Google AdSense is a free program that allows website owners and content creators to display ads from Google’s vast advertising network on their platforms. Advertisers pay Google to place ads, and Google shares a portion of this revenue with publishers based on ad clicks or impressions.

Before applying, ensure your website meets the following updated requirements:

Original Content: Your site must have sufficient unique and original content (generally 20+ quality pages).
Website Age: Many regions require your website to be at least 6 months old.
Navigation & User Experience: Easy-to-navigate design and responsive layout for mobile and desktop.
Compliance: Adhere to Google’s content policies—no adult content, copyrighted materials without permission, or prohibited content.
Privacy Policy & Legal Pages: Include Privacy Policy, About Us, and Contact pages.
Ownership Verification: You must own and control the website you apply with.
Age Limit: You must be 18 years or older to participate.

Approval times vary, but typically you can expect:

Initial Application Review: 1 to 3 days, ensuring your site complies with basic policies.
Site Verification and Content Review: 1 to 2 weeks, where Google checks content volume and quality.
Final Approval or Rejection: Usually within 2 to 4 weeks in total.

If your application is rejected, Google provides reasons and you may reapply once issues are resolved. Maintaining quality and compliance shortens approval duration.

Step 3: What Is Ads.txt and Why Is It Important in 2025?

What is Ads.txt?

Ads.txt (Authorized Digital Sellers) is a text file published on your website that declares authorized sellers of your digital ad inventory. Created by the Interactive Advertising Bureau (IAB), it aims to prevent ad fraud and unauthorized reselling.

Why Does Google AdSense Require Ads.txt?

Starting from 2024, Google began enforcing Ads.txt compliance rigorously. Publishers without a correctly configured Ads.txt file risk losing ad demand and reduced monetization.

How to Set Up Ads.txt for Your Website

Create a plain text file named ads.txt.
Add the authorized sellers line for Google AdSense. Example:
google.com, pub-XXXXXXXXXXXXXXXX, DIRECT, f08c47fec0942fa0
Upload the file to your website’s root domain directory.
Use Google AdSense’s Ads.txt Analyzer to verify your setup.

Benefits of Implementing Ads.txt

Protects your ad revenue from domain spoofing.
Enhances advertiser trust, potentially increasing CPM.
Ensures compliance with Google’s global policies.

Regularly publish original, high-quality content.
Ensure your website design is professional and user-friendly.
Maintain consistent traffic and avoid sudden spikes from suspicious sources.
Complete all required legal and policy pages.
Properly configure your Ads.txt file promptly.
Use Google’s Search Console to fix indexing and crawling issues.
Avoid invalid traffic and click fraud at all costs.

Once approved:

Use Auto Ads for AI-driven placement and optimization.
Monitor your AdSense Dashboard daily for earnings, CTR, and RPM.
Experiment with different ad formats: display, native, in-feed, matched content.
Stay updated on new features and policy changes via official Google communications.
Protect your account by using two-factor authentication.

Common Mistakes to Avoid Regarding Approval and Ads.txt

Ignoring Ads.txt setup leads to loss of demand.
Submitting applications with thin or copied content.
Having broken or missing legal pages.
Using invalid traffic sources risking account suspension.
Waiting too long to fix application rejection issues.

Can I apply for AdSense before my website is 6 months old?
Google in many countries requires a minimum website age, but this can vary. It’s best to check current criteria in the AdSense Help Center.

How can I check if my Ads.txt is setup correctly?
Use Google’s free Ads.txt analyzer tool available in your AdSense dashboard or third-party vendors.

What happens if I don’t set up Ads.txt?
You may see a drop in ad demand and revenue as advertisers avoid uncertified inventory.
