AI Analysis

●MidSolve My ProblemDark Horse

Spots AI referrals when Google Analytics shows 'Direct'—but referrer-based detection is trivial to spoof.

Strengths
  • •Addresses a real gap: no existing analytics tool isolates AI traffic from mislabeled 'Direct' visits
  • •Covers 8+ AI sources (ChatGPT, Perplexity, Claude, DeepSeek, Grok) with structured event payloads
  • •Zero dependencies, no cookies—low-friction drop-in script with optional self-hosted backend
Weaknesses
  • •Purely referrer-based: easily spoofed by redirects, proxy chains, or copy-paste URLs from AI sessions
  • •No IP-based validation or behavioral clustering—high false-positives if someone bookmarks an AI link
  • •Google Analytics 4 already has custom event tracking; this solves a 2–3 line implementation problem

Digital identity pages with traffic quality

This is a link-in-bio take with a useful twist: per-page 'human score' from request fingerprinting, first-click tracking and referrer breakdowns give you more actionable signal than raw view counts. The UI and a Figma-style canvas feel well thought-out, but the idea lives in a crowded market and the fingerprinting/heuristic rules need clearer documentation and opt-out/privacy options before the analytics can be trusted widely.
