FAQ

Frequently asked questions

What is topic coverage?

Topic coverage refers to how comprehensively your content addresses all the subtopics and entities related to a keyword. High coverage signals high authority to search engines.

How do you find missing topics locally?

We use high-confidence topical blueprints for 100+ major niches to identify the 'table stakes' subtopics that search engines expect to see in a comprehensive guide.

Is my content private?

Yes. Your content is analyzed entirely in your browser. Nothing is sent to our servers or stored permanently.

Why does semantic depth matter for SEO?

Google's algorithms are now entity-based. By covering related concepts and 'semantic neighbors', you provide a stronger signal of expertise and relevance.

What are 'Entity Gaps'?

These are specific concepts (people, places, things, or technical terms) that top-ranking pages mention but your content currently lacks.

How long should my content be for good coverage?

Depth is more important than length. However, most high-coverage pages for competitive terms are between 1,200 and 2,500 words.

Does this tool work for any niche?

Yes, our auditor works across all major industries including SaaS, E-commerce, Health, Finance, and B2B services.

Should I include all missing topics?

Focus on the most relevant ones first. Not every subtopic is necessary for every article, but covering the core ones is vital for ranking.

How does this compare to expensive SEO tools?

Our tool provides instant, local analysis of topical depth without the need for expensive subscriptions, using proven search intent patterns.

Can I use this for landing pages?

Absolutely. Ensuring your landing page covers the key questions and subtopics your audience has is crucial for both SEO and conversion.

How do I fix low coverage scores?

Identify the subtopics marked as 'MISSING' and add dedicated sections (H2 or H3) addressing those points in your content.

Is there a limit to how much text I can audit?

The local browser tool handles articles up to ~10,000 words efficiently. For larger documents, we recommend auditing section by section.
