Hi there,
You can subscribe to the data provider's data feed for segment and overlap plan, which is usually free for most of the data providers.
Then, you'll be able to see their traits in your AAM instance. You can run a trait to trait overlap report against data provider's traits.
High overlap and low overlap both are useful:
- High overlap tells you that those visitors have been to your web properties. But, you do not have their behavioral info or trait info.
- Low overlap tells that there is an opportunity to increase your reach by onboarding new set of customers for prospecting.
For more info, you can refer to following doc:

Thanks,
