If your Twitter Pixel isn’t tracking conversions, start by verifying that the Pixel ID is correctly installed on your site’s key pages, especially your conversion pages. Use the Twitter Pixel Helper to confirm that it’s firing properly. Check that your event setup matches the actions you want to track, such as purchases or sign-ups. If your website has undergone recent updates, ensure the Pixel configuration is still accurate. Also, keep in mind there might be a slight reporting delay in Twitter Ads. If the issue persists, reach out to Twitter Ads Support for additional guidance and troubleshooting assistance.
