Do Link-in-Bio Tools Like Linktree Break Influencer Tracking Links?

How a link-in-bio page actually works

A link-in-bio tool — Linktree, Beacons, Milkshake, Stan Store and similar — solves one specific problem: Instagram, TikTok and most other platforms only allow one clickable link in the bio field. The tool replaces that single link with a landing page full of buttons, each pointing to a destination the creator has typed in themselves — a product page, a YouTube video, or an influencer platform's tracking link. Technically, it's nothing more than an ordinary webpage with a set of <a href="..."> links. When someone taps a button, the browser navigates to exactly the URL in that href attribute — including everything after the question mark.

That means a link-in-bio tool doesn't, by itself, invent or delete anything in the URL the creator has pasted in. The risk isn't in the forwarding step — it's in whatever extra layer the tool adds on top, particularly if the tool has its own optional UTM tagging switched on.

Does the click ID and UTM parameters survive the trip?

An influencer tracking link typically carries three layers of information: the destination address, a click ID or referral parameter that identifies the specific creator, and usually a set of UTM parameters for reporting. See the full walkthrough in how influencer tracking actually works. The click ID is what a commission actually gets tied to — not the UTMs. As long as the creator pastes the whole tracking URL, parameters intact, as the destination of their Linktree button, there's no technical reason any part of it should go missing along the way: the tool sends the browser on to exactly the string that was in the field.

The only place this can genuinely go wrong is if the tool itself rewrites or adds something on top of the URL — which is precisely what Linktree's own UTM feature does, if it's switched on.

Linktree's own UTM auto-tagging — what it actually changes

From Linktree's own Help Center: the feature is available starting on the Pro plan and is set up on the Links page, under the Analytics Integrations tab, by toggling on "UTM Parameters." The default values, per the same source, are utm_medium=social and utm_source=linktree — and the purpose is stated explicitly: "By default, parameters are set so Google Analytics shows all traffic from Linktree under 'Social' data", meaning all Linktree traffic is meant to appear as social traffic in Google Analytics by default, not as a referral. That's a deliberate design choice on Linktree's part — not a bug — and it solves a different, well-known problem: without it, Linktree traffic often lands incorrectly in the Referral bucket of the Acquisition report, with linktr.ee as the source, instead of being recognized as social traffic.

The collision risk: two layers of UTM tagging on the same link

This is where the practical problem for an influencer campaign specifically shows up. If the creator's tracking link already carries its own UTM parameters — for example utm_source=instagram&utm_medium=influencer&utm_campaign=autumn-launch-2026, set by the influencer platform following the convention covered in UTM parameters for influencer campaigns — and the creator also has Linktree's own UTM feature switched on, Linktree's default values get added on top of the link as a second, duplicate set of parameters with the same names. Linktree's own documentation doesn't describe what happens when the feature is enabled on a link that already carries its own UTM parameters — this isn't a confirmed Linktree-specific behavior, but a general, well-established property of URL query strings: when the same parameter name appears twice in one URL, most systems, including Google Analytics, only have one value to work with — typically the one added last. In practice, that can mean a campaign's own utm_source=instagram gets overwritten by Linktree's utm_source=linktree in reporting, while the click ID — which Linktree's UTM feature doesn't touch, because it only sets utm_source, utm_medium and utm_campaign — still passes through unchanged, so the commission is still correctly attributed to the creator.

Linktree is documented — the other tools are structurally the same, but not individually verified

Every link-in-bio tool solves the same underlying problem the same basic way: a landing page with outbound buttons pointing at a URL the creator has entered. That part of the mechanism doesn't depend on which tool is used. What does vary is whether the tool — like Linktree — also offers its own optional auto-tagging on top of the link, and if so, with which default values. Linktree is the only one of these tools where that's publicly documented in this level of detail. Check the specific tool in use for an equivalent setting before assuming it behaves identically.

What can actually go wrong — summarized

• The click ID and commission tracking itself — survives, because none of the known auto-tagging features touch any parameter name other than utm_source, utm_medium and utm_campaign.
• UTM reporting in Google Analytics — can get distorted if the tool's own auto-tagging is switched on top of a link that already carries its own UTM values.
• The destination itself — is never changed by the tool; it's always the URL the creator typed in.

How this fits with other tracking-loss mechanisms

A link-in-bio tool's UTM collision is a reporting-layer problem, not a tracking-loss mechanism in the sense covered elsewhere in the Academy. It's worth distinguishing from three genuinely different causes of a similar-looking symptom: an ad blocker matching the tracking domain itself and dropping the request outright, covered in do ad blockers break influencer and affiliate tracking links; a customer's browser or in-app environment failing to carry a UTM parameter through to Google Analytics at all, covered in why influencer sales don't show up in Google Analytics; and the discount-code alternative that sidesteps link-based tracking, and therefore this whole class of problem, entirely — see discount codes vs tracking links. None of those three mechanisms are specific to a link-in-bio tool; the UTM collision described in this article is.

Worked example (hypothetical)

The figures below are illustrative and invented for this purpose — not a real Make Influence customer case, and not an actual measurement.

Assume a creator on a campaign generates 500 clicks from their Linktree link over a week, and the link carries the influencer platform's own utm_source=instagram&utm_medium=influencer plus a click ID. The creator also has Linktree's own UTM feature switched on from earlier. In Google Analytics, the report shows all 500 clicks under "Social / linktree" — not under "Influencer / instagram" — because Linktree's values won the collision. Had only the influencer platform's own UTMs been used, the same 500 clicks would have been grouped correctly under the right campaign in the report. In both cases, the resulting orders remain correctly attributed to the creator in the commission statement, because that's built on the click ID, not the UTM values — but the 500 clicks are effectively invisible in the campaign report the marketing team actually looks at.

Decision framework

• IF you're using Linktree for an influencer campaign and the tracking link already has its own UTM parameters → turn off Linktree's own UTM feature for that link, or don't activate it account-wide.
• IF you're using a different link-in-bio tool → check the tool's own settings for an equivalent auto-tagging feature before assuming it doesn't have one.
• IF you're unsure whether the parameters survive → click the button yourself from the tool's own landing page and look at the full URL the browser lands on — that's the fastest way to confirm behavior for the specific tool and account in use.
• IF commission tracking is your main concern → it isn't at risk from this mechanism by default, because the click ID isn't one of the parameters any known auto-tagging feature touches.

Common mistakes

• Assuming the link-in-bio tool is the cause when a campaign's numbers look wrong in Google Analytics — the cause is almost always a setting inside the tool itself, not a forwarding failure.
• Switching on the tool's own UTM feature without checking whether the link already has its own UTM parameters.
• Concluding the commission is wrong because the Google Analytics report looks off — the two systems read different parameters, and one can be affected without the other.
• Assuming a tool other than Linktree behaves identically, without checking its own settings first.

Make Influence's operational perspective

At Make Influence, we haven't observed this collision as a widespread source of errors in our own campaigns — but the mechanism behind it isn't speculative; it follows directly from how URL query strings and Linktree's own documented feature work. Our recommendation for brands and creators using a link-in-bio tool as part of a tracking setup is the same one that applies to the rest of the attribution chain: keep UTM tagging to a single source of truth. Let the influencer platform's own link be the final authority, and don't let the link-in-bio tool's own, generic auto-tagging overwrite something that's already set up correctly for the campaign.

FAQ

Does Linktree or a similar tool break the tracking link itself?

No. The tool forwards to the URL the creator pasted in, unchanged. What can go wrong is the tool's own optional UTM feature, if it's switched on on top of a link that already has its own UTM parameters.

Does this affect commission tracking?

Usually not. The click ID — what a commission is actually tied to — isn't one of the parameters Linktree's documented UTM feature touches.

Are Beacons, Milkshake and Stan Store just as safe as Linktree?

The core mechanic (a landing page with outbound buttons) is structurally the same. But only Linktree's own auto-tagging feature is publicly documented at this level of detail — check the specific tool in use for an equivalent setting before assuming identical behavior.

How do I check for myself whether the parameters survive?

Click the button from the tool's own landing page and look at the full URL in the browser's address bar after the redirect. That's the most reliable way to confirm behavior for the specific account and link.

Should I avoid link-in-bio tools for an influencer campaign?

No, there's no reason to. The risk sits in one specific setting — the tool's own UTM auto-tagging, if it exists and is switched on — not in the concept itself.

Does the bio-link page's own address change if the creator changes their platform username?

No. A link-in-bio page has its own, independently chosen address (e.g. linktr.ee/username), separate from Instagram's or TikTok's own username — so it isn't affected. What can go stale is a button inside the page pointing at a profile URL.
