# Track which call-to-action was clicked

> Use utm_content and utm_term to see which button or link drove a lead.

If the same page has several calls to action, you can record which one a visitor clicked using the `utm_content` and `utm_term` parameters — without disturbing the original source attribution.

## How to do it

On your own on-page links, add `utm_content` (and optionally `utm_term`) to label the call to action:

```text
/pricing?utm_content=sidebar_button
/pricing?utm_content=top_banner
```

Now a lead's record shows not just *where they came from* but *which CTA they responded to*.

## Important: don't override source, medium, or campaign

Only override `utm_content` and `utm_term` for on-page clicks. Changing `utm_source`, `utm_medium`, or `utm_campaign` on an internal link can replace the visitor's original attribution — so a lead that came from a paid ad could lose that history. Keep the first three for how a visitor *arrived*, and use content/term for what they clicked once they were there.
