Where do discrepancies come from?

1

Ad-blockers and browsers

~15-25% of users block tracking scripts. Safari and Firefox limit third-party cookies by default.

2

Consent Mode and GDPR

Users rejecting cookies aren't fully tracked. Without Consent Mode v2, you lose modeled data.

3

Implementation errors

Duplicate tags, missing Enhanced Ecommerce, misconfigured dataLayer — common Shopify issues.

4

No Server-Side Tracking

Client-side tracking is vulnerable to blocks. Server-side bypasses most browser restrictions.

Frequently asked questions

Is my data safe?

Yes. All calculations are performed locally in your browser. We don't send any data to a server or store it in any way.

How accurate are these estimates?

These are estimated values based on the difference between your data sources. Actual loss may vary depending on tracking configuration, industry, and traffic sources.

What can I do to recover this data?

The most effective solutions are: implementing Server-Side Tracking, proper Consent Mode v2 configuration, and Enhanced Conversions in Google Ads. We can help with all of these.
