To address the "low content quality" issue and improve your chances of AdSense approval, focus on creating high-quality, in-depth content that offers unique insights and value to your audience. Analyze your existing content, expand on existing articles, and publish fresh, engaging content that targets relevant keywords. Optimize your website's user experience, encourage user engagement, and adhere to Google's Webmaster Guidelines. While waiting for Google to re-evaluate your site, consider exploring alternative monetization options like affiliate marketing or sponsored content.
