Troubleshoot website engagement custom audience update times

Your custom audience from your website will be updated automatically as people who fall within the rules you specified for your audience navigate to the pages on your website that have the Meta pixel.

For example, if you set your custom audience to only include people who've reached the Add to basket page of your website, it'll automatically add people who navigate there to be part of your audience. If you didn't set any rules, then your custom audience will be automatically updated to add anyone who visits your website.

Note: Targeting options are limited for audiences that include people under the age of 18 in most countries, under 20 in Thailand and under 21 in Indonesia. Learn more about targeting options to reach teens and how this update may affect your ad sets.

Bear in mind that it takes 24 hours after you create your custom audience from your website for it to start collecting data.
