SEO.AI
Some support for using customer/business data and expertise is stated, but the public pages do not document a rich context-ingestion system.

AI-search / GEO
Visibility
How directly the tool helps teams improve visibility in AI answer engines and citation-oriented search journeys.

The official AI-bot page describes bot activity, status codes, response times and crawl health, but does not present a full technical SEO audit: https://keyword-hero.com/log-hero
SEO.AI
Only weak/indirect evidence for technical SEO; the public product pages focus on content, publishing, and links rather than crawls or technical remediation.

SEO.AI
Approval/review modes, human support, and agency suitability help collaboration, but roles, permissions, and workflow collaboration are not documented.

First-party adoption claim exists
The homepage states “Powering 24,000+ companies”: https://keyword-hero.com/
SEO.AI
No numeric customer-count estimate is published in the fetched official product material.
The official FAQ says many customers are agencies, but gives no count; therefore no scale credit is assigned. https://seo.ai/support-page
