Criterion K2: Source Diversity — guide + checklist

PART 1 - Fundamentals Chapter 11 - Backlinks Keyword : diversité sources

This criterion seems “simple”, but it creates many discrepancies in production.

The criterion K2 — Source Diversity is part of our SEO checklist (335 criteria). Here, you have a practical method to check and fix it — with a concrete example.

What exactly this criterion covers

This criterion seems “simple”, but it creates many discrepancies in production.

K2 — Source Diversity (Chapter 11 - Backlinks): Links from varied domains, not concentrated on 1-2 sources.

Why it matters (SEO + UX)

Why it matters: it is a UX point that eventually translates into SEO. When poorly applied, we often observe: ambiguity (wrong associated query), duplication between pages, or loss of performance on impressions.

On volume-generated sites, this criterion also serves as a safeguard: a stable rule prevents 1,000 errors at once.

How to check (step by step)

Approach: express audit (manual + 1 tool). Recommended tool: Checklist of proofs.

  1. Check for the expected signals on the page (author, proofs, NAP, sources).
  2. Control consistency across the entire site (same rules everywhere).
  3. Measure via Search Console (indexing, queries, linked pages) if applicable.

Tip: first isolate 10 “representative” URLs (top pages + generated pages) before scaling the correction.

How to fix properly

Strategy: fix the minimum necessary, then stabilize.

  • Add a real author (or “Published by …”) + profile page.
  • Add 1–3 reliable external sources when stating a fact.
  • Update the page when content changes (date if relevant).

Then: re-crawl 50–200 URLs, then monitor Search Console for 7–14 days (impressions/CTR/indexing).

Concrete example (illustrative)

Example (illustrative):

  • Context: local real estate page in Sfax
  • Before: No proof: author absent, sources absent, “anonymous” page.
  • After: Author + “About” page + external sources + update date (if relevant).
  • Note: Goal: credibility + user trust.

Checklist to tick

  • [ ] Clear author/editor
  • [ ] Respects: links from varied domains

FAQ

Frequently asked questions — K2

What is the most common mistake on “Source Diversity”?

Fixing an isolated page without correcting the template/import: the error returns in the next generation.

Which tool is the fastest for large-scale checking?

For this type of criterion, a crawl (e.g. Screaming Frog) + targeted verification in Checklist of proofs is generally the fastest combo.

How to prevent this from happening on 10K generated pages?

Freeze an auto-generation rule (title/structure/schema/URLs) + add automatic control (crawl or test) before production import.
