PI Definitions Cluster — Index, Internal-Link Map, and Publishing Schedule

Category: Insurance definitions · Reviewed by Al Jabbar, Broker · Specialist Risks · Last reviewed May 2026

This file is internal. It catalogues the 30 ultra-long-tail definition articles drafted for the /learn/ or /glossary/<slug>/ URL tree, with target query, search-intent classification, the principal internal links each article should receive, and a paced publishing schedule (two per week for 15 weeks) designed to avoid duplicate-content / thin-content perception during indexing.

All 30 articles are stored as siblings of this file in article-drafts/definitions/.

How the cluster fits the wider site

These articles go deeper on a single term than the consolidated glossary page does. The glossary remains the hub; each of these is a spoke. To prevent self-cannibalisation:

Volume bands are estimates based on UK Search Console patterns for similar long-tail B2B insurance queries; they should be checked in Ahrefs / Semrush before publication.

Search-intent classification (consolidated)

Commercial-investigation and decision-stage pages should carry the heaviest internal-link weight from sector pages, the pillar guides, and the contact CTA, because they sit closest to a quote enquiry.

Internal-link recommendations

Each article must link out to:

  1. /glossary/ — anchor: “PI insurance glossary”
  2. Relevant pillar guide (default: /the-ultimate-uk-professional-indemnity-insurance-guide-2026/)
  3. Three to five sibling definition articles in this set (via the “Related definitions” block)
  4. At least one sector page where the term is most material
  5. /contact/ — for users at decision stage

Tight internal-link clusters (group together)

Suggested publishing schedule (2 per week × 15 weeks)

Schedule paces publication so Google indexes the cluster gradually, avoids two near-identical queries hitting the index in the same crawl window, and front-loads the highest-volume / commercial-intent terms.

Week Article A Article B Rationale for pairing
1 5. claims-made-vs-occurrence-pi-explained 30. pi-insurance-utmost-good-faith-explained Two foundational, high-volume informational pages establish the cluster’s authority. Topics don’t overlap.
2 1. aggregate-limit-pi-insurance-explained 26. mtc-minimum-terms-and-conditions-pi Foundational limit term + flagship SRA regulatory term. Sector-distinct.
3 2. each-and-every-claim-limit-pi-explained 21. circumstance-notification-pi-explained Limit terminology + decision-stage page. Both will draw enquiries.
4 3. retroactive-date-pi-explained 24. qualifying-insurers-sra-pi-explained Time-trigger explainer + sector-regulatory. No overlap.
5 4. run-off-cover-pi-explained 19. consumer-duty-pi-implications High-commercial-intent + regulatory. Both feed contact-page traffic.
6 7. excess-vs-deductible-pi-explained 25. assigned-risks-pool-arp-pi Money mechanics + SRA historical. Different intents, no cannibalisation.
7 6. defence-costs-inside-vs-outside-limit 22. aggregation-of-claims-pi-explained Two policy-mechanics pages. Different concepts; pair sets up advanced cluster.
8 8. policy-period-pi-explained 28. fscs-pi-cover-explained Pure definition + failure-scenario page. Sector-neutral.
9 9. civil-liability-extension-pi-explained 27. fos-jurisdiction-pi-explained Cover-scope extension + dispute-process. Complementary.
10 11. cyber-exclusion-pi-explained 17. fines-and-penalties-pi-exclusion Two exclusion pages — paired because they share intent (carve-out queries).
11 15. breach-of-contract-cover-pi-explained 29. pi-insurance-renewal-warranties-explained Coverage scope + renewal duty. Renewal page supports Q1-renewal traffic.
12 12. dishonesty-extension-pi-explained 20. pi-insurance-mta-mid-term-adjustment Niche extension + transactional process. No overlap.
13 10. pollution-exclusion-pi-explained 16. intellectual-property-infringement-pi-cover Two sector-specific scope articles (construction-adjacent + creative-adjacent).
14 14. loss-of-documents-extension-pi-explained 18. contract-works-pi-extension Two extension pages — completes the extensions cluster.
15 13. defamation-extension-pi-explained 23. following-form-pi-excess-layers Two niche, lowest-volume terms. Completes the cluster.

Pacing principles applied

Post-publication checks

  1. Indexation: confirm each article is indexed within 14 days via Google Search Console URL inspection. If not, request indexing.
  2. CTR monitoring: check Search Console CTR per article at week 4 and week 12; rewrite SEO title and meta description on any page with impressions but CTR below ~3%.
  3. Cannibalisation watch: monitor for ranking flips between a definition page and the corresponding glossary section. If they swap ranks repeatedly, consolidate the glossary entry into a 2–3 line summary and pass authority to the definition page via internal link.
  4. Quarterly review: update the last_reviewed date in frontmatter every six months at minimum; faster if regulatory position changes (e.g. SRA MTC amendment, Consumer Duty closed-products rule changes, FOS award limit movements).
  5. Schema validation: run each page through Google’s Rich Results Test for FAQPage and Article. DefinedTerm is not a Rich Results type but is a valid schema.org type and helps semantic search.
  6. E-E-A-T audit: confirm Apex’s Bristol address, FCA firm reference 724952, and Companies House number 07014570 render correctly on every page footer.
