Content Gap Analysis

  1. List competitor URLs ranking for target keywords
  2. Identify keywords they rank for that you don't
  3. Prioritize by: search volume × (1 - your current position/10)
  4. Map each gap keyword to existing content (optimize) or new content (create)

  • Target keyword in: <title> (front-loaded), H1, first 100 words, one H2, URL
  • Meta description: 150-160 chars, includes target keyword, compelling CTA
  • Images: descriptive alt text, compressed (WebP preferred), lazy loaded
  • Internal links: 3-5 contextual links to related content
  • External links: 1-2 authoritative sources (opens in new tab)
  • Reading level: Hemingway Grade 8 or lower for general audience
  • Content length: matches or exceeds top 3 ranking competitors

Prioritized Action Plan Format

For each finding:

  • Issue description
  • Pages affected (count)
  • Estimated traffic impact (Low / Medium / High)
  • Implementation effort (Low / Medium / High)
  • Priority score = Impact / Effort

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.
