. A server-side API key is required; it is never placed in this page or browser storage.
MCP server
Connect an MCP client using Streamable HTTP. Available tools: service status, pricing, public-page audit, and one-time checkout creation.
Checking configuration…
Add the key as a secret in your MCP client. Do not paste it into this dashboard, a public workflow, or a shared document.
n8n and webhooks
Use an n8n HTTP Request node with the private REST endpoint. Paid audits return a Stripe Checkout URL; after payment, call the audit action again with the returned session ID.
REST workflow supported
Signal does not yet push events to arbitrary webhook URLs; this is an authenticated pull/request API.
Google Search Console
OAuth and Search Console data are not connected yet. No property permissions are requested or stored by this preview.
Not connected
Chrome developer preview
The Vercel preview includes a local-only Chrome extension ZIP for testing. It is not published, store-reviewed, or connected to managed cloud reporting; install only if you understand the developer-preview permissions.
Developer preview
Service security
API calls use bearer authentication, shared IP rate limits, public HTTP(S) URL validation and server-side payment verification. The API key stays in Netlify environment variables.
Checking API, MCP and checkout configuration…
Activation checklist
Set SIGNAL_API_KEY to a strong random secret in Netlify environment variables to enable REST and MCP. Set STRIPE_SECRET_KEY to a restricted Stripe secret key to enable checkout. Then redeploy and check the status above. Secret values are never returned by the status endpoint.
MCP and API endpoints are implemented, but remain disabled until the server-side key is configured. Paid checkout remains disabled until Stripe is configured.
