Discovery
How well the tool identifies, qualifies, clusters, and prioritizes keywords specifically for SEO content creation.

The official content-optimization page documents Google Search Console metrics and filters, not generative-engine visibility: https://keywordspeopleuse.com/content-optimization-tool

Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.
KeywordsPeopleUse

Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
KeywordsPeopleUse
Alerts, bulk search, daily syncing, AI templates and exports automate parts of research and optimization, but human review and publishing remain necessary.

Page Optimizer Pro
Guided scores and AI assistance reduce manual analysis, but users still choose pages, review advice, and implement changes.
