Some General Reasons why Adsense might not approve or rejected website for monetization. 

It's really necessary to know about AdSense website requirements for monitization.

1. Insufficient content

If your website has insufficient content and lacks high-quality content, there is a high probability that AdSense will reject your website.

2. Poor website design and navigation

A website with poor user experience i.e. user dissatisfaction, confusing layout, or difficult navigation can also be rejected by AdSense.

3. Copyright or intellectual property issues

 If your website contains copyrighted material without permission, copyrighted material mean you have used content which is uploaded or published on another website or platform. Adsense may not approve it.

4. Adult or explicit content

Adsense has strict policies against adult content, so if your website contains such material, it will likely be rejected.

5. Excessive advertising

If your website already has an overwhelming number of ads, Adsense might not approve it.

6. Low traffic

 Adsense typically requires a minimum amount of traffic before approving a website for monetization.

7. Non-compliance with Adsense policies

 Ensure your website adheres to Adsense's program policies, guidelines, and terms.

8. Website age

 Adsense may require your website to be active for a certain period (usually 6 months) before approving it.

9. Quality of content

 Adsense favors websites with high-quality, engaging, and informative content.

10. Technical issues

 Ensure your website is mobile-friendly, has a secure protocol (HTTPS), and is free of malware and other technical issues.

Remember;

Review your website and Adsense account to identify any potential issues. Make necessary adjustments and reapply for Adsense monetization. If you need more specific guidance, consider reaching out to Adsense support directly.
