How to Embed a TikTok Feed on BigCommerce (Step-by-Step)
Connecting TikTok, tagging products inside video, and choosing Page Builder versus Script Manager without sacrificing Core Web Vitals.
Video is the one embed type where BigCommerce's choice between Page Builder and Script Manager has a real performance consequence, not just a convenience one: a site-wide script means every page pays for video-player weight, even pages with no gallery visible.
In this article
Step 1: Connect TikTok and sync your catalogue
Authorise TikTok and connect your BigCommerce store so the catalogue syncs, the same first step as every other platform in this series.
Step 2: Place the embed with Page Builder
For video specifically, prefer Page Builder over Script Manager unless the gallery truly belongs storefront-wide. A site-wide Script Manager embed means the video player's JavaScript loads on every page, including ones with no gallery in view, which is pure waste. Page Builder scopes the embed to the templates that actually use it.
Step 3: Tag products and confirm lazy-loading
Tag two to four products per video against your synced catalogue, then confirm off-screen videos load with `preload="none"` and only switch to `auto` once visible. Run PageSpeed Insights on at least three product pages afterward; the full reasoning is in Core Web Vitals impact of UGC widgets.
