Internal linking is architecture, not decoration. The goal is to help users discover the next useful resource, clarify hierarchy for search engines, and route relevant informational traffic toward commercial pages where appropriate.
What to automate
Candidate discovery, semantic matching, orphan detection, and repetitive insertion can be automated effectively when the system understands your site.
What to review
Anchor wording, destination usefulness, link density, monetization pressure, and whether the relationship is genuinely meaningful should still be reviewed.
Koala's approach
Koala currently offers automatic internal linking in KoalaWriter and a KoalaLinks product that analyzes site content to generate contextual links. Koala states that the Professional tier and above include automatic internal linking.
