Evaluate Page Heading Structure
Audit H1-H6 heading hierarchy to ensure proper content structure for SEO and accessibility.
Analyze Keyword Density on a Page
Measure keyword usage and density to ensure your content is properly optimized without over-stuffing.
ToolKeyword density matters — but not in the way many people think. The goal isn't hitting a specific percentage; it's ensuring your target keywords appear naturally in the right places (title, H1, first paragraph, headings) while the overall content reads well and covers the topic thoroughly.
ToolRouter's extract_keywords and analyze_content skills work together to show exactly which keywords appear on your page, how often, and in what context. This reveals whether you're under-optimizing (keywords barely mentioned) or over-optimizing (keyword stuffing that triggers Google penalties).
This analysis is most valuable during content creation and editing. Running it on draft content before publishing lets you adjust keyword usage while the content is still flexible.
