UTM Link Builder

Add campaign tracking parameters to a URL, with consistent naming, and copy the finished link.

Your link

Page URL

Source (required)

Where the traffic comes from: newsletter, linkedin, google.

Medium (required)

The kind of channel: email, social, cpc, referral.

Campaign (required)

The campaign or promotion this belongs to.

Term (optional)

Paid keywords.

Content (optional)

Tells two links on one page apart.

Tidy the tags: lowercase, with underscores for spaces, so “Spring Launch” and “spring launch” report as one campaign.

Your tagged link

https://example.com/pricing?utm_source=newsletter&utm_medium=email&utm_campaign=spring_launch

Source, medium and campaign set

Use UTM links for links you place on other channels. Don't use them for links between pages on your own site: they overwrite where the visit really came from.
Pick names once and reuse them. Inconsistent tags split one campaign into several lines in your reports.

How to use it

Enter the page you're linking to and fill in the source, medium and campaign. The tool adds utm_ parameters and gives you a tagged link to copy. Analytics tools such as Google Analytics read those parameters to show which campaign sent each visit.

The five parameters

Parameter	Use it for	Example
`utm_source`	Where the traffic comes from	`newsletter`, `linkedin`
`utm_medium`	The kind of channel	`email`, `social`, `cpc`
`utm_campaign`	The campaign or promotion	`spring_launch`
`utm_term`	Paid search keywords	`meta description`
`utm_content`	Which link or version	`header_button`

Keep it consistent

Use lowercase and underscores. Email, email and E-mail are three different values in reports.
Agree names once and reuse them, so one campaign doesn't split across many lines.
Don't use UTM links on your own site. Internal UTM links overwrite the visit's real source.

Do UTM parameters affect SEO?

Not directly, but tagged URLs create copies of a page. Use a canonical link so search engines treat them as one page.
