What is the UTM Link Builder?
Build campaign-tagged URLs with UTM parameters for Google Analytics. UTM parameters tag links so analytics tools can show which campaigns, sources and channels bring visitors and sales.
How to use the UTM Link Builder
- Enter your website url, your utm_source, your utm_medium, your utm_campaign and the remaining fields.
- Results update automatically as you type; you can also press Calculate.
- Read the output: campaign url.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Where the UTM Link Builder helps in real life
You are sharing a sale in an email and on Instagram. Separate UTM links show which channel drove more purchases.
You run ads on several platforms and want consistent campaign names. Building every link here keeps reports clean.
Common mistakes to avoid
- Using inconsistent capitalization across links.
- Adding UTM tags to internal links.
- Leaving spaces in parameter values.
- Using vague campaign names.
💡 Practical tip: Never use UTM tags on links within your own website — they overwrite the original traffic source.
Tips for better results
- Use lowercase for every parameter.
- Keep a shared naming list.
- Test links before publishing.
