    FAQ

    • What is keyword coverage?

      Keyword coverage is the share of your target keywords that actually appear in your content. High coverage means your piece addresses the topics you want to rank for; gaps show where to add or expand sections.

    • How many keywords should my article target?

      It depends on length and intent. A short post might focus on 3–5 primary terms; a long guide can naturally cover 15–25. Prioritize a few primary keywords and treat the rest as secondary. Overstuffing hurts readability and rankings.

    • What's the difference between exact and semantic keyword matches?

      An exact match means the full phrase appears in the text (e.g. "B2B SaaS SEO"). A semantic match means all words in the keyword appear in the same sentence but not necessarily as one phrase. Both count toward coverage; exact matches are stronger signals.

    • How does this tool work?

      You paste your article and upload or paste a keyword list. The tool strips formatting, normalizes the text, and checks which keywords appear exactly and which appear only as semantic matches (same sentence). It then scores coverage and highlights gaps and overstuffed terms. All processing runs in your browser; nothing is stored or sent.
