Audience Signal
01 Definition
Audience Signal meaning: A hint you give an automated campaign about who is likely to convert.
An Audience Signal is data you provide to guide machine learning campaigns like Performance Max. You suggest audiences such as your customer lists, interests, or search terms. It is a starting hint, not a strict boundary, so the system may still reach people outside the signal if it predicts conversions.
Why it matters
How Audience Signal fits the work
It helps automated campaigns learn faster by pointing the system toward audiences you already know perform well for your business.
In context
For a Performance Max campaign, you add your past buyers and in-market shoppers as an audience signal to speed up early learning.
Practical note
Because it only guides the algorithm, ads can serve beyond your suggested audiences. Treat it as direction rather than a firm targeting limit.
