| after-heading | After first H2 | Early engagement |

| before-conclusion | Before last paragraph | Strong finish |

CTA Templates

Templates are HTML files in the templates/ directory:

<!-- templates/newsletter.html -->
<aside class="cta-newsletter" data-cta-type="newsletter">
  <h3>{{title}}</h3>
  <p>{{description}}</p>
  <form action="{{form_url}}" method="post">
    <input type="email" placeholder="Your email" required />
    <button type="submit">Subscribe</button>
  </form>
</aside>

Variables:

• {{title}} - CTA headline
• {{description}} - CTA body text
• {{form_url}} - Form submission URL
• {{product_url}} - Product link
• {{image_url}} - Image source

Workflow

Step 1: Score Posts for Relevance

python scripts/score_posts.py --content-path ./src/content/blog --cta-type newsletter

Step 2: Preview Injections

python scripts/preview_injection.py --input scored_posts.json --cta-type newsletter

Step 3: Apply Injections

python scripts/inject_ctas.py --input scored_posts.json --cta-type newsletter

Input Format

Scored posts JSON:

{
  "posts": [
    {
      "file_path": "./src/content/blog/my-post.astro",
      "title": "My Blog Post",
      "relevance_score": 8.5,
      "cta_type": "newsletter",
      "placement": "after-paragraph-50%",
      "cta_data": {
        "title": "Get More Tips Like This",
        "description": "Subscribe to my weekly newsletter"
      }
    }
  ]
}

Scoring Algorithm

Posts are scored for CTA relevance based on:

• Keyword density - How many relevant keywords appear
• Content length - Longer posts = better candidates
• Topic match - Title and content topic alignment
• Existing CTAs - Skip posts that already have CTAs

Scores range from 0-10. Default threshold: 5.0

Safety Features

• Dry-run mode by default
• Backup creation before any modifications
• Duplicate detection - Won't inject if CTA already exists
• Rollback capability - Restore from backups
• Preview diffs - See exactly what will change

Example Usage

User: "Add a newsletter signup CTA to all my productivity-related blog posts"

Claude will:

• Scan content directory for posts
• Score posts for "newsletter" relevance using productivity keywords
• Generate CTA HTML from template
• Show preview of changes
• Ask for confirmation
• Inject CTAs into matching posts
• Report results
