SEO automation for internal linking at scale?
We have 800 blog posts. No internal links between them. Doing it manually would take months. Screaming Frog gives me the data but not the implementation.
I need something that reads each post, finds topically related posts, and inserts natural anchor text links, then updates the CMS. Worried about looking spammy to Google though. Has anyone automated internal linking without getting penalized? What guardrails did you use?
