Free UTM code generator for Google Analytics.

Yes. Download the free Excel template or the CSV for Google Sheets on this page: paste the landing page, source, medium and campaign, and the tagged URL builds itself with a formula that lowercases values, replaces spaces and handles links that already contain a question mark.

Yes, completely, with no signup and no limit. Links are built in your browser and nothing you type is sent to us; your recent links are saved only on your own device, with a CSV export.

Small labels appended to a link — utm_source, utm_medium, utm_campaign — that tell your analytics where a visit came from. Without them, a click from your Instagram bio and a click from a paid ad can look identical in reports; with them, you know which effort actually produced the inquiry.

Source is where the click happened: google, facebook, newsletter. Medium is what kind of channel it was: cpc for paid clicks, social for organic social, email for mailers. Campaign is which specific push: black_friday, spring_sale. Together they answer where, how and why.

Because analytics tools treat "Facebook", "facebook" and "FaceBook" as three different sources, silently splitting one channel into three rows. The builder normalizes for you so reports stay in one piece.

No — internal UTMs overwrite the visitor's original source, destroying the very attribution you built. Use them only on links that live outside your site: ads, social posts, emails, QR codes, directories.

In Ads Manager, open the ad, scroll to Tracking and paste the parameters into the URL parameters field rather than into the website URL. Meta's dynamic values, such as {{campaign.name}} and {{ad.name}}, fill in each ad's real names automatically, so one string tags every ad correctly.

Not for Google Analytics. With auto-tagging switched on, Google Ads adds a gclid to every click and GA4 uses it to report the campaign, keyword and cost. Manual UTMs on Google Ads are useful when another analytics tool or CRM needs to read the campaign.

No. Search engines ignore them for ranking, and a canonical tag on your page tells Google which URL to index. The only rule is not to put UTMs on links between your own pages, which breaks attribution rather than rankings.

GA4 sorts every visit into a default channel using its source and medium. When the pair matches none of Google's rules (for example utm_medium=qr, print or chat), the visit is filed as Unassigned and is easy to overlook. Use a standard medium such as social, email, cpc, display, referral or affiliate, or create a custom channel group in GA4 for QR and print. The builder above shows the channel before you share a link.

Paste it into the link checker on this page. It lists the tags, shows which GA4 channel the visits land in, and flags what splits or loses data: capitals, spaces, missing source, medium or campaign, and repeated tags.

Yes. Switch the builder to "Several channels", enter the landing page and campaign, and tick the channels: Facebook and Instagram ads, posts, LinkedIn, TikTok, YouTube, email, partner sites, QR codes. You get one correctly tagged link per channel, each with the GA4 channel it will land in, to copy one by one, copy all into a spreadsheet, or download as a CSV.

Fill in the builder, then use "Share this setup with your team". It copies a link that opens the builder already filled in with your landing page, campaign and tags, so colleagues and clients only change what they need. Nothing is stored on our side: the setup lives in the link itself.

The campaign ID parameter. GA4 uses utm_id to match visits with cost data you import from ad platforms that Google doesn't connect automatically. It's optional: open "Keyword and campaign ID" in the builder to add it. Unlike the other tags it is kept exactly as typed, because IDs are case-sensitive.

In Google Analytics 4: Reports → Acquisition → Traffic acquisition, or filter any report by session source/medium. Visits arrive labeled exactly as you tagged them.

Urchin Tracking Module. Urchin was the analytics company Google bought in 2005 and turned into Google Analytics; the utm_ parameters kept the name. Today they're a standard that GA4, Matomo, HubSpot and most marketing tools read.

Yes. UTM parameters are part of the link, not the website, so they work on any platform. The analytics on the destination site (GA4 or another tool) reads them when the visitor arrives.
