BuzzSumo
Content ResearchContent research platform tracking viral trends and social engagement
Overview
BuzzSumo pioneered content research by making social engagement data actionable for marketers and content creators. Founded in 2013 by James Blackwell and Henley Wing, the Brighton-based company built its reputation on answering a simple question: what content actually gets shared? Unlike tools that focus on search volume or rankings, BuzzSumo reveals which topics generate discussion, shares, and viral momentum across social platforms.
The platform's core strength lies in its comprehensive social media database, tracking billions of content pieces across Facebook, Twitter, LinkedIn, Pinterest, and Reddit. This gives content creators visibility into real engagement patterns rather than theoretical keyword metrics. BuzzSumo competes directly with tools like SparkToro for audience research and Exploding Topics for trend identification, but its social-first approach sets it apart from traditional SEO tools.
BuzzSumo serves multiple use cases beyond basic content discovery. PR teams use it to identify journalists and monitor media coverage. Influencer marketers use its creator database for outreach campaigns. Content strategists analyze competitor content gaps and track trending discussions in their industry. The platform has evolved from a simple content discovery tool into a comprehensive social intelligence platform.

FAQ
How does BuzzSumo compare to Google Trends for content research?
BuzzSumo focuses on social engagement data while Google Trends shows search volume trends. BuzzSumo is better for understanding what content gets shared and discussed, while Google Trends shows what people search for.
Can BuzzSumo help with SEO keyword research?
BuzzSumo doesn't provide search volume data or keyword metrics. It's primarily for identifying content topics that generate social engagement, which can inform content strategy but doesn't replace dedicated keyword research tools.

The free version allows 5 searches monthly with basic results. It's enough to test the platform but insufficient for regular content research. Most users need a paid plan for consistent use.
Does BuzzSumo track all social media platforms?

Testimonials
“I can search for terms/phrases and quickly identify content that's performing well in a niche or with an audience.”
“Whatever technology you have fuelling the engine of BuzzSumo seems to be better than most others. It can pick up new links a lot quicker than other link index tools or manual searches. For us, that's absolutely crucial.”
“I fell in love with BuzzSumo. It was the missing link I'd been looking for. I use it religiously, every single day. The result we're aiming for is top tier press coverage – not just UK, but global coverage – across some of the largest publications in the world, and BuzzSumo is absolutely pivotal to us achieving that. Without BuzzSumo, we would struggle.”
