Precision YouTube Advertising

The path to brand success in online video starts with aligning with the right content. When your ad is targeted against the right content, in the right context, you’ll achieve immediate media impact and long-term brand value. Here’s how it works.

Discovery & Relevancy

Zefr discovers every video uploaded to YouTube. We then analyze the meta-data to determine the context of the video and if it could be relevant for a brand to advertise against.

Forecasting Performance

Our proprietary model determines the forecasted amount of views and impressions so you can effectively scale the reach of your campaigns.

Each video goes through a rigorous approach that includes both technology and human review to ensure only the most premium videos are included and targeted in Zefr campaigns.
