Why it matters: it’s a lever for CTR and perception in SERP.When it is poorly applied, we often observe: ambiguity (bad associated query), duplication between pages, or loss of performance on loading times.
On sites generated in volume, this criterion also serves as a **safeguard**: a stable rule avoids 1,000 errors at once.
Approach: tooled test (validator / performance).Recommended tool: **Screaming Frog (images)**.
Tip: first isolate 10 “representative” URLs (top pages + generated pages) before scaling the correction.
Strategy: correct the minimum necessary, then stabilize.
Next: re-crawl 50–200 URLs, then monitor Search Console over 7–14 days (impressions/CTR/indexing).
Example (illustrative):
Applying an automatic pattern that is too generic (same logic on all pages) without adding a differentiating element.
For this type of criteria, a crawl (e.g. Screaming Frog) + a targeted check in Screaming Frog (images) is generally the fastest combo.
Freeze an auto-generation rule (title/structure/schema/URLs) + add an automatic check (crawl or test) before import into production.
Validate this criterion with an audit, then deepen the method in the Academy.
