What UTM source should I use for ChatGPT ads?

Pick one convention and stick to it. `utm_source=chatgpt` with `utm_medium=paid` (or `cpc`) keeps ChatGPT ads separate from organic ChatGPT referrals.

Are UTMs case sensitive?

Yes. "Meta" and "meta" show up as different sources in most analytics tools. Use lowercase everywhere.

Do UTMs replace the OpenAI pixel?

No. UTMs label traffic in your analytics; the pixel and Conversions API report conversions back to Ads Manager so bidding can optimize. Use both.
