Study first
Review the ideas behind the questions
Review LinkedIn Ads brand-safety controls before you start. Focus on where lists apply, what the templates allow, and how publisher reports support placement checks.
The Brand Safety hub controls account and ad set levers
Brand safety checks start by reviewing the right Campaign Manager surface and placement type.
- The Brand Safety & Suitability Hub is reached from Plan, then Brand safety.
- The suitability controls tab can add lists, enable lists, and exclude IAB categories.
- Publisher delivery reports can validate list effectiveness and trusted publisher delivery.
In Practice
Start with the placement type
Decide whether the control belongs to profiles and Pages, Audience Network, or CTV Ads.
Use the hub for review evidence
Publisher delivery reports help validate whether list controls worked.
Common mistakes
Uploading one list without checking the placement.
Choose the correct placement type first because list rules differ.
Q&A
Where should brand-safety review start?
Start in Plan, then Brand safety.
What can publisher delivery reports validate?
They validate list effectiveness and trusted publisher delivery.
List rules differ by placement
Profile and Page controls are not the same as Audience Network and CTV controls.
- Profiles and Pages support block lists, not allow lists.
- Profiles and Pages block lists apply to right-rail desktop placements.
- Audience Network and CTV Ads support block or allow lists for partner sites and apps.
In Practice
Do not ask for a profile allow list
Selected LinkedIn profiles and Pages can be blocked, but not used as an allow list.
Keep CTV and Audience Network files separate
CTV Ads and Audience Network-enabled ad set lists must be uploaded separately.
Common mistakes
Treating a profile block list as a publisher list.
Use the profile template for profile or Page URLs and the publisher template for partner inventory.
Q&A
Can one ad set use both block and allow lists?
No. A LinkedIn Ads ad set can only have either a block list or an allow list applied.
Template limits and reports keep controls usable
Brand-safety checks includes file limits, root-domain behavior, deletion effects, and reports.
- List templates must be CSV or TXT files that are 3 MB or smaller.
- Audience Network and CTV lists can include up to 100,000 entries.
- Audience Network block and allow lists operate at the root-domain level.
In Practice
Check the file before upload
A list that fails type, size, entity, or list-type rules is a setup problem.
Use reports to update lists
Publisher delivery reports show where ads appeared and can inform list updates.
Common mistakes
Deleting a list without checking ad sets that use it.
Check affected ad sets first because deleting a list removes that control from those ad sets.
Q&A
Why download the publisher list before building a custom list?
It helps include or exclude publishers that are part of Audience Network or CTV inventory.
