Outbound Link Tracking: How to See Which Links Send Visitors Away

Published June 3, 2026 • statpx Team • 6 min read • Technical

Standard analytics tells you which of your pages people visit. It tells you almost nothing about the links that take people off your site. Yet every affiliate link, every "buy now" button that points to a partner store, and every citation to an external source is a moment where a visitor leaves — and that's exactly the kind of action you want to measure. Outbound link tracking fills this blind spot.

Why Pageviews Miss Outbound Clicks

A pageview is recorded when a page on your domain loads. When a visitor clicks a link to another domain, no new page loads on your site, so nothing gets recorded. The browser simply navigates away. From your analytics' point of view, that visitor just… ended their session.

This matters more than it first appears. If a blog post's main purpose is to drive clicks to a product page on a different domain, your pageview report makes that post look like a dead end — high traffic, a quick exit, and no obvious value. In reality it might be your single best referrer. Without outbound tracking you can't tell the difference between a page that fails and a page that does its job perfectly by sending people elsewhere.

How Outbound Link Tracking Works

Outbound link tracking attaches a click listener to links that point to external domains. The instant a visitor clicks one, the tracker fires a small event — recording the destination URL, the page the click came from, and a timestamp — before the browser navigates away.

The technical challenge is timing: the browser may unload the page before the tracking request finishes. Modern trackers solve this with the navigator.sendBeacon() API, which guarantees the request is sent even as the page is unloading. This is the same mechanism that makes reliable custom event tracking possible.

The basic pattern

// Conceptually, this is what a tracker does for every link click
document.addEventListener('click', e => {
  const a = e.target.closest('a');
  if (!a || !a.host || a.host === location.host) return;
  // External link — record it before the browser leaves
  navigator.sendBeacon('/collect', JSON.stringify({
    type: 'outbound',
    url:  a.href,
    from: location.pathname
  }));
});

With statpx, you don't write any of this. Outbound link clicks are captured automatically by the standard tracking snippet — the same one-line script you already paste into your site. No data attributes, no manual tagging of individual links.

Reading Your Outbound Click Data

Once outbound clicks are flowing in, the most useful view is a simple ranked list of destinations and how often each was clicked:

Destination	Clicks (30d)	Top source page
partner-store.com/product	1,284	/best-tools-review
docs.example.org	612	/getting-started
twitter.com/yourbrand	338	/about
app.affiliate.net/signup	205	/pricing-comparison

This table answers questions a pageview report never could: Which review page actually drives affiliate clicks? Is anyone clicking the documentation link you added to your onboarding page? Are visitors leaving for your social profiles or your competitors?

Tip: Pair outbound clicks with the source page. A page with 5,000 views and 1,200 outbound clicks has a 24% click-through rate — a strong signal that the page is doing its job. A page with 5,000 views and 12 outbound clicks may have a broken or poorly placed link.

What to Do With the Data

Validate affiliate and partner pages: Confirm that pages designed to send traffic out are actually doing it. Low outbound rates on a "money page" point to weak placement or unconvincing copy.
Find your accidental exits: If a high-traffic page leaks clicks to an unexpected external site, you may have a misplaced link or an ad that's cannibalizing your audience.
Reframe "bounces": A page with a high bounce rate but a high outbound click rate isn't failing — visitors are doing exactly what you wanted. Outbound data rescues these pages from looking like failures.
Prioritize content updates: The pages generating the most outbound clicks to revenue destinations deserve your best ongoing attention.

The Bottom Line

Your most valuable page might be one your standard analytics treats as a dead end. Outbound link tracking turns "the visitor left" into "the visitor clicked through to your partner store" — a completely different story. If any part of your site exists to send people somewhere else, whether that's an affiliate link, a documentation portal, or a checkout on another domain, you need to measure those clicks. Track them alongside content performance to see the full value of every page, not just the traffic it keeps.
