Available controls
Depending on inventory, targeting can include country, region, city, device, operating system, browser, language, connection and supply source. Use the options actually available for the selected format and partner.
Combine settings carefully
Each additional restriction reduces eligible traffic. Check the traffic preview after changes. Include or exclude audiences where appropriate and avoid starting with several very narrow layers.
Refine with evidence
Start with a practical baseline, compare performance by segment and narrow targeting using sufficient data. A small audience, strict cap or long blocklist may explain low delivery even when the campaign is active.
