Criterion G31 : Index bloat avoided — guide + checklist

PART 1 - Fundamentals Chapter 7 - Technical SEO Keyword : index bloat évité

Here we talk about a criterion that often makes a difference in audits.

The criterion **G31 — Index bloat avoided** 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

Here we talk about a criterion that often makes a difference in audits.

**G31 — Index bloat avoided** (Chapter 7 - Technical SEO): No unnecessary pages indexed (tags, archives, parameters)

Why it matters (SEO + UX)

Why it matters: it is a technical quality factor (crawl, rendering, indexing). When poorly applied, we often observe: ambiguity (wrong associated query), duplication between pages, or loss of performance on Core Web Vitals.

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: tool-assisted test (validator / performance). Recommended tool: **Chrome DevTools Network**.

  1. Open the page in Chrome → DevTools → Performance/Network tab.
  2. Run Lighthouse and note the main weak point.
  3. Check if the problem repeats on “money” pages.

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

How to fix properly

Strategy: fix + add a safeguard for mass import.

  • Fix the biggest cost source (images, JS, fonts, cache).
  • Retest, then apply to the template (not page by page).
  • Add a safeguard: weight budget (KB) and CI check if possible.

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

Concrete example (illustrative)

Example (illustrative):

  • **Context**: FAQ page for aesthetic clinic in Algiers
  • **Before**: Lighthouse: 41/100 (heavy JS, unoptimized images).
  • **After**: Lighthouse: 94/100 (lazy-load, compression, cache).
  • **Note**: Goal: stabilize INP.

Checklist to tick

  • [ ] Measure before/after
  • [ ] Respects: tags
  • [ ] Improvement on template
  • [ ] No CWV regression
  • [ ] Cache and compression OK
FAQ

Frequently asked questions — G31

What is the most common mistake on “Index bloat avoided”?

Trying to “optimize” by adding too many keywords, which degrades readability and creates repetitions.

Which tool is the fastest for large-scale checking?

For this type of criterion, a crawl (e.g. Screaming Frog) + targeted verification in Chrome DevTools Network 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.
