GA4 can show referral traffic from AI assistants when those visits arrive in the browser. It does not give SEO teams a first-class report for server-side AI crawler fetches and fetch-to-visit correlation.
HitKeep is a better fit when the question is not just how many visits came from ChatGPT, but also which pages AI systems fetched before those visits appeared.
When HitKeep is the better fit
Use HitKeep when the reporting question includes server-side AI crawler behavior, not only browser sessions. GA4 is a browser and app analytics system. It can report visits that arrive with AI assistant referrers, but it does not inspect your edge or origin logs for crawler fetches.
- AI crawler fetch records from CloudFront, nginx, Caddy, app servers, or edge logs.
- AI-referred human visits from browser tracking.
- Correlation between fetched paths and later AI-referred visits.
- Opportunity pages for SEO work.
- Failure hotspots for 4xx and 5xx crawler requests.
- EU or US managed cloud for a quick client pilot.
When GA4 is still needed
You can run HitKeep beside GA4 during a pilot. Use HitKeep for AI crawler visibility and GA4 for Google ecosystem reporting until the client decides what should stay.
- Google Ads integration.
- Query-to-session attribution beyond aggregate Search Console rows.
- BigQuery workflows.
- App analytics.
- Predictive audiences.
- GA4 exploration reports.
What each tool can see
| Signal | GA4 | HitKeep |
|---|---|---|
| AI-referred browser visit | Yes, when the referrer is visible | Yes, through hk.js |
| GPTBot, ClaudeBot, or PerplexityBot fetch | No first-class crawler report | Yes, through AI fetch ingest |
| Custom tracker hostnames | Depends on your tag and proxy setup | Team-level custom domains for hk.js and browser ingest |
| Crawler 4xx and 5xx errors | No | Yes, from forwarded server-side records |
| Fetch-to-visit overlap | No dedicated report | Yes, in AI Visibility correlation |
| Google Ads workflows | Yes | No |
What the setup requires
For CloudFront-hosted sites, use CloudFront AI crawler tracking. For dashboard behavior, use the AI Visibility Dashboard Reference.
- hk.js on the site for browser pageviews, AI-referred visits, goals, and automatic events.
- Optional custom tracking domains when the team wants the browser tracker served from customer-owned tracker hostnames.
- Server-side AI fetch ingest for crawler requests.
Pilot measurement plan
Run both tools for the same site for at least 14 days. Keep GA4 for its existing acquisition and advertising workflows, then use HitKeep to answer the crawler questions GA4 does not cover.
- Confirm hk.js records normal visits and AI-referred visits.
- Forward AI crawler fetches from the edge or origin layer.
- Review fetched paths, crawler families, status codes, and response times.
- Compare correlation pages with GA4 landing pages and Search Console queries.
- Turn crawler errors, high-fetch low-visit pages, and weak conversion paths into the next work list.
Operational integration boundary
HitKeep can send signed site, goal, import, team, and user lifecycle events to external systems with bounded retries and delivery history. This webhook surface is separate from AI fetch ingest and does not send raw traffic or AI crawler records.
