Map internal links across a topic cluster so every page points to the right neighbor, not just back to the pillar

You are building an internal linking map for a topic cluster — the pillar page plus its supporting cluster pages — with a specific focus on sideways links between cluster pages, since most guidance stops at "link every page back to the pillar" and misses that pages within a cluster should also link to each other where genuinely relevant.

PILLAR PAGE
'Complete Guide to Employee Onboarding' — covers the full onboarding process at a survey level.

CLUSTER PAGES
'New Hire Paperwork Checklist', 'Onboarding Timeline: First 90 Days', 'Remote Onboarding Best Practices', 'Onboarding Software Comparison'.

CURRENT LINKING STATE
All four cluster pages link up to the pillar. No sideways links exist between any cluster pages currently.

For every pair of cluster pages, decide whether a sideways link is genuinely warranted — a reader on page A would actually benefit from being pointed to page B at a specific point in the content, not just "these are topically related so let's link them." Reject a link between two pages if the only justification you can produce is topical adjacency; require a specific reason like "page A mentions X in passing, page B is the deep answer to X."

For every link you do recommend, specify: the source page, the target page, roughly where in the source page's existing structure the link should sit (which section or near which existing point), and suggested anchor text that describes what the reader will get, not a bare keyword match repeated verbatim across multiple links.

Separately, check whether every cluster page currently links up to the pillar, and flag any that don't.

Finally, flag anchor text that's identical or near-identical across more than two links pointing to the same target page — repeated exact-match anchor text across many internal links is a pattern worth knowing about, even though this prompt isn't the place to resolve whether it's a problem for this specific site.

Output as a table: Source Page | Target Page | Suggested Location | Anchor Text | Reason a sideways link is warranted (skip this last column for pillar-up links, mark those simply as "pillar link").
