If you cannot tell which post, ad or email brought an enquiry, you cannot improve it. UTM tags fix that. Here is how they work, a naming system that keeps reports clean and the mistakes to avoid.
Short answer: add three tags, source, medium and campaign, to every link you share outside your website, and use the same lowercase names every time. Then Google Analytics shows exactly which channel and campaign brought each visit, and you can spend more on what works.
| Tag | Question it answers | Example |
|---|---|---|
| utm_source | Where did it come from? | facebook, google, newsletter |
| utm_medium | What kind of channel? | paid_social, cpc, email, social |
| utm_campaign | Which push? | diwali_offer_2026 |
| utm_content | Which version? | video_a, button_blue |
| utm_term | Which keyword (paid search)? | bridal_makeup_rajkot |

Use source, medium and campaign every time. Add term for paid keywords and content to tell versions of an ad or link apart.
No. Tagging internal links can overwrite the true source of a visit. Use UTMs only on links that point to your site from elsewhere.

Analytics is case-sensitive. Use one lowercase style with underscores for every tag.
