Advanced Optimization Tips for Google Ad Manager

To truly maximize ad revenue, you need to go beyond the basics. Here are powerful tactics tailored for 2025.

1. Use Key-Value Targeting

Define custom targeting keys such as:

• article_category=tech

• user_type=returning

• scroll_depth=75%

This allows you to serve more relevant ads based on context and behavior.

2. Apply Frequency Capping

Prevent ad fatigue by limiting how often the same ad is shown to a user. Example:

• 3 impressions per user per 24 hours.

3. Optimize for Core Web Vitals

Ads can slow down your site. Optimize lazy loading and responsive designs to maintain:

• LCP under 2.5s

• FID under 100ms

• CLS under 0.1

4. Utilize Video and Interactive Formats

High-impact ad formats like:

• Outstream Video

• Rewarded Video in Apps

• Interactive HTML5 banners

These drive higher CPMs and better engagement than static display ads.
