    Understanding VibeSignal: what the AI Signal Score measures

    How VibeLeak scores whether AI crawlers, answer engines, and autonomous agents can find, read, and use your site — and how to read the five category rows in the scan spotlight.

    Product signal

    Trust is for humans. VibeSignal is for machines that decide on your behalf

    Search engines and browsers were the old distribution layer. Assistants, agents, and answer engines are the new one — and they only work when your public site exposes clear, consistent signals.

    What it is not

    VibeSignal is not a measure of model safety or prompt injection risk inside your app. It is strictly about passive, public signals: what an automated client can see without logging in.

    Breakdown

    Five categories, twenty points each

    Each bucket caps at twenty points. Together they form the 0–100 AI Signal Score shown beside your trust grade in the scan spotlight.

    Discoverability

    0–20

    Sitemaps, robots references, and whether key entry URLs resolve cleanly for crawlers.

    Content access

    0–20

    Structured metadata and machine-readable cues that help agents summarize or route users.

    Bot access

    0–20

    Robots policy balance: not blocking legitimate discovery while still avoiding obvious spam holes.

    Protocol discovery

    0–20

    Well-known URLs, security.txt-style hints, and other protocol-level breadcrumbs.

    Commerce readiness

    0–20

    Public signals that checkout, pricing, or conversion paths are legible when agents need them.

    Reading the label

    Strong, partial, or weak describes the whole picture

    The headline label is derived from the total score. Use the per-row bars when you want to know whether the gap is discovery, policy, or something more specific.

    • Strong Signal: the site is consistently legible to automated discovery and interpretation.
    • Partial Signal: some buckets are healthy while others leave agents guessing.
    • Weak Signal: critical discovery or access signals are missing or contradictory.

    Workflow

    Use the AI Signals tab in findings review when you want a focused pass

    The full queue still mixes transport, headers, and exposure. The AI Signals filter keeps only VibeSignal-tagged items so you can copy remediation text and track roadmap themes without context switching.

    01

    Run a scan

    Complete a public scan so VibeSignal can evaluate the live response path and HTML surface.

    02

    Open findings review

    Switch to the AI Signals view to see only the VibeSignal category rows with evidence and fixes.

    03

    Copy fix and recheck

    Use Copy fix on remediation text, ship changes, then rerun the scan to confirm the score moved.

    Next action

    Run the scanner against your own site

    The article lands hardest when it turns into a fix list. Scan, close the gaps, and recheck.
