DataSag guides · Updated 27 October 2026
Install DataSag on VitePress
Add DataSag to VitePress through the head array in .vitepress/config.ts or its configured equivalent. Create a project first, then replace the example public key with the key from your dashboard.
Where to put the tracking script
Merge a script tuple into the global VitePress head array. Include the external src, an empty-string defer attribute and the public data-datasag-key. Preserve other head entries, build the documentation and inspect its published HTML. Global config covers ordinary pages generated from that site.
// Merge into the existing .vitepress config.
export default {
head: [["script", {
src: "https://www.datasag.com/tracker.js",
defer: "",
"data-datasag-key": "YOUR_PUBLIC_KEY"
}]]
};The project tracking key is public and belongs in this snippet. Account credentials, provider API keys and database secrets do not. Keep your existing consent choices and only load analytics when your site's policy permits it.
Verify the published installation
- Publish the change to the domain visitors actually use. Open a nested page as well as the homepage.
- In browser developer tools, find one tracker.js script with the correct data-datasag-key value.
- Filter Network requests for /api/track. Confirm that a pageview payload names the path you opened and receives a successful response.
- Open the same DataSag project and choose a date range containing your test. Confirm the page appears before measuring campaigns or conversions.
Avoid this VitePress setup mistake
VitePress also supports page-level head entries in frontmatter and custom theme code. A global script plus page or theme insertion can execute twice. Browser APIs belong in browser interaction code, not the Node-evaluated site configuration or an SSR render.
Keep pageviews separate from scroll, click and engagement events. A page can generate several tracking requests while still representing one visit to that path.
Events and conversions
Use a browser-side Vue handler in a custom component, or a goal attribute on markup you control. Call completed-action events after confirmation, and verify that route changes do not accumulate your custom event listeners.
<a href="/signup" data-datasag-goal="signup_click">Create account</a>This attribute measures a click. To record a completed signup, call window.datasag.track in the application's confirmed success handler. Current plan details determine which event and campaign reports are available.
Setup and troubleshooting recipes
- Verify DataSag analytics on VitePress
Check the rendered script, public project key, browser requests and first pageview before relying on your analytics.
- Fix DataSag analytics not working on VitePress
Trace missing website visits through script placement, project keys, exclusions, consent, network delivery and report filters.
- Fix duplicate analytics pageviews on VitePress
Separate legitimate engagement events from duplicate tracker installations and repeated pageview dispatches.
- Track custom events on VitePress
Add click goals or completed-action events with DataSag's data attribute and browser JavaScript API.
- Track UTM campaigns on your website
Create consistent tagged links and verify that campaign parameters reach your website and DataSag.
- Measure AI referral traffic on your website
Check visits with observable AI referrers and understand the difference between traffic, citations and LLM visibility.
- Configure CSP for DataSag analytics on your website
Diagnose blocked scripts, beacon requests and image fallbacks without disabling your site's Content Security Policy.
- Exclude your own analytics visits on your website
Use DataSag's browser exclusion switch to keep your testing activity out of future tracked visits.
- Load analytics without blocking rendering on VitePress
Choose a non-blocking script placement and verify actual loading behavior instead of relying on a fixed speed claim.
