Automated Internal Linking

Internal links matter for SEO. Automating them is high-leverage:

Finding link opportunities:

1. Schedule: weekly
2. Database: pull all published articles (title, slug, target keywords)
3. New article published → trigger
4. Claude: "Given this new article about [topic], which existing articles should link to it? Suggest the anchor text and where in each article a link would fit naturally."
5. Slack: notify content team with link recommendations
6. (Optional) WordPress API: auto-insert links where confidence is high

Core Web Vitals monitoring:
