Clearbit
Data EnrichmentB2B data enrichment for audience understanding and personalization
Overview
Clearbit transforms anonymous website visitors into actionable business intelligence, making it particularly valuable for understanding who finds your content through organic search. Founded in 2014, the San Francisco-based company has built one of the most comprehensive B2B data platforms, processing over 1 billion API calls monthly for companies ranging from startups to Fortune 500 enterprises.
While not technically an SEO tool, Clearbit solves a critical problem for content marketers and SEO practitioners: understanding who your organic search traffic actually represents. Most SEO tools tell you about keywords and rankings, but Clearbit reveals the companies, job titles, and business characteristics of people finding your content through search. This intelligence enables more targeted content strategies and better measurement of SEO's business impact.
The platform's strength lies in its real-time enrichment capabilities and extensive database of over 100 million B2B profiles. Unlike audience research tools that rely on surveys or sample data, Clearbit provides actual firmographic and demographic data about your website visitors, making it easier to optimize content for high-value prospects rather than vanity metrics.
