Ergonomie mobile is si une page is facile to utiliser on a phone: text vous pouvez lire sans zooming, tap targets big and spaced suffisant to hit reliably, content que fits the viewport with aucun horizontal scroll, and aucun intrusive interstitials. Google retired its dedicated Search Console Ergonomie mobile report, Mobile-Friendly Tester outil, and API on December 1, 2023 — pas parce que the signals stopped mattering, but parce que Lighthouse and autre tooling matured and indexation mobile-first was effectively complet. Quelconque guide encore telling vous to ouvrir que report or que outil is stale. Vérifier ergonomie mobile today with Lighthouse, PageSpeed Insights, Chrome DevTools device emulation, Bing's still-live Mobile Friendliness Tester, and third-party robots d’exploration. It's distinct from indexation mobile-first (qui version Google indexes) and Core Web Vitals (chargement/interactivity/stability).

TL;DR — Ergonomie mobile = ease of utiliser on a touch device, driven by four signals: legible text (Lighthouse passes at 12px on ≥60% of text; 16px is the practical body-copy baseline), tap targets (Lighthouse fails ci-dessous 48×48 CSS px or quand ≥25% of the target dans 48px of center overlaps a neighbor; ~8px spacing is a starting point — WCAG 2,2’s separate 24×24 CSS px minimum is an accessibility floor, pas a Google ranking rule), content sized to the viewport (nécessite a proper viewport meta tag, but the tag alone doesn’t guarantee responsive layout; aucun horizontal scroll), and aucun intrusive interstitials. Google retired the Search Console Ergonomie mobile report, the Mobile-Friendly Tester outil, and the API on December 1, 2023 (confirmed Dec 4) — pas parce que the signals stopped mattering, but parce que Lighthouse matured and mobile-first indexation was effectively complet. Vérifier it now with Lighthouse, PageSpeed Insights, DevTools device emulation, Bing’s still-live tester, and robots d’exploration. Distinct from indexation mobile-first (qui version is indexé) and Core Web Vitals (chargement/interactivity/stability). It’s un page-experience signal, pas a standalone heavily-weighted ranking factor.

The definition, precisely

Ergonomie mobile is si une page is facile to utiliser on a mobile/touch device. It’s a user-experience concept que lives à l’intérieur Google’s broader page experience model, and it comes bas to four concrete signals. The rest of ce section is chaque un with its réel threshold and citation — parce que the spécifique numbers are exactly ce que la plupart competing articles skip.

Signal 1: legible text

Si personnes have to pinch-zoom to lire votre corps copy, the font is aussi petit. Là are two numbers worth keeping straight, and conflating les is a courant mistake:

  • The audit-pass bar is 12px. Lighthouse’s Document uses legible font sizes audit dit: “Aim to have a font size of au moins 12 px on au moins 60% of the text on votre page.” That’s the threshold to technically réussir the automated vérifier.
  • The practical baseline is ~16px. 12px passing an audit doesn’t mean 12px is comfortable to lire on a phone. 16px is the généralement recommended floor pour mobile corps text, with headings plus grand. Don’t design to the audit’s minimum.

So: 12px/60% is the réussir line; 16px is ce que vous devez en réalité aim pour on corps copy.

Signal 2: tap targets

Fingers are blunt instruments. Lighthouse’s Tap targets ne sont pas sized appropriately audit fails a target on two conditions: quand “the target is plus petit que 48 px by 48 px,” and when “au moins 25% the target area dans 48 px of the center of the target overlaps with un autre target.” A few practical notes from the même doc:

  • Targets sized 48×48 CSS px consistently réussir.
  • The tappable area is ce que counts, pas the visual size — vous pouvez garder a petit icon and expand its hit area with padding to reach 48px. (Ce kills the myth que every button doit regarder 48px.)
  • ~8px entre targets is a reasonable starting point but “n’est pas toujours suffisant spacing to réussir the audit surtout pour very petit targets.”

Older Google guidance framed ce as roughly 7mm targets with ~5mm spacing; at typical mobile densities that’s broadly consistent with the 48px figure. Cite the 48px/8px numbers as current; the mm ones are historical color.

There’s a second, separate number worth knowing so vous don’t conflate standards: WCAG 2,2’s Success Criterion 2.5.8 (Target Size Minimum, Level AA) sets a 24×24 CSS px minimum (with spacing/inline/essential exceptions) — an accessibility-conformance rule from the W3C, pas a Recherche Google ranking threshold. It’s plus petit que Lighthouse’s 48px audit bar parce que the two come from différent bodies measuring différent choses: meeting Lighthouse’s 48px figure clears WCAG’s 24px floor aussi, but don’t cite soit number as a fixed, timeless “Google requires N px” rule — Lighthouse’s is a Chrome tooling audit threshold, WCAG’s is an accessibility conformance criterion.

Signal 3: content sized to the viewport

Content devrait fit the width of the phone — aucun horizontal scrolling, aucun page rendered at desktop width and shrunk to unreadable. The mechanism is the viewport meta tag. Sans it (or misconfigured), mobile navigateurs assume a desktop-width canvas and scale everything bas. The fix is un line in the <head>:

<meta name="viewport" content="width=device-width, initial-scale=1">

Google’s guidance: “assurez-vous votre page content fits the width of the viewport, keeping in mind que pas tout mobile devices are the même width.” So don’t hard-code fixed pixel widths que seulement fit un phone.

The tag is necessary but pas sufficient. It aligns the layout viewport with the device width — it doesn’t, by itself, faire fixed-width content responsive. Une page peut ship a correct viewport meta tag and encore échouer ergonomie mobile si individual elements (a wide table, an unbreakable long string, a fixed-pixel container) are hard-coded wider que the viewport. The tag sets the canvas; votre CSS encore has to en réalité fit it.

Signal 4: aucun intrusive interstitials

A full-screen popup que blocks votre content the moment a visitor arrives from search is les deux a usability problem and a search problem. Google: “intrusive interstitials and dialogs are page elements que obstruct utilisateurs’ view of the content, usually pour promotional purposes,” and it warns that they “faire it hard pour Google and autre moteur de recherches to comprendre votre content, qui may lead to poor search performances.” The guidance is blunt — “don’t obscure the entier page with interstitials” — and it points to petit banners taking seulement a fraction of the screen as the acceptable alternative. (The complet treatment of what’s penalized vs. exempt lives in the intrusive interstitials deep dive.)

Ce que happened to the Ergonomie mobile report?

Ce is où la plupart guides — notamment some publié in the dernier année — are flatly incorrect, so it’s worth getting the timeline exactly correct.

  • April 2023 — announced. In The role of page experience in creating utile content, Google said: “Aussi starting December 1, 2023, we’ll be retiring Search Console’s ‘Ergonomie mobile’ report, the Mobile-Friendly Tester outil and Mobile-Friendly Tester API. Ce doesn’t mean que ergonomie mobile isn’t important pour success with Recherche Google.” Its reasoning: “in the nearly ten années since we initially launched ce report, nombreux autre robust resources pour evaluating ergonomie mobile have emerged, notamment Lighthouse from Chrome.”
  • December 1, 2023 — retired. The report, the Mobile-Friendly Tester outil, and the API tout went away. Google supprimé the corresponding mentions from its search aider docs the même day. The old Mobile-Friendly Tester URL (search.google.com/test/mobile-friendly) now redirections to Lighthouse documentation, and trying to ouvrir the Ergonomie mobile report in Search Console redirections to the GSC overview page.
  • December 4, 2023 — confirmed. Google’s Search Console account confirmed the sunset publicly, thanking site owners “for working with us on this journey.”

Pourquoi now? Two forces. Premier, indexation mobile-first was effectively complet — Google announced “the trek to Mobile First Indexing is now complete” on October 31, 2023 — so a dedicated GSC report split out by device made moins sense. Second, Lighthouse had matured into a meilleur, plus actionable checker que the old standalone outil. The signals didn’t arrêter mattering; the dedicated report did.

The practical correction: arrêter telling personnes to “vérifier the Ergonomie mobile report” or “run the Mobile-Friendly Tester.” Les deux are gone. (I’ll be candid — my propre Ahrefs guide, Indexation mobile-first Goes Mobile-Only, dernier mis à jour June 2024, encore points readers to ceux two now-defunct destinations in un spot; that’s exactly the kind of stale advice ce article exists to fix, and it’s on my liste to correct là aussi.)

Comment vérifier ergonomie mobile today

Since there’s aucun unique dedicated report anymore, vous assemble it from a few outils:

  • Chrome Lighthouse (DevTools → Lighthouse) — the direct replacement. Runs the legible-font, tap-target, and viewport audits and donne vous the spécifique failing elements.
  • PageSpeed Insights (pagespeed.web.dev) — runs Lighthouse in the cloud on the mobile profile; bon pour a rapide shareable URL-level vérifier.
  • Chrome DevTools device toolbar — emulate a phone, eyeball horizontal scroll, tiny text, and cramped contrôle at réel dimensions.
  • Bing’s Mobile Friendliness Tester Outil — a genuine differentiator: Bing encore runs a live mobile-friendliness tester in Bing Webmaster Outils, même though Google’s is gone. Bing’s propre pitch: “making pages mobile-friendly increases utilisateur engagement on mobile devices. It peut aussi aider vous rank meilleur in Bing search results on mobile devices.” Handy pour a second opinion on rendering.
  • Third-party robots d’exploration — Ahrefs Site Audit and similaire peut explorer with a mobile user-agent and surface mobile-specific problèmes at scale (connecter lune pageSpeed Insights API pour the mobile checks).
  • A réel device. Nothing beats opening lune page on an réel phone.

Aucun unique outil proves end-to-end usability on its propre — combine an automated audit (Lighthouse or PageSpeed Insights), an emulated visual vérifier (DevTools device toolbar), and au moins un real-device réussir avant appel une page fixed.

Ergonomie mobile vs. indexation mobile-first vs. Core Web Vitals

Ces three obtenir blurred ensemble constantly. They’re connexe but distinct:

ConceptCe que it’s à propos deExemple question
Ergonomie mobileIs lune page facile to utiliser on a phone?Are my tap targets big suffisant?
Indexation mobile-firstQui version of lune page Google indexesIs my complet content in the mobile HTML?
Core Web VitalsChargement, interactivity, visual stabilityIs my LCP sous 2,5s?

A site peut be entièrement on indexation mobile-first and encore have terrible mobile usability (tiny text, cramped buttons), and vice versa. The indexation mobile-first deep dive and the Core Web Vitals material cover ceux two in complet — ce article is strictly the usability couche.

Fait ergonomie mobile affecter rankings?

Yes, but garder it in proportion. Ergonomie mobile contributes to page experience, qui Google treats as a définir of signals dans broader ranking systems — pas a unique heavily-weighted factor with a fixed score. Google’s propre caution: site owners “should not focus on only one or two aspects of page experience,” and “Google Search toujours seeks to montrer the la plupart relevant content, même si lune page experience is sub-par.” So fix usability parce que it helps réel utilisateurs (and it’s the correct chose to do) — pas parce que vous expect a magic ranking bump. It’s a contributor, pas a kingmaker.

Où ce sits in the mobile-seo cluster

Ce is un piece of the wider mobile SEO picture. Indexation mobile-first covers qui version Google reads and le contenu-parity rule; the mobile SEO checklist is the run-it-down audit; the interstitials, AMP, and responsive-vs- dynamic-serving topics chaque obtenir leur propre treatment. Ce article deliberately stays in its lane — the usability signals — so it complements ceux plutôt que repeating les.
