Implementation Strategy

Phase 1: Meta Description Generation

Process:

  1. Read all 558 markdown files
  2. Extract title and content (first 1000 chars)
  3. Generate unique description via Gemini API
  4. Validate length (120-160 chars)
  5. Update front matter
  6. Save checkpoint every 10 posts

Quality Criteria:

Prompt Engineering:

Generate a compelling SEO meta description (140-155 characters) for this article.

Title: [Post Title]
Article excerpt: [First 1000 characters]

Requirements:
- 140-155 characters (STRICT)
- Action-oriented (Discover, Learn, Fix, Guide)
- Focus on main benefit
- Professional tech blog tone
- NO quotes, special chars, emojis
- Complete sentence
- Specific to this article

Return ONLY the meta description text.

Validation:

// Length check
if (description.length < 120 || description.length > 160) {
  retry();
}

// Quality check
description = description
  .replace(/^["']|["']$/g, '')  // Remove quotes
  .replace(/\s+/g, ' ')         // Normalize whitespace
  .trim();

// Trim if too long (keep sentences)
if (description.length > 160) {
  description = trimToSentence(description, 160);
}

Phase 2: URL Consolidation

Problem: Multiple URL patterns per post cause duplicates:

Solution:

  1. Standardize to: /posts/META-DESCRIPTION-FIX-PLAN/
  2. 301 redirects for old URLs
  3. Update permalink configuration

Implementation:

posts/posts.json:

{
  "layout": "layout.njk",
  "tags": "post",
  "permalink": "/posts/META-DESCRIPTION-FIX-PLAN/"
}

_redirects (Cloudflare format):

/2025/:month/:day/*  /posts/2025-:month-:day-:splat 301
/2024/:month/:day/*  /posts/2024-:month-:day-:splat 301
/2023/:month/:day/*  /posts/2023-:month-:day-:splat 301
/2022/:month/:day/*  /posts/2022-:month-:day-:splat 301
/2021/:month/:day/*  /posts/2021-:month-:day-:splat 301
/priority-meta-backups/*  /posts/:splat 301

.eleventy.js:

eleventyConfig.addPassthroughCopy("_redirects");

Phase 3: Validation & Testing

Pre-Generation Validation:

node validate-meta-descriptions.js
# Shows: 858 issues (300 default + 558 duplicates)

Post-Generation Validation:

node validate-meta-descriptions.js
# Shows: 0 issues (all unique, proper length)

URL Validation:

node check-url-duplicates.js
# Shows: URL pattern issues (before fix)
# Shows: All consistent (after fix)
