Choose the right scope
Use global blocklists for domains, apps, placements or IPs that should never serve across your DSP. Use campaign controls when a source is simply unsuitable for one advertiser. Reports support direct placement blocking.
Source-level settings
Tune filters by source. If a per-campaign filters-off option is available, use it only with a clear understanding of the risk and advertiser requirements. Manual lists supplement rather than replace automated protection.
Maintain your lists
Review old entries and allowlist exceptions periodically. Long lists, strict filters and overlapping exclusions can silently reduce delivery. Record why each broad exclusion was made.
