Automated Advanced Matching
Auto-advanced matching (AAM) uses customer-provided information to associate them with conversion activity for better ad metrics. This feature ingests your site to collect relevant match keys, whether found in plaintext or within forms referenced by the Reddit Pixel. When enabled, this data will be normalized and hashed with SHA-256 before the Pixel receives it.
AAM automatically collects email addresses and phone numbers displayed on the webpage and those typed, pasted, autofilled, or otherwise entered by users. The Pixel must not be placed on a page where any data type you’ve enabled is displayed or entered prior to proper consent or notification being granted.
Ensure your usage complies with our services agreement and any applicable laws. Set up Limited Data Use to help you meet your compliance needs.
By default, this feature is turned off. We strongly recommend enabling it to increase event attribution and minimize signal loss, especially if you can’t edit your site’s code.

Before you start
- Install the Reddit Pixel. This should be placed on pages where users may provide their phone number or email address with their consent. You can install the Pixel directly or with Google Tag Manager or another supported partner.
- Ensure the Reddit Pixel is in a fillable form on your webpage. The Pixel must be able to find the match key on the page to collect it. Make the user’s phone number and/or email address visible on pages.
Set up AAM

Things to know
- This feature is only available for the Reddit Pixel, not the Image Pixel or Conversions API (CAPI). It must also be placed in non-sandboxed environments. iFrames, like those used for Shopify sites, aren’t supported.
- Only email address and phone number match keys are supported.
- Even with AAM enabled, it’s strongly recommended to share match keys directly when possible. Learn how to integrate the Pixel.
- It may take up to 24 hours for data collected to appear in the Events Manager.
