What is BuzzSumo?
BuzzSumo is a content research and marketing platform that helps marketers discover what content performs best, identify trending topics, find influential people, and understand what resonates in any niche. Creating content that succeeds requires knowing what already works — which topics get shared, what formats perform, and who the influential voices are — rather than guessing. BuzzSumo provides this intelligence by analyzing how content performs across the web and social media, giving marketers data-driven insight to inform their content strategy and avoid creating things nobody wants.
The platform lets you search any topic or competitor and see the content that has performed best by engagement and shares, revealing what resonates with audiences. It surfaces trending and emerging topics so you can ride interest while it's hot, helps you find influencers and journalists relevant to your niche for outreach and partnerships, and lets you monitor mentions and track competitors' content. By grounding content decisions in real performance data — what's actually being shared and discussed — BuzzSumo helps marketers create content with a far better chance of success and find the people and topics worth engaging.
BuzzSumo is used by content marketers, PR professionals, and SEO teams who want to create content that performs and find the right topics, trends, and influencers. The value is data-driven content strategy: instead of guessing what to write, marketers see what actually works, spot trends early, and identify the influential voices to reach — dramatically improving the odds that their content and outreach succeed. Because creating content that no one engages with is a costly waste, the insight to create the right content is genuinely valuable. For content and PR teams that want to base their strategy on evidence rather than intuition, BuzzSumo offers a powerful, established research platform.
