How to Find Trending Topics Online for Content, Social Media and SEO (Free Tools and a Weekly Workflow)
How to find trending topics and keywords online
In this article
To find trending topics online, combine search trend tools (Google Trends, keyword tools like Semrush and Ahrefs, Exploding Topics), platform trend signals (YouTube and TikTok trending pages, TikTok Creative Center, Instagram Reels audio, X and Reddit), and news and industry sources. Then filter trends for relevance to your audience and act quickly with content: short videos, posts or articles. A weekly routine (and simple automation) makes trend-spotting consistent.
