What does a silent tracking gap cost you?
When a pixel or lead link is no longer visible, ad spend keeps running while measurement does not. Estimate your exposure.
Estimate your blind window
Nothing is sent anywhere. The numbers update as you type.
Silent gaps often go unnoticed for days or weeks.
Lead value at risk in that window
Add your monthly leads and an estimated value per lead to see this figure.
How we calculate: monthly spend ÷ 30 × days unnoticed. This is an illustrative estimate — every business differs.
What opens a blind window
None of these announce themselves. The site keeps loading, the ads keep serving, and the reports keep filling with fewer conversions than the traffic suggests.
- A pixel is no longer visible after a theme or plugin update.
- A WhatsApp or tel: link is no longer visible on the mobile header.
- A form embed changes and the submit event is not firing.
- A tag manager container fails to load, so several tags go unmeasured at once.
