When you turn on monetization for your channel, you can choose to share in revenue from ads being served on the Watch Page or in the Shorts Feed. Ads are served through the ads auction, Google Ad Manager, and other YouTube-sold sources. Once you turn on monetization, it may take some time for ads to show up.
The ads on your video are automatically chosen based on context like your video metadata and whether the content is advertiser-friendly.
We regularly monitor and update our systems to deliver the most relevant ads to your videos. However, we don't manually control every ad that shows with your videos, so we can't guarantee that weâll play specific ads.
Ads will not always show on monetized videos. There may not always be an ad available at the time of viewing. If you think there's a problem with ads, learn why ads might not be showing on your videos.
What are partner-sold ads?
Since 2010, YouTube has allowed a few partners to sell ads for the content they place on YouTube. These ads are called "partner-sold ads". To qualify for partner-sold ads, organizations must distribute content across different platforms and have the company infrastructure (including sales forces) to sell ads against their videos.
For partner-sold ads, the partners work directly with advertisers to serve ads on content they own. Advertisers buy ads from these partners so that the ads show up on specific content. This means that partner-sold ads may show even on videos that YouTube considers "not suitable for most advertisers". These partners take full responsibility for the ad placement by working directly with the advertisers. They bear the full risk of putting ads on content advertisers may not think is brand suitable.
Partners can't sell ads against content that is related to tragedies.
