Drop in Shopify Sessions vs Meta Clicks – Not Aligned Despite Correct Setup

Technical Q&A

1

Hello everyone,

I’ve recently opened a new Shopify store and noticed a consistent discrepancy between Meta Ads clicks and Shopify sessions. Here’s an example with rounded numbers:

  • New store: Meta: 100 outbound clicks / 50 visits → Shopify: 50 sessions

  • Other stores I manage: Meta: 100 outbound clicks / ~90 visits → Shopify: ~90 sessions

So while other stores track normally, this new store shows a big drop (about half of the expected sessions).

What I’ve checked already:

  • Same settings in Meta + Shopify (no differences found).

  • Page speed and theme are optimized.

  • Business Manager assets linked correctly.

  • Pixel event quality is 7.5+ with no duplicates.

  • Tested enabling/disabling cookie banner or pop-ups (no impact).

  • Different ad accounts pointing to the same domain show the same behavior.

  • A friend’s store has had the same issue for months, unresolved even after Meta support calls.

Hypotheses so far:

  • Could this be related to Shopify’s session counting logic?

  • Business Manager–level filtering or Meta in-browser tracking blocking sessions in certain regions?

  • Something related to Cloudflare/IP filtering (I know Spain had issues last year)?

At this point I’ve ruled out the usual “basic” troubleshooting. Has anyone experienced the same and found a solution or deeper cause?

Thanks in advance for any insights!

I’m having the same issue. Did you find a fix for it?

I think this may help

  1. Bot Clicks Filtering: Shopify has identified and removed bot clicks retroactively, which might affect the reported click numbers.

  2. Click Timing: If a click occurs after the data processing window for the current billing cycle, it will be billed in the next cycle but attributed to the previous cycle’s impression.

  3. Community Discussions: There are several discussions in the Shopify Community about similar discrepancies, suggesting that this might be a common issue.
