## Frequently asked questions

### What are UTM parameters?

UTM parameters are tags added to a URL (source, medium, campaign, term, content) that analytics tools use to attribute traffic to specific campaigns and channels.

### Do UTM links affect SEO?

UTM parameters are for analytics on outbound links you share; use canonical tags on your own pages so parameterized URLs are not indexed as duplicates.
