In this comprehensive comparison, I will break down both methods based on real-world testing and data to help you make the best choice for your website.
What You Will Learn:
- How Auto Ads and manual placement work
- Revenue differences between methods
- User experience considerations
- Best practices for each approach

How Auto Ads Work
Auto Ads use Google's machine learning to analyze your pages and automatically place ads in locations predicted to perform well. According to Google's Auto Ads documentation, the AI continuously learns from performance data.
The Technology Behind Auto Ads
Google's AI considers:
- Page layout and structure
- Content length and format
- User behavior patterns
- Device type (mobile vs desktop)
- Historical performance data
Auto Ad Types
Auto Ads can display:
- In-page ads: Within content areas
- Anchor ads: Sticky ads at screen edge
- Vignette ads: Full-screen ads between pages
- Side rail ads: On widescreen displays
- Multiplex ads: Grid-style native ads
How Manual Placement Works
Manual placement gives you complete control over where ads appear on your site.

- Strategic manual placements capture high-value impressions
- Auto Ads find additional opportunities
- Google's AI adapts to your manual placements

Frequently Asked Questions
Can I use Auto Ads and manual ads together?
Yes. AdSense is designed to work with both. Auto Ads will not place ads where you already have manual units, so you get additional placements rather than duplicates.
Will Auto Ads hurt my SEO?
They can impact Core Web Vitals if too many ads load. Monitor your metrics in Search Console and adjust the ad load slider if needed.
How many manual ads should I place per page?
There is no strict limit, but 3-5 ads per page is typical. Focus on quality placements rather than quantity. Google's policies prohibit more ad content than actual content.
Do Auto Ads work on all pages?
Auto Ads analyze each page and may not place ads on pages where they predict poor performance, such as very short pages or checkout flows.
How long to test before deciding?
Test each approach for at least 2-4 weeks to gather enough data. Seasonal variations can affect short-term results.
