Messaging Restrictions

What Are Messaging Restrictions?

When Google Ads AI generates texts for your ads, messaging restrictions can prevent certain terms or topics from appearing. This is especially relevant for regulated industries like healthcare, finance, and law. Knowing these restrictions helps you better control your automatically generated ad copy and avoid disapprovals.

Messaging restrictions are constraints you define in Google Ads to exclude certain concepts or topics from automatically generated ad copy. While term exclusions block individual words, messaging restrictions operate at a higher level: they prohibit entire content concepts, regardless of the specific words the AI might use to express them.

An example: a healthcare company wants to prevent the AI from including medical claims in the ad copy. A term exclusion for the word “cure” is not sufficient, because the AI might use synonyms like “heal” or “relieve symptoms.” A messaging restriction for the concept of “medical claims” blocks all these variants at a semantic level.

In practice, you should use messaging restrictions primarily when your product or industry touches sensitive areas. These include medical promises, financial guarantees, competitor comparisons, or statements about prices that may change. Combine messaging restrictions with text guidelines for positive direction and term exclusions for granular word control. This creates a robust control system for all AI-generated ad content.
