Why did ads appear on my ad unit and then stop?

This article is intended for publishers who noticed impressions for a short time and think something is wrong.

Advertisers choose placements themselves

Advertisers independently:

• include ad units
• exclude ad units
• test placements
• optimize campaigns

Because of this, ads can appear and later stop showing.

Why an advertiser may stop showing ads

This is a normal optimization process. Common reasons include:

• Testing period finished
• Better performance found elsewhere
• Audience mismatch
• Campaign budget redistribution
• Targeting adjustments (GEO or language)
• Bid lowered below competition
• Campaign paused or completed
