# What Issues Can Occur if the Invoca Tag Is Set to "Page View" Instead of "Dom Ready" in Google Tag Manager?

> Invoca recommends firing the Tag on "Dom Ready" or "Page Load" in Google Tag Manager — using "Page View" instead can cause inconsistent loading and delayed number swaps.

Invoca recommends setting the Invoca tag's firing trigger to "Dom Ready" or "Page Load."

If the firing trigger is set to "Page View" instead, the tag can load inconsistently, which may prevent phone numbers from rotating on time.

**Applies to:** Invoca Tag configuration in Google Tag Manager
