Cross-Site Linker
Adds cross-reference links between two sister sites when the content naturally pairs — e.g. a procurement post linking to a matching vendor category.
Entry verified April 21, 2026
The short answer
Portfolio sites leave half their traffic on the table when posts on Site A never link to matching content on Site B. This skill scans a post (or all recent posts) on one site, finds the closest matches on its sister site by keyword + title, and proposes inline link insertions.
When to use it
After publishing a new post on either site in a paired portfolio (e.g. Tenderwatch + Vendors.ie). Also on a monthly sweep to catch missed links.
Setup
- 1
Define the paired-site map in ~/.claude/sites.json (site A → site B repo paths).
- 2
Save the skill as ~/.claude/commands/cross-link.md. Argument: source-post-slug (or “all” for recent).
- 3
Skill reads the source post, grep-scans sister-site content for keyword matches, proposes 1–3 link insertions with rationale.
Example
You: /cross-link accounting-software-ireland
Claude: Source: vendors.ie/accounting-software-ireland
Matches on tenderwatch.ie:
1. /sector/finance — high confidence (same SME buyer intent)
2. /authority/revenue-commissioners — medium (tangential)
Proposed: insert link to /sector/finance in “why Irish SMEs compare accounting tools” paragraph.Source & attribution

Caveats
Proposes links — doesn’t write them. Over-linking kills reader flow, so cap at 2–3 cross-site links per post.
