Discovery
How well the tool identifies, qualifies, clusters, and prioritizes keywords specifically for SEO content creation.
BuzzStream
No native keyword-research capability is claimed on the official product pages.
The official feature tour describes prospect lists, web/news searches, contacts, and website metrics, not keyword research: https://www.buzzstream.com/outreach/research/

Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
BuzzStream
The site gives only a qualitative adoption claim, not a numeric customer count.
The homepage says 'Thousands of the world's best Marketers Use BuzzStream Every Day,' without a precise customer number: https://www.buzzstream.com/
