📈 Viewability Standard: Advertisers pay up to 4x higher CPMs for ad units that maintain 70%+ Active View viewability for at least 3 seconds.

Top 3 Highest-Performing, Safe Ad Placements

1. Under the First Paragraph (In-Article Unit)

Placing a responsive display ad immediately below your opening hook paragraph captures maximum attention while the reader is fully engaged. Maintain 25px top and bottom margins to prevent accidental touch taps on mobile.

2. Sticky Desktop Sidebar (300x600 Half-Page)

On desktop viewports, a sticky sidebar ad unit that scrolls gracefully alongside long-form content achieves viewability scores exceeding 85%. Ensure the sticky container stops before overlapping the footer.

3. Mid-Content Break (Paragraph 5 to 7)

For articles longer than 1,200 words, placing a responsive horizontal banner midway through the content captures natural reading pauses without frustrating the audience.
