Tracking links that stay consistent

Stop guessing where your traffic comes from. Best UTM .com keeps every parameter clean so your analytics actually add up.

100% private

Everything runs in your browser. No accounts, no tracking, no data sent anywhere — ever.

How it works

Three steps to a trackable link

From raw URL to a fully tagged campaign link without touching a spreadsheet.

1

Paste your URL

Drop in the destination page you want people to land on — a homepage, product page or article.

2

Add your parameters

Set source, medium and campaign. Use the quick chips for common values, or type your own conventions.

3

Copy & launch

Grab the finished link with one click and paste it into your ad, email or social post. Done.

FAQ

Questions, answered

What are UTM parameters?
UTM parameters are small tags added to the end of a URL — like ?utm_source=google — that tell analytics tools where a visitor came from. They let you measure which campaigns, channels and ads actually drive traffic and conversions.
Which fields are required?
No field is strictly required — without a Website URL you get just the UTM parameter string, ready to append to any link. We strongly recommend filling Source and Medium for every link — they're the backbone of channel reporting. Campaign, Term and Content are optional and used for finer segmentation.
Do you store my links or data?
No. Best UTM .com runs entirely in your browser. Nothing you type is ever uploaded, logged or sent to a server, so you can build internal and sensitive campaign links with total confidence.
Why are my values lowercased?
Most analytics platforms treat Google and google as two different sources, which splits your data. Best UTM .com normalizes source and medium to lowercase by default to keep your reports tidy and consistent.
Is Best UTM .com really free?
Yes — the builder is free forever with no sign-up. You only need an account if you later want to save link presets and share naming conventions across your team.
