# Blog Content Extraction and Linking - Complete

**Last Updated:** 2026-01-10

## Summary

All blog content has been re-extracted with fixed extraction logic, updated in post JSON files, and internal links have been re-added using the corrected word boundary logic.

## Process Completed

### 1. Content Extraction ✅

Re-extracted all blog posts using the fixed extraction script:
- Removed CTAs (5 detection patterns)
- Removed author names (3 detection patterns)
- Removed container/border divs (preserved content divs)
- Preserved all embeds (iframes, scripts, videos)

**Results:**
- Posts extracted: 99
- Successful: 99
- Failed: 0

### 2. Post JSON Updates ✅

Updated all individual post JSON files with cleaned content:
- Preserved existing metadata (internal_links, related_posts, etc.)
- Updated content.html with cleaned HTML
- Updated content.text and content.word_count

### 3. Link Re-addition ✅

Re-added internal links using corrected logic:
- Uses `findFullWordByContext()` to find actual words
- Links full words without changing content
- Preserves content integrity (no word splitting)

## Verification

Sample post check (`product-updates-q4-2024`):
- ✅ Content HTML length: ~11,245 characters
- ✅ CTAs removed: No CTA text found
- ✅ Author removed: No author text found
- ✅ Containers removed: No wrapper containers (content divs preserved)
- ✅ Embeds preserved: Iframes found
- ✅ Links added: Internal links present
