TikTok uses site-wide page events for audience building and behavioral signals, so a pixel restricted to checkout pages loses most of its value.\u003C/p>\u003Ch3>Can I use more than one TikTok Pixel on one website?\u003C/h3>\u003Cp>You can, but it is rarely a good idea. Multiple pixels on the same page produce duplicate events and split your data across assets. Consolidate to one pixel per site and separate campaigns by naming and structure instead.\u003C/p>\u003Ch3>Do I still need the Events API if the pixel works?\u003C/h3>\u003Cp>Yes, in practice. Browser tracking loses events to ad blockers, tracking prevention and abandoned page loads. The Events API recovers those, and is the only way to send conversions that never happen in a browser. Run both with a shared \u003Ccode>event_id\u003C/code> so they deduplicate.\u003C/p>\u003Ch3>Why are my conversion numbers higher than my actual orders?\u003C/h3>\u003Cp>Almost always double-firing. Check for the snippet installed twice, a partner integration running alongside a manual implementation, a confirmation page that fires on reload, or browser and server events without a shared \u003Ccode>event_id\u003C/code>.\u003C/p>\u003Ch3>What is the difference between standard mode and developer mode?\u003C/h3>\u003Cp>Standard mode configures events through TikTok's interface using URL rules and element selectors. Developer mode means calling \u003Ccode>ttq.track()\u003C/code> from your own code. Developer mode is more robust for anything transactional, because it fires on application state rather than on page structure that can change.\u003C/p>\u003Ch3>Does Advanced Matching send my customers' personal data to TikTok?\u003C/h3>\u003Cp>It sends hashed values, not raw ones — the hashing happens before transmission. You still need a lawful basis and appropriate consent for the regions you operate in, and your privacy policy should reflect what you send.\u003C/p>\u003Chr />\u003Cp>Measurement only works when the link between the ad and the landing page stays intact. \u003Ca href=\"https://deepclick.com/\">DeepClick\u003C/a> builds link and routing infrastructure for cross-border advertisers, so click identifiers, redirects and destination logic survive the trip from ad to conversion.\u003C/p>\u003C/div>","https://deepclick.com/resources/blog/tiktok-pixel-setup",{"zh-CN":624,"en":624},[650],{"id":57,"title":651,"site":652,"image":654,"mobileImage":664,"targetUrl":672,"enabled":620,"postDateFrom":673,"postDateTo":674,"updatedAt":675,"createdAt":676},"2026.10.20 Jakarta summit (deepclick)",{"id":18,"key":604,"name":585,"prodHost":605,"testHost":606,"blogPath":607,"docPath":608,"zhPrefix":609,"deployHookTest":610,"deployHookProd":611,"brandAuthor":50,"brandKit":653,"enabled":620,"updatedAt":621,"createdAt":622},{"logoLight":19,"logoDark":19,"primaryColor":617,"accentColor":618,"tagline":619,"wechatName":19,"xhsHandle":19,"wechatQr":19},{"id":655,"alt":656,"updatedAt":657,"createdAt":657,"url":658,"thumbnailURL":19,"filename":659,"mimeType":660,"filesize":661,"width":662,"height":663},1068,"TrafficTalking Jakarta summit 2026.10.20 (en)","2026-09-04T10:44:12.868Z","https://cms-r2.deepclick.com/traffictalking-jakarta-banner-en-9f7ee22f6562.png","traffictalking-jakarta-banner-en-9f7ee22f6562.png","image/png",1565832,2000,400,{"id":665,"alt":666,"updatedAt":667,"createdAt":667,"url":668,"thumbnailURL":19,"filename":669,"mimeType":660,"filesize":670,"width":671,"height":663},1070,"TrafficTalking Jakarta summit 2026.10.20 (mobile-en)","2026-09-04T10:44:23.791Z","https://cms-r2.deepclick.com/traffictalking-jakarta-banner-mobile-en-3ef8e652bbac.png","traffictalking-jakarta-banner-mobile-en-3ef8e652bbac.png",580158,1200,"https://t.me/rrrun_r","2026-09-03T00:00:00.000Z","2026-10-04T00:00:00.000Z","2026-09-04T10:45:05.578Z","2026-09-04T10:45:03.031Z",1789875686713]
