Most companies are flying blind because their web tracking is broken. We just rescued a client from a Google Tag Manager nightmare that could have cost them years of data. Here’s how we did it.
We found incorrect Tag Manager installations on their live site, HubSpot codes that weren’t firing, and former employees who still had admin access.
We had two choices: fix a broken legacy system or start fresh. We went with the ‘Clean Slate’ strategy. We built a brand-new Google Tag container from scratch, but here’s the kicker: we mapped it to their existing Google Analytics ID.
This move preserved all their historical data while killing the technical debt. We migrated the LinkedIn tags, fixed the HubSpot firing issues, and staged everything for production. No data gaps, no lost conversions.
The result? Total visibility. We didn’t just fix the tracking; we documented the entire process in Confluence and cleaned up user permissions to lock down security. Now, their marketing team actually trusts their data.
Stop guessing with your data. If your tag manager looks like a filthy rug, it’s time to clean it up.
