This means that you should run both and deduplicate with a shared event_id for the best results.&nbsp;<\/p>\n\n\n\n<p>If done well, all of these workflows can give you fewer missed conversions, stronger retargeting and <a href=\"https:\/\/leadsbridge.com\/blog\/how-to-use-facebook-lookalike-audiences\/\">lookalikes<\/a>, and even help the algorithm better learn what you are after.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"1-conversions-api-vs-pixel-only-setups\">Conversions API vs. Pixel-only setups<\/h2>\n\n\n\n<p>Why does setting up both outperform a system that only uses Pixel? Here are a few good reasons why a complete Facebook API advertising is superior:<\/p>\n\n\n\n<p><strong>1. Captures conversions that the Pixel misses.<\/strong>&nbsp;<\/p>\n\n\n\n<p>You don&#8217;t want any \u201cghost conversions\u201d per se, and want to focus on steadier optimization.<a href=\"https:\/\/www.facebook.com\/business\/help\/AboutConversionsAPI?utm_source=chatgpt.com\"> <\/a>So, blockers, poor connections, or private browsing can prevent Pixel from working. However, CAPI advertising lets you catch the same events from your server.&nbsp;<\/p>\n\n\n\n<p><strong>2. Cross-device and cross-channel clarity.<\/strong>&nbsp;<\/p>\n\n\n\n<p>Customers research on mobile and buy on desktop or by visiting the physical store. Conversions API lets you connect these touchpoints using server-verified identifiers and offline events.<\/p>\n\n\n\n<p><strong>3. Subscription and downstream events.<\/strong>&nbsp;<\/p>\n\n\n\n<p>Pixels can\u2019t see renewals, upgrades, cancellations, or CRM stage changes. However, Conversions API can. This means you can optimize for tangible business outcomes.<\/p>\n\n\n\n<p><strong>4. Better match quality and more accurate audiences.<\/strong>&nbsp;<\/p>\n\n\n\n<p>You want to hash all your first-party identifiers and know about server-side event. Here\u2019s what this roughly looks like:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" width=\"1024\" height=\"538\" src=\"https:\/\/leadsbridge.kinsta.cloud\/wp-content\/uploads\/2025\/10\/image-3-1024x538.png\" alt=\"server-side event tracking\" class=\"wp-image-50482\" style=\"width:468px;height:auto\" srcset=\"https:\/\/leadsbridge.kinsta.cloud\/wp-content\/uploads\/2025\/10\/image-3-1024x538.png 1024w, https:\/\/leadsbridge.kinsta.cloud\/wp-content\/uploads\/2025\/10\/image-3-300x158.png 300w, https:\/\/leadsbridge.kinsta.cloud\/wp-content\/uploads\/2025\/10\/image-3-768x404.png 768w, https:\/\/leadsbridge.kinsta.cloud\/wp-content\/uploads\/2025\/10\/image-3-800x420.png 800w, https:\/\/leadsbridge.kinsta.cloud\/wp-content\/uploads\/2025\/10\/image-3.png 1096w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/id5.io\/news\/first-party-ids-and-identity-resolution-methods-explained\/\" target=\"_blank\" rel=\"noreferrer noopener\">Source<\/a><\/figcaption><\/figure>\n<\/div>\n\n\n<p>This expands your Event Match Quality, which in turn improves your attribution, <a href=\"https:\/\/leadsbridge.com\/blog\/cookieless-retargeting\/\">retargeting<\/a>, and lookalikes.&nbsp;<\/p>\n\n\n\n<p>Meta offers a ton of great strategies for event tracking, such as event deduplication (as a best practice) and <a href=\"https:\/\/www.facebook.com\/business\/help\/1624255387706033?id=818859032317965\" target=\"_blank\" rel=\"noreferrer noopener\">even tools for testing your server events<\/a>.<\/p>\n\n\n\n<p><strong>5. Reliability and redundancy.<\/strong>&nbsp;<\/p>\n\n\n\n<p>Sometimes, the Pixel fails to operate. Conversions API, however, still records the conversion. Running both delivers the most complete coverage.&nbsp;<\/p>\n\n\n\n<p><strong>6. Feeds Meta\u2019s optimization engine.<\/strong>&nbsp;<\/p>\n\n\n\n<p>Server-verified events give Meta\u2019s models stronger signals, particularly for lower-funnel actions (purchases, qualified leads).
