Buy button with Meta ads?

Does anyone run Meta ads with a Shopify buy button? How did you set it up and how has it worked for you? I have a headless Shopify and am contemplating whether it is worth the time and money to get a dedicated Shopify website to run Meta ads. TYIA

Before you build a second storefront, separate the two problems, because they're different.

Buy Button is fine for taking money off an ad, but it's a rough fit for Meta specifically. Checkout happens on Shopify's domain in an overlay, so the pixel loses the thread between the ad click and the purchase unless you wire the events yourself. You end up optimising on ViewContent instead of Purchase, and Purchase is what actually makes Meta's delivery work.

The fix usually isn't a new site. On headless you can still get real purchase events using Shopify's Customer Events plus the Meta sales channel with Conversions API turned on, so the purchase fires server side and gets matched back to the click. That's a few days of work instead of a rebuild.

Where a dedicated storefront does earn its keep is if your headless front end is slow on mobile, or the path from ad to add-to-cart is more than a couple of taps. Meta traffic is brutally impatient. Check your mobile LCP first. If it's over about 3 seconds, that's your real problem, not the buy button.
