BuzzSumo approaches keyword and topic research from a content marketing angle rather than a pure SEO one. Its core strength is showing you which pieces of content on any given topic have earned the most shares, backlinks, and engagement across social platforms. Enter a keyword or topic and BuzzSumo surfaces the most popular articles, videos, and infographics associated with it, along with their share counts across Facebook, Twitter, Pinterest, Reddit, and more. This tells you something that traditional keyword tools don’t: what format and angle resonates most with the audience around your topic.
For content strategists, the practical value is in understanding the gap between what gets searched and what actually gets shared. A keyword might have strong search volume but produce a lot of undifferentiated, low-engagement content, meaning there’s an opportunity to create something genuinely more useful and shareable. The trending topics feature and the content alerts function, which notifies you when new content on your tracked topics goes viral, are genuinely useful for staying on top of what’s resonating in your niche.
BuzzSumo isn’t a keyword research tool in the traditional sense. It doesn’t give you search volumes, keyword difficulty scores, or SERP analysis. You’ll need a companion tool like Semrush or Ahrefs for that. At $99 per month, it’s also at the pricier end for a specialised tool. But if your work sits at the intersection of SEO and content marketing, and you need to understand which topics and angles drive real audience engagement rather than just search traffic, BuzzSumo is a genuinely distinctive and valuable research platform.
