BuzzSumo
BuzzSumo tracks which content performs best across the web — searchable by topic or domain, ranked by social shares, backlinks, and engagement across Facebook, Twitter/X, YouTube, and TikTok. It also finds influencers, tracks competitor content, and analyzes questions people ask on Reddit, Quora, and Amazon.
BuzzSumo's own site claims an index of 8 billion-plus articles built from continuous content and social-engagement tracking going back up to 5 years — a standing historical archive that can't be reconstructed after the fact by a new tool querying today's APIs.
What you lose building it yourself
- ✕Years of historical share/engagement trend data that can't be recreated retroactively
- ✕One search across Facebook, Twitter/X, Reddit, YouTube, and TikTok engagement instead of stitching several APIs
- ✕Built-in journalist/influencer profiles and PR outreach tooling layered on the same index
BUILD YOUR OWN · NOT OFFERED
Matching BuzzSumo means continuously collecting and storing content and social-engagement data across several platforms for years, not querying an API once today — there's no way to backfill years of history you didn't collect as it happened. Entries with a real DIY path get a stack and a prompt here instead; this one doesn't have one.
QUESTIONS
Does BuzzSumo build its own crawler, or license data from social platforms?
BuzzSumo doesn't publish the technical mechanics — its own site states an 8bn+ article index with up to 5 years of history, but doesn't spell out crawler versus licensed-API sourcing anywhere public.
Is there a free way to get similar content and share data?
No close free or open-source equivalent exists for a multi-year, cross-platform engagement archive; a tool like Google Trends covers search-interest trends but not historical social share counts or a searchable content index.
Who owns BuzzSumo today?
Cision, a media-intelligence company — BuzzSumo was acquired by Brandwatch in 2017, then folded into Cision in 2021.
