What Is Google AdSense and How Does It Work?

📌Google AdSense is an advertising program by Google that allows website owners and content publishers to earn money by displaying ads on their websites. These ads are created and paid for by advertisers through Google Ads, and AdSense serves them automatically based on your site content and visitors.

In short, Google acts as a bridge between advertisers and publishers. As a publisher, you get paid when users view or click on the ads displayed on your site.

Launched in 2003, AdSense has become one of the most reliable monetization tools for:

  • Blogs
  • News portals
  • Forums
  • Educational websites
  • Niche content platforms

⚙️ How Does Google AdSense Work?

At its core, Google AdSense functions through a revenue-sharing model. Advertisers bid to show ads on relevant content, and you, the publisher, earn a percentage of that revenue.

🔑 Here’s a step-by-step overview:

1. Sign-Up & Approval

You sign up for AdSense, submit your website, and Google reviews your site to ensure it complies with their policies.

2. Ad Code Integration

Once approved, you get an ad code snippet to place on your website where you want the ads to appear.

3. Ad Matching

Google scans your site’s content and visitors’ behavior, then serves relevant ads using algorithms and real-time bidding.

4. User Interaction

When visitors view (impression-based revenue) or click (click-based revenue) on these ads, you earn a share of the revenue.

5. Payout

Once your earnings reach the minimum threshold ($100), Google sends you the payment, typically via bank transfer or check.

📊 How Is Revenue Calculated?

AdSense revenue is influenced by:

CTR (Click Through Rate)% of users who clicked the ad
Page RPM (Revenue per 1,000 Impressions)Estimated earnings per 1,000 views
