Why should you switch from AdSense to Google Ad Manager?

Google AdSense is a great starting point for monetizing a website, but as your traffic and goals grow, it may no longer be enough. That is where Google Ad Manager (GAM) steps in. It offers far more control, flexibility, and monetization potential for serious publishers. With access to multiple demand sources, advanced targeting, and dynamic revenue optimization tools, switching to GAM can help you scale faster and earn more. In this post, we will dive into the main reasons why upgrading from AdSense to Google Ad Manager is a smart move for ambitious publishers.

Limitations of AdSense for Growing Publishers

Understand the constraints of AdSense in terms of earnings potential, control, and scalability.

• Limited Demand Sources:

• Only serves ads from Google’s network, preventing you from tapping into direct deals or third party programmatic partners.
  

• Minimal Inventory Control:

• You cannot prioritize campaigns, set custom price floors, or segment ad units—Google decides what to show and when.
  

• Basic Targeting Options:

• Lacks granular audience or content targeting; ads are matched primarily by page context and general visitor data.
  

• Simplified Reporting:

• Provides only high level metrics (e.g., impressions, clicks, RPM) with no insight into performance by advertiser, line item, or placement.
  

• No Header Bidding Support:

• You can not integrate header bidding partners to increase competition and CPMs before Google’s auction.
  

• Rigid Ad Formats & Placements:

• Only standard display and in page ads; no native, custom, or advanced video placement options that could command higher rates.
  

• Policy Constraints:

• Strict content and layout rules often limit your ability to experiment with ad load or placement density.
  

• Scalability Ceiling:

• As traffic and revenue grow, AdSense’s auto managed approach can lead to diminishing returns compared to a fully controlled platform.

• Access to Multiple Demand Sources:

• Advanced Inventory Management:

• Create and organize ad units, line items, and placements for precise control over where and how ads appear.
  

• Set price floors, delivery priorities, and custom targeting rules to optimize yield.
  

• Dynamic Allocation:

• Automatically compares all eligible demand (AdX, direct, third-party) and serves the highest-paying ad in real-time.
  

• Header Bidding Support (Open Bidding):

• Allow non-Google demand partners to compete for your inventory, increasing competition and revenue.
  

• Comprehensive Reporting & Analytics:

• Access detailed metrics like revenue by ad unit, geography, device, advertiser, and buyer.
  

• Use these insights to improve placement strategies and spot underperforming areas.
  

• Support for Premium Ad Formats:

• Serve native ads, video ads (including outstream), interstitials, and custom creatives to attract higher-paying advertisers.
  

• Audience Segmentation & Targeting:

• Use first-party data, custom key-values, and behavioral insights for better ad personalization and higher CPMs.

• GAM is built for growth—supporting complex setups across websites, mobile apps, and even connected TV platforms.
  

When Is the Right Time to Make the Switch?

Key signs your site has outgrown AdSense and is ready for the next level with GAM.

• Your Website Traffic Is Growing Rapidly

• If you are consistently receiving over 100,000 pageviews per month, you are likely leaving money on the table with AdSense.
  

• You Have Multiple Ad Revenue Sources

• If you want to manage direct deals, affiliate placements, or third-party ad networks alongside AdSense, GAM offers full integration.
  

• You Need More Control Over Ad Strategy

• Want to set custom price floors, delivery priorities, or control ad placements more granularly? That is a clear sign to move beyond AdSense.
  

• You Want Access to Premium Advertisers via Ad Exchange (AdX)

• AdX buyers often pay higher CPMs, but you can only access them through Google Ad Manager—not AdSense alone.
  

• You are Planning to Use Header Bidding or Open Bidding

• If you are ready to increase competition for your ad inventory, GAM lets you enable header bidding with Open Bidding support.
  

• Your Revenue Has Plateaued with AdSense

• If your AdSense earnings have stagnated despite traffic growth, it may be time for a more advanced and customizable platform.
  

• You Require Advanced Reporting & Optimization

• GAM provides in-depth reports, breakdowns by device, region, ad unit, buyer, and more—ideal for publishers who want to optimize intelligently.
  

• You Manage Multiple Sites or Platforms (Web + App + Video)

• GAM allows for centralized ad management across different properties, making it easier to scale a diversified publishing business.

How to Transition from AdSense to Google Ad Manager

Step-by-step tips on migrating to GAM smoothly, including setup, policies, and linking AdSense within GAM.

✅ 1. Check Eligibility and Apply for Google Ad Manager

• Make sure your website meets traffic, content, and policy standards for Google Ad Manager (especially for Ad Exchange access).

• Visit admanager.google.com and apply for a GAM account—approval may take a few days.

✅ 2. Familiarize Yourself with GAM Structure

• Understand the core elements:

• Ad Units (placements on your site)
  

• Orders & Line Items (ads/campaigns you run)
  

• Inventory Hierarchy and Trafficking rules
  

• This knowledge helps avoid misconfiguration and revenue loss.

✅ 3. Link Your AdSense Account to GAM (Optional but Recommended)

• Navigate to Admin > Linked Accounts in GAM and connect your existing AdSense account.

• This allows AdSense to compete with other demand sources through dynamic allocation.

✅ 4. Set Up Your Ad Inventory

• Create ad units for each placement on your website (e.g., header, sidebar, in-article).

• Define ad sizes, formats, and targeting rules.

✅ 5. Generate and Implement Ad Tags

• Use the Google Publisher Tag (GPT) system to create ad tags for each ad unit.

• Place the tags into your website's HTML or CMS (WordPress, Blogger, etc.) where you want ads to display.

✅ 6. Create Line Items and Orders

• Set up line items for different campaigns, including fallback options and pricing rules.

• You can also run house ads or direct campaigns alongside programmatic demand.

✅ 7. Test and Monitor Ad Delivery

• Use the Google Publisher Console (Ctrl + F10) to test and debug ad placements.

• Monitor ad performance and adjust targeting, pricing, or layout as needed.

✅ 8. Ensure Policy Compliance

• Review Google’s Publisher Policies for GAM and Ad Exchange to avoid violations.

• Avoid misleading content, invalid traffic, and excessive ad density.

✅ 9. Optimize and Scale

• Use advanced reporting tools to analyze performance by ad unit, format, region, and device.

• Gradually integrate header bidding partners or explore private marketplace deals for additional revenue.
