Build tracked campaign URLs in seconds
Enter your URL and campaign details and get a correctly encoded UTM tracking link, built privately in your browser.
For the best results: Fill in at least source, medium, and campaign, analytics tools expect all three. Values are encoded automatically, so spaces and symbols are safe. Keep naming consistent (lowercase, hyphens) across campaigns.
Built locally, the URL is never requested or logged. Values are URL-encoded automatically.
What is UTM Link Builder?
UTM Link Builder is a free online utility that builds a correctly encoded campaign tracking URL from your link and UTM values, generated locally and never logged. The conversion runs as plain JavaScript in this tab, so whatever you paste, including anything sensitive, never leaves your device. There is no server call involved at all, no account to make, and no cap on how often you use it.

See it in action
A newsletter link needs campaign tags without breaking the URL's existing parameters.
What you type
https://example.com/page?ref=1 with source "news letter" and medium "email"
What you get
https://example.com/page?ref=1&utm_source=news+letter&utm_medium=email, the existing ?ref=1 preserved and the space properly encoded, plus a note that utm_campaign is still missing for full analytics.
Tip: The builder appends with & when the URL already has a query string, a detail hand-built links regularly get wrong. Fill source, medium and campaign as the minimum set most analytics tools expect.
Use cases
What people use it for
Tag every link in a newsletter so campaign clicks appear separately from organic traffic in your analytics
Build matching tracking links for a paid push across Facebook, LinkedIn and Instagram placements
Create QR-code destination URLs for printed flyers so an offline campaign finally becomes measurable
Who uses UTM Link Builder?
Email marketers
tag each newsletter and automation link so performance is attributable down to the individual send and button
Small business owners
learn whether flyers, socials or the local paper actually send visitors worth the ad spend
Marketing agencies
keep client tracking links uniform across every channel so monthly reports compare like with like
How it works
- 1Vary step 1 by tool shape using the existing FORM_TOOL_IDS set in app/(public)/[category]/[tool]/page.tsx. Form tools get "Set the options for what you need." and text tools get "Paste your text into the box." Where a tool's config makes it easy, name its own inputs instead. Steps 2 and 3 stay shared as they are.
- 2Your browser computes the result instantly. Nothing is uploaded anywhere.
- 3Copy the output; the tool keeps working even offline.
Tips for the best results
- Lowercase every parameter value and use hyphens, never spaces, so one campaign stays one report row
- Keep a shared spreadsheet of approved source and medium names for everyone who builds links
- Use utm_content to separate A and B variants pointing at the same landing page
- Never tag links between pages of your own site
- Paste the finished URL into a browser once to confirm the page still loads before distributing it
FAQ
Frequently asked questions
What do the five UTM parameters actually mean?
utm_source names where the visitor came from, such as newsletter or facebook. utm_medium describes the channel type, like email, cpc or social. utm_campaign identifies the specific push, say spring-sale. The optional pair round it out: utm_term records paid search keywords, and utm_content distinguishes two variants of the same ad or button. Analytics groups sessions by these values, so they decide how readable your reports are.
Why does consistent naming matter so much with UTMs?
Analytics platforms treat Email, email and E-mail as three separate mediums, because parameter values are case sensitive and matched literally. One inconsistent tag splits a single campaign across multiple report rows and quietly understates its performance. The fix is a house convention: lowercase everything, hyphens instead of spaces, and an agreed vocabulary for source and medium that everyone touching links actually follows.
Does the builder change or shorten my original link?
It leaves the destination untouched and simply appends the campaign values as an encoded query string. Spaces and special characters are percent-encoded so the finished URL survives email clients, QR generators and social schedulers without breaking. The page your visitor lands on is exactly the one you supplied. If the long result bothers you, run it through a shortener afterwards.
Are the links and campaign names I type recorded anywhere?
The finished URL is assembled by code executing in your own tab, so unannounced landing pages, client campaign names and launch dates never travel anywhere. There is no request to a backend, no analytics on your inputs and no history kept, and the builder continues assembling links with the connection switched off. Sensitive campaign planning stays exactly where you typed it.
Should I put UTM tags on links within my own site?
No, and this catches a lot of people out. Clicking an internally tagged link restarts session attribution, so a visitor who arrived from a paid ad gets reassigned to your internal banner and the ad loses credit. Reserve UTMs for links that bring people onto your site from somewhere else: emails, ads, social posts, partner pages and printed materials.
What is a UTM link builder used for?
It attaches standardized tracking parameters to a URL so analytics software can report exactly which campaign, channel and creative brought each visitor. Without the tags, most email and social traffic collapses into vague buckets like direct or referral. With them, you can compare a newsletter against a paid ad on actual numbers.
Do UTM parameters affect SEO rankings?
Search engines ignore UTM values when judging relevance, so the tags themselves neither help nor hurt rankings. The genuine risk is duplicate URLs: the tagged and untagged versions of a page can both get indexed. A canonical tag pointing at the clean URL resolves that, and most CMS platforms add one automatically.
Is a UTM builder an AI tool?
No. Building a tracking link is string assembly with fixed encoding rules, and that is precisely what you want here. The same inputs produce the same URL every single time, the result appears instantly, and nothing you enter is sent anywhere for processing. Guesswork has no place in campaign tracking.
Are there any usage limits?
None. Everything is generated locally in your browser, so there is no server cost, no metering, and no daily cap, use it as many times as you like, completely free.
