The name of the campaign or promotion you're running.
The keyword, mostly used in paid search ads.
Tells apart different versions of the same ad or link (A/B tests).
What UTM parameters are and why they matter
UTM parameters are labels appended to a URL that tell Google Analytics (and nearly every other analytics tool) where a visitor came from. A practical example: for the same promotion, the link in your newsletter would carry utm_source=newsletter and utm_medium=email, while the sponsored post on Facebook would use utm_source=facebook and utm_medium=cpc. In your reports you can then see exactly which channel drives the most visits and conversions. Source, medium and campaign are the three essential parameters; term and content are for finer analysis, such as comparing two different banners (utm_content=banner_a vs banner_b).
The rules that keep your data clean
Analytics is case-sensitive: "Newsletter" and "newsletter" show up as two separate sources in your reports. Always use lowercase, replace spaces with hyphens or underscores, and stick to one naming convention over time. This tool automatically encodes special characters (spaces, accents, &) so the link stays valid everywhere. Finally, only use UTMs on external links pointing to your site: on internal links they would restart the session and hide where the visitor really came from.
