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

Execution
How well the tool helps produce, optimize, or operationalize SEO content.

Executes internal-link insertion, anchor suggestions and URL updates, but does not write or optimize full content.
One-click insertion, anchor text suggestions and the URL Changer are documented at https://linkwhisper.com/features/.
