Only 18.5% of clicks came from links carrying UTM parameters — meaning 4 in 5 marketers can't see their true traffic source. We analyzed over 420,000 clicks across 5,700+ tracked links to measure how often links actually get tagged — and which channels bother.

The headline
The vast majority of clicks land on links that were never tagged with UTM parameters. When a link has no UTMs, analytics tools have to guess the source from the referrer — which mobile apps, email clients, and in-app browsers routinely strip — so most of this 81.5% surfaces as "direct" or "unknown."
No UTM tags (untracked source): 342,714 clicks · Tagged with UTM parameters: 77,688 clicks
Who actually tags
Narrowing to just the clicks that did carry UTM parameters, three channels dominate. Email and newsletters lead, with Instagram and Facebook close behind — the places where marketers most deliberately build campaign links instead of pasting a raw URL.
Shares are computed within UTM-tagged clicks only, not across all traffic.
Tag your links so every click reports a real source. Track Link's UTM builder appends consistent parameters in seconds — then shows you who clicks, when, and from where.
Frequently asked questions
In our 2026 analysis of over 420,000 clicks across 5,700+ tracked links, only 18.5% of clicks came from links carrying UTM parameters. The remaining 81.5% landed on links with no UTM tags, meaning the underlying traffic source could not be reliably identified from the link itself.
Without UTM parameters, analytics tools fall back on the HTTP referrer to guess where a visitor came from. Referrers are frequently stripped — by mobile apps, in-app browsers, email clients, messaging apps, and HTTPS-to-HTTP transitions — so untagged traffic often shows up as 'direct' or 'unknown.' UTM tags travel with the click regardless of referrer, which is why tagged links give a far more accurate picture of the true source.
Among the clicks that did carry UTM parameters, email and newsletter traffic led at 29.9%, followed closely by Instagram at 28.6% and Facebook at 24.5%. These are channels where marketers most often build campaign links deliberately, whereas casual shares and pasted links tend to go out untagged.
Use a UTM builder to append utm_source, utm_medium, and utm_campaign before you share a link, and standardize the values so your reports stay clean. Track Link's free UTM builder lets you tag links consistently and then see the resulting clicks by source, device, and location.
