I don't have real-time data, and as of my last knowledge update in January 2022, I cannot provide you with the current hot search keywords for AdSense. However, I can give you some general tips on finding relevant keywords:

1. Google Trends: Visit Google Trends (trends.google.com) to explore the latest search trends. You can filter by location and category to find popular topics.

2. Keyword Research Tools: Utilize keyword research tools like Google Keyword Planner, SEMrush, or Ahrefs. These tools can provide insights into search volume, competition, and related keywords.

3. Industry News and Updates: Stay informed about trends and news in your industry or niche. This can help you identify keywords related to current events or popular topics.

4. Social Media Trends: Monitor social media platforms for trending topics and discussions. Twitter, in particular, is known for real-time updates on popular subjects.

5. AdSense Keyword Planner: If you're using Google AdSense, you can explore the AdSense Keyword Planner for insights into relevant keywords and topics.

Remember that the effectiveness of keywords can vary based on your niche and target audience. It's crucial to choose keywords that align with your content and are likely to attract your desired audience. Additionally, keep in mind that the popularity of keywords can change rapidly, so regularly revisiting your keyword strategy is essential for staying relevant.
