Google calls the little icon and line of text you see underneath a listing in the local pack, a justification. These are shown for both service businesses and physical stores, and help substantiate why Google has included that listing in the local pack or local finder.
You will see the extracts coming from a few of key sources:
- Customer reviews
- Your website
- Google Posts
- Google auto-generated (non-attributed)
In the example right (under the red line), I used a slight variation on the query to return the same business with a different justification. It appears the non-attributed justification is generated by AI using a combination of sources.
Justifications typically show just above attributes.
And sometimes Google uses information from justifications in a higher priority than the attributes – particularly if the justification comes from a review.
