Hi there,
Thanks for reaching out! I'm happy to give you some initial thoughts and guidance on the Meta Ads attribution issue you're seeing. It's definitely frustrating when your lead tracking goes awry, especially after putting in the effort to set up Conversions API.
I've seen similar things happen before, so hopefully, we can get to the bottom of it. I've detailed a few possible causes and actionable solutions based on my experience.
We'll need to look at your CAPI setup...
First thing I'd do is really double-check your Conversions API setup from top to bottom. I remember one client, a SaaS business, had a similar head-scratcher. They'd made some changes to their website, and seemingly, everything was still firing in the Event Manager. All the events where showing with the correct parameters, nothing failed, so they assumed everything was still working fine.
However, what they discovered was that a slight glitch had crept into the pixel setup *after* the update. The events were firing but the data wasn't quite making its way back to the ads correctly.
I know it sounds basic, but triple-check that your pixel is still correctly installed on all relevant pages, including landing pages and thank you pages. Also, give the events a test run yourself to make sure the data is flowing as expected. Use the Meta Pixel Helper Chrome extension to check the parameters.
Make sure all the right parameters are being passed with each event like click ID. Have a look through your website code, your tag manager, and your e-commerce platform if you're using one to make sure they are all sending the right info. Maybe something small broke in one of these parts.
I would also suggest comparing your CAPI event parameters with your Meta pixel parameters, there could be subtle differences that are throwing off the attribution. I know that some of these parameters are kinda fiddly!
I’d check for discrepancies between your website’s timezone and your ad account’s timezone. Mismatched timezones can cause reporting errors. Make sure they're both set to the same timezone.
I'd say you should check your Attribution Window Settings...
Alright, so if the CAPI set up checks out and the events and parameters are being fired, I'd suggest checking the attribution window settings at the ad set level. Meta are always messing with these so it might be worth having a look just in case.
Sometimes Meta resets these settings during updates, and it could be a really simple fix. Maybe you've changed your ad set settings slightly in the past, or one of your team members has. Make sure everything is still correct, especially when you have lots of people working in the same account.
I think the default is something like 7 days click-through or 1 day view-through now, but maybe you could experiment and widen it temporarily to see if any leads are showing up with a longer delay. A wider window might capture more leads that are converting outside the default timeframe.
Make sure you have the correct attribution setting selected. It could be that you're looking at the wrong setting on Meta ads manager. Check that you're viewing your preferred attribution model. Some people prefer first click, some prefer last click etc.
I think its worth having a look at this and seeing whether it's a quick fix as it might just work.
You probably should review your CRM Integration...
Right, so if that's not working, then I'd probably have a look at your CRM integration if you have one. Have a thorough review of your CRM integration settings. Check that the integration is active and that all the data fields are mapped correctly.
See whether your CRM integration is properly set up and communicating with Meta. Disconnect and reconnect it to refresh the link.
I recall working with a B2B software client, where we generated 4,622 registrations at a cost of $2.38 per registration using Meta Ads. It's worth really checking all these things from top to bottom and see whether they all match up and that your CRM is also sending the events correctly.
You'll need to look at the latest iOS/Privacy Updates...
It's also possible that this is due to some of the recent iOS and privacy updates. I'd suggest checking that you have the latest version of the Meta SDK installed. And have a look at your privacy settings to make sure you are still aligned with the user's preferences for data collection. It might be worth having a look through the Meta documents and guidelines to check these settings and make sure everything is compliant as it can be.
Right, so these are just some of my initial thoughts, hopefully, you found them useful.
I've detailed my main recommendations for you below:
| Recommendation | Action |
|---|---|
| Double Check Your CAPI Setup | Verify pixel installation, event triggers, and parameter accuracy across website code, tag manager, and e-commerce platform. Compare CAPI and Meta pixel parameters for discrepancies. Ensure website and ad account timezones are aligned. |
| Check Your Attribution Window Settings | Review attribution window settings at the ad set level. Experiment with wider attribution windows to capture more conversions. Confirm correct attribution model is selected in Meta Ads Manager. |
| Review Your CRM Integration | Check CRM integration settings for activity and accurate data field mapping. Reconnect the CRM integration to refresh the link. |
| Assess iOS/Privacy Updates | Install the latest version of the Meta SDK. Ensure privacy settings align with user preferences for data collection. Review Meta documents and guidelines for compliance. |
I hope you find that table helpful! Hopefully, that all makes sense.
