  GrandMaster SEO is your YouTube SEO co-pilot built for creators who are serious about growth. Stop guessing and start publishing with confidence.
  
  Open any video in YouTube Studio, click the GrandMaster SEO button, and get an instant 100-point score across every element that affects your reach — with specific fixes for every issue.
  
  FEATURES:
  
  📊 VIDEO SCORE (100 pts)
  Scores your title, description, tags, playlist assignment, and upload time. Each category shows exactly what's weak and how to fix it — not just a number.
  
  🖼️ THUMBNAIL ANALYZER
  Preview your thumbnail and get a full CTR analysis. Includes the 5-point thumbnail formula used by top YouTube creators.
  
  ✨ AI TITLE A/B GENERATOR
  Generates 2 click-optimized title variants for split testing — one curiosity-driven, one bold and direct. One-click copy to clipboard.
  
  📝 AI DESCRIPTION WRITER
  Writes a full SEO-optimized description with a strong hook, timestamps section, social links, and hashtags. Paste-ready in seconds.
  
  HOW IT WORKS:
  1. Go to YouTube Studio and open any video to edit
  2. Click the floating GrandMaster SEO button (bottom-right of the page)
  3. Fix the flagged issues, hit Rescan, and publish when you hit 80+
  
  BUILT FOR:
  - YouTubers tired of paying $19/month for tools that do the same thing
  - Creators who want to move fast and publish optimized content daily
  - MMA, sports, gaming, and commentary channels that upload frequently
  
  AI features require a free Anthropic API key (console.anthropic.com). Your key is stored locally on your device only — never shared.
  
  Built by Apex 74 Media.
