Attribution Sources
Meta Pixel (Default)
Meta’s built-in attribution uses the Meta Pixel and Conversions API to track conversions. This is the default source and requires no additional setup beyond having a Pixel installed on your website.Cometly
Cometly provides first-party attribution as an alternative to Meta’s tracking. It uses server-side tracking to attribute conversions directly, often providing more accurate data — especially for iOS 14.5+ traffic where Meta’s attribution may underreport.Cometly integration requires a separate Cometly account. Connect it from Settings > Integrations.
Configuring Attribution
Select your attribution source
Under the Attribution section, choose Meta Pixel or Cometly as your primary attribution source.
Where Attribution Applies
Your attribution source selection affects conversion-related metrics in these features:| Feature | What changes |
|---|---|
| AI Insights | Ad rankings are based on conversion data from the selected source |
| Proven Winners | Top-performing ads are ranked by the selected attribution |
| AI Combos | Recommended creative/audience combinations use the selected conversion data |
| Performance Dashboard | Results, Conversion Value, Cost per Result, and ROAS reflect the selected source |
Attribution Toggle
On pages that display conversion data — AI Insights, Proven Winners, AI Combos, and the Performance Dashboard — an attribution toggle lets you switch between Meta and Cometly views without changing your default setting. This is useful for comparing how each source reports the same data.Attribution Windows
During the campaign launch flow, you can configure the attribution window for each campaign. This determines how long after a click or view a conversion is attributed to an ad. Common windows:- 1-day click — conversions within 1 day of clicking the ad
- 7-day click — conversions within 7 days of clicking the ad
- 1-day click, 1-day view — includes both click and view-through conversions within 1 day
