Every click tracking system does the same three things in sequence. It puts a trackable link in front of a visitor, it logs data the instant that link is clicked, and it forwards the visitor on to the real destination. The differences between one tool and another are about what gets logged and how reliably that handoff works, not whether clicks get counted at all.
How click tracking actually works
A click tracking link almost never points straight at its destination. It points at a tracking domain first, a short link, a bio link, or an ad network's click URL. When someone taps it, the request hits the tracker before it hits anything else. The tracker writes down the event, then issues a redirect, usually an HTTP 302, that sends the browser on to the real page. The whole exchange takes a fraction of a second. It is invisible to the person clicking.
That redirect step is the entire mechanism. Nothing about click tracking requires cookies, device fingerprinting, or JavaScript running on the destination page, because the data is already captured before the destination ever loads.
Redirect based tracking vs JavaScript based tracking
Most click tracking is redirect based, for the reason above: the server logs the event and forwards the request in one step, and it works even if the visitor's browser has JavaScript disabled or blocks third party scripts. A smaller number of tools use a JavaScript onclick handler instead, firing a logging request from the browser the moment a link is clicked, then letting the browser navigate normally. JavaScript based tracking can capture a couple of extra client side details, screen size, for instance, but it fails silently whenever a script is blocked, an ad blocker is active, or the visitor navigates away before the script finishes firing. That failure mode is quiet. Nothing errors; the click simply never gets logged. Redirect based tracking does not have this gap, which is why link-in-bio tools, URL shorteners, and ad platforms default to it.
What gets captured on a single click
- Timestamp, down to the second.
- Referrer: which page, post, or app sent the click, when the platform passes that along.
- Device and browser type, pulled straight from the request's user agent string.
- Approximate location, country and city level, guessed from the IP address at the moment of the click.
- UTM parameters, if the link carries them, which tie the click to a specific campaign or post (a UTM builder is the fastest way to attach these consistently).
- Click ID, when the link originated from an ad platform that appends its own identifier.
Click tracking vs pixel tracking
These two get confused constantly because both show up in the same analytics conversations, but they fire at different moments and measure different things.
| Click tracking | Pixel tracking | |
|---|---|---|
| Fires on | The click event itself, before the destination loads | The page or event loading, after the click |
| Mechanism | A redirect through a tracking domain | A 1x1 image or JavaScript snippet embedded in a page |
| What it tells you | Someone clicked, and where the click came from | A browser rendered a page or fired a scripted event |
| Typical use | Bio links, affiliate links, ad click-through counts | Retargeting audiences, on-page conversion events |
| Commonly blocked by | Broken redirect chains, some in-app browsers | Ad blockers, cookie restrictions, browser tracking prevention |
The practical takeaway is that click tracking is upstream of pixel tracking. A click has to happen, and be counted, before any pixel on the destination page gets a chance to fire.
The failure mode most explanations skip
Click counts are not as literal as they look. Instagram, TikTok, and Facebook open outbound links inside their own in-app browser rather than the visitor's default browser, and that in-app browser can strip or rewrite the referrer, sometimes badly enough that a click tracker cannot tell which post it came from. Worse, some apps prefetch or preview a link's destination before a person has actually tapped it, which can inflate raw click counts with requests no human ever made. A click tracking setup that only counts hits at the redirect, without any way to filter bot and preview traffic, will overstate real engagement, sometimes by a meaningful margin on Instagram-heavy traffic. This is one reason serious link tracking tools separate a raw hit count from a qualified click count.
What click tracking cannot tell you
Nothing past the click is visible. It cannot tell you whether the visitor bought something, filled out a form, or bounced in two seconds. None of that happens on the tracking domain. It happens on the destination site. Measuring what happens after the click is a separate discipline called conversion tracking, and it needs its own instrumentation on the destination page. Treating a click count as a proxy for revenue is the single most common misread of link analytics.
It is also worth being precise about the broader term it sits inside. Link tracking is the umbrella, click tracking is the specific act of logging the click event within it.
Where click tracking shows up in practice
Ad platforms track clicks on every paid placement, appending a click ID that later lets them match a click to a conversion inside their own reporting. Email tools track clicks on every link in a campaign, which is how an open rate turns into a click through rate. Affiliate networks track clicks to attribute a sale to the right partner, often stacking a cookie window on top of the click log so a purchase three days later still counts. Link-in-bio tools track clicks on every link a creator or business puts behind a single page, because a bio link is, structurally, nothing but a page of trackable links pointed at one profile.
Raydar's link pages log the referrer, UTM data, and a first-touch and last-touch cookie for every click a raydar.bio link receives, which is what makes it possible to say a specific post, not just a vague spike in traffic, produced a given batch of clicks. That distinction, one post against a vague spike, is usually the entire reason a business moves off a plain, unlogged link in the first place.
