Criterion C15 : Schema JobPosting — guide + checklist

PART 1 - Fundamentals Chapter 3 - Schema.org Keyword : schema jobposting

This criterion is discreet… until it blocks SEO performance.

The criterion **C15 — Schema JobPosting** 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 is discreet… until it blocks SEO performance.

**C15 — Schema JobPosting** (Chapter 3 - Schema.org): title, description, datePosted, validThrough, hiringOrganization for job offers

Why it matters (SEO + UX)

Why it matters: it is a lever for CTR and perception in SERP. 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: check from the browser side (render + code). Recommended tool: **Google Rich Results Test**.

  1. Test the URL in Google Rich Results Test.
  2. Validate the JSON‑LD (types, required properties, consistency with content).
  3. Check Search Console → “Enhancements” (if available) for errors/warnings.

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

How to fix properly

Strategy: make a “clean” fix (no quick patch), then measure.

  • Choose **one main type** (Article / FAQPage / LocalBusiness…) that is coherent.
  • Fill only what you can justify in the content (no invented fields).
  • Validate, then monitor errors via Search Console.

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

Concrete example (illustrative)

Example (illustrative):

  • **Context**: service landing page for a web agency in Marseille
  • **Before**: No schema (or incomplete JSON‑LD).
  • **After**: Added an Article schema consistent with the content.
  • **Note**: Objective: structure information and reduce ambiguity for the engine.
