Cut Blocking Time by 35% & Restored Google Tag Manager Best Practices
After gaining access to Google Tag Manager at DentalPlans.com, I learned that they had a long-standing “Urgent” (red alert) container quality. During my investigation, I found they had been loading GTM in the footer as a workaround for historic third-party script conflicts, undermining data accuracy and observability.
I prioritized and resolved the issue by restoring GTM to its proper location in the <head> as Google recommends. I also audited our other frontend scripts—including legacy configurations for OneTrust and jQuery—and added configurations in WordPress to help the team rapidly respond to future third-party issues without a deployment.
This effort cut Total Blocking Time by 35% and restored confidence in the quality of our analytics. Stakeholders were kept fully informed of the changes, and the release went live without disruption.
