Guide Mobile SEO Checklist

TL;DR — Mobile SEO is now simplement SEO. Google indexes and ranks votre site en utilisant the mobile version of votre pages, so the checklist comes bas to three choses: assurez-vous votre mobile pages have the même content as desktop, assurez-vous ils charger fast and feel responsive on a phone, and assurez-vous they’re facile to utiliser with a thumb. And ignore the old Mobile-Friendly Tester — Google killed it.

Pourquoi mobile SEO is the whole game now

Pour années “mobile SEO” was a side project — vous optimized pour desktop, alors made certain le site didn’t regarder broken on a phone. That’s over. Since July 2024 Google uses seulement the mobile version of votre page to decide how vous rank, pour everyone — notamment personnes searching on a desktop. Si votre phone version is worse que votre desktop version, que worse version is the un Google judges vous on.

So the modern mobile SEO checklist is short to dire and important to obtenir correct:

1. Même content on mobile as desktop (“content parity”)

Ce is the big un. Whatever vous vouloir Google to voir — votre headings, votre corps text, votre images and leur texte alternatif, votre lien internes, votre données structurées — has to be présent in the mobile version of lune page. Si votre mobile template quietly drops a section, hides a paragraph by removing it from lune page (pas simplement collapsing it), or trims votre lien internes, Google may jamais voir que content.

Hiding content à l’intérieur tabs or accordions on mobile is fine — Google encore reads it tant que it’s en réalité in lune page’s code. The problem is content that’s truly manquant.

2. Speed and responsiveness on a phone (Core Web Vitals)

Google measures three “Core Web Vitals” separately pour mobile and desktop:

• LCP — how fast the biggest chose on screen loads (aim pour 2,5 seconds or moins).
• INP — how quickly lune page reacts quand vous tap (aim pour 200 milliseconds or moins).
• CLS — how beaucoup lune page jumps autour as it loads (aim pour 0,1 or moins).

Mobile usually scores worse que desktop parce que phones have slower networks and slower chips. The unique la plupart courant, la plupart damaging mistake: lazy-loading votre principal hero image. Don’t. Lazy-load images ci-dessous the fold, jamais the big un at the top.

3. Facile to utiliser with a thumb

• A correct viewport tag so lune page fits the screen: <meta name="viewport" content="width=device-width, initial-scale=1">.
• Tap targets big suffisant to hit — à propos de 48×48 pixels, with a little space entre les.
• Corps text au moins 16px so nobody has to pinch-zoom.
• Aucun giant popup covering lune page the moment someone arrives from search.

The outils you’ve heard of are gone

Si a guide indique vous to “run Google’s Mobile-Friendly Test,” it’s out of date. Google retired que outil and the Ergonomie mobile report in Search Console in December 2023. Utiliser ces à la place: PageSpeed Insights (pagespeed.web.dev), Lighthouse in Chrome, the Inspection d’URL outil in Search Console, and the Core Web Vitals report.

Vouloir the complet audit version — content parity edge cas, the LCP lazy-loading trap with Google’s propre admission, INP vs. the old FID metric, interstitial exemptions, the AMP reality, and how Bing differs? Switch to the Avancé tab.

TL;DR — Indexation mobile-first is complet (finalized July 5, 2024) — Google uses votre mobile HTML to rank vous pour tout requêtes on tout devices. So the checklist is: (1) content parity — même corps text, titles/descriptions, headings, images, texte alternatif, lien internes, and données structurées on mobile as desktop; (2) Core Web Vitals on mobile — LCP ≤ 2,5s (jamais lazy-load the LCP image), INP ≤ 200ms (INP replaced FID on March 12, 2024), CLS ≤ 0,1; (3) usability — correct viewport, 48×48px touch targets, ≥16px font, aucun intrusive interstitials (with réel exemptions); (4) audit with current outils — Lighthouse, PageSpeed Insights, URL Inspection, and the CWV report, parce que the Mobile-Friendly Tester and GSC Mobile Usability report were retired December 2023. Responsive design is Google’s recommended setup. AMP donne aucun ranking advantage since June 2021. Bing fait pas utiliser indexation mobile-first.

Confidence: high · Verified: 2026-07-14 Google Search Central: Mobile-first indexing Evidence for this claim Google recommends responsive web design as the easiest mobile configuration to implement and maintain. Scope: Google's implementation recommendation; other supported configurations can work. Confidence: high · Verified: 2026-07-14 Google Search Central: Mobile site configurations

The baseline: indexation mobile-first is finished

Ce is the context que rend everything sinon faire sense. Google announced majority completion of indexation mobile-first in October 2023, and the final enforcement landed July 5, 2024: quelconque site que wasn’t accessible to Googlebot Smartphone simply stopped being indexé. Là is aucun desktop-first exploration left.

The implication is the un personnes encore under-rate: the mobile version of votre page is the version que determines votre rankings pour every requête, on every device — notamment desktop searches. Vous ne sont pas optimizing “a mobile experience” off to the side; you’re optimizing the canonical version of votre site.

1. Content parity — the #1 technical requirement

Si vous fix un chose on ce liste, fix ce. Google’s guidance is explicit: “Faire certain que votre mobile site contient the même content as votre desktop site.” Que signifie headings, corps text, images, texte alternatif, and lien internes tout besoin to match entre versions, and “Assurez-vous que the title element and the meta description are equivalent à travers les deux versions.”

Practical parity checks:

• Corps content présent on mobile, pas stripped by a leaner mobile template.
• Titles and meta descriptions equivalent à travers versions.
• Headings (the même H1/H2 structure) présent in the mobile HTML.
• Images with the même descriptive texte alternatif, captions, filenames as desktop.
• Lien internes présent on mobile — don’t drop votre lien graph in a “simplified” mobile nav.
• Don’t “lazy-load primary content upon user interaction” — si content seulement apparaît après a tap, Google may pas voir it.

Two parity nuances worth internalizing: tabs and accordions are fine. Content reorganized into collapsible UI is encore indexé tant que it’s in the DOM — the myth que hiding content in accordions hurts SEO is simplement que. The réel échec mode is content that’s supprimé from the markup entirely on mobile. And robots meta tags doit match — “Use the same robots meta tags on the mobile and desktop site” — or vous pouvez accidentally noindex the version Google en réalité uses.

2. Données structurées parity

Même rule, applied to schema. Google’s December 2018 guidance: “Si vous utiliser données structurées on the desktop versions of votre pages, vous devez have the même données structurées on the mobile versions of lune pages, since with mobile-first indexation, we’ll seulement utiliser the mobile version of votre page pour indexation.” Validate it with the Résultats enrichis Tester (encore active — pas deprecated). Pour separate-URL (m-dot) setups, l’URLs à l’intérieur votre données structurées doit référence the correct mobile URLs.

3. Crawlability and robots

• Don’t block resources (CSS, JS) in robots.txt que are nécessaire to render the mobile page — si Google can’t render it, it can’t voir votre parity.
• Robots meta tags identical à travers versions (ci-dessus).
• Pour separate URLs, obtenir canonicalization correct: the desktop canonical on les deux versions, rel="alternate" on desktop pointing to the mobile URL.

4. Core Web Vitals on mobile

Google measures CWV “segmented across mobile and desktop devices” at the 75th percentile, and “Core Web Vitals are used by our ranking systems.” Mobile is où the gap montre up — slower networks and CPUs mean roughly 48% of mobile pages réussir tout three vs. ~56% of desktop, with LCP and INP driving the difference.

The thresholds (bon / nécessite improvement / poor):

• LCP — ≤ 2,5s / 2,5–4,0s / > 4,0s.
• INP — ≤ 200ms / 200–500ms / > 500ms.
• CLS — ≤ 0,1 / 0,1–0,25 / > 0,25.

LCP — jamais lazy-load the hero image. Ce is the unique la plupart damaging mobile performances mistake, and it’s everywhere. web.dev is blunt: “Jamais lazy-load votre LCP image, as que va toujours lead to unnecessary resource charger delay, and va have a negative impact on LCP.” Hint priority à la place with fetchpriority="high" (a preload or directement on the <img>). Google’s propre Martin Splitt admitted Google shipped ce bug: leur CMS “defaults tout images to lazy chargement, qui n’est pas great.” Si Google peut do it by accident, so peut vous.

INP — and pourquoi it’s pas FID. INP (Interaction jusqu’au prochain affichage) replaced FID on March 12, 2024. FID seulement mesuré the delay avant le navigateur pourrait begin processing the premier interaction; INP measures the worst interaction delay à travers the entier page lifetime. Que rend it far plus sensitive to slow JavaScript on mobile, où touch events on weak CPUs blow past the 200ms threshold easily. Si votre older audit notes encore talk à propos de FID, they’re stale.

CLS — reserve space. Définir explicit width and height (or aspect-ratio) on images and embeds, reserve space pour ads and late-loading content, and don’t inject content ci-dessus the fold après charger.

5. Images and videos on mobile

• Utiliser modern formats (WebP/AVIF) and pris en charge formats seulement — a JPG à l’intérieur inline SVG won’t be indexé.
• Responsive images via srcset + sizes; explicit width/height to prevent CLS.
• Don’t utiliser images que are aussi petit or low-resolution, and éviter constantly-changing image URLs (per-page-load URL generation breaks image indexation).
• Identical texte alternatif, titles, captions, filenames to desktop.
• Videos: pris en charge formats in valid HTML tags (<video>, <embed>, <object>), stable URLs, matching video données structurées, placed prominently to minimize scrolling.

6. Ergonomie mobile

• Viewport: <meta name="viewport" content="width=device-width, initial-scale=1">. width=device-width is mandatory. Éviter maximum-scale=1 or user-scalable=no — ils block pinch-zoom and Google flags les as accessibility violations. Sans a viewport tag at tout, mobile navigateurs render at ~980px desktop width and shrink, qui is unusable.
• Touch targets: 48×48 CSS pixels minimum, with au moins 8px spacing entre adjacent targets (Lighthouse / Material Design standard).
• Font size: ≥16px corps text to éviter the “text too small to read” flag.
• Formulaires: utiliser appropriate input types (tel, email, number) so phones montrer the correct keyboard.

7. Interstitials and ads — and the exemptions

The “any popup will tank your rankings” framing is overstated. What’s penalized is the intrusive kind: “Don’t obscure the entire page with interstitials” and “Don’t redirection the utilisateur to a separate page pour leur consent or input” — full-screen popups avant the utilisateur engages, standalone interstitial pages.

What’s explicitly allowed: legally requis cookie consent banners, login dialogs pour genuinely paywalled content, petit banners en utilisant reasonable screen space, and age gates requis by law. And remarque the ranking nuance — the interstitials signal is pas a Core Web Vitals metric. As Google puts it, “Au-delà Core Web Vitals, autre page experience aspects don’t directement aider votre website rank plus élevé in résultats de recherche. Cependant, ils peut faire votre website plus satisfying to utiliser.” Pour ads, follow the Meilleur Ads Standard.

8. AMP: neutral, pas dead, pas requis

AMP lost its ranking advantage in June 2021, quand Google supprimé the AMP requirement pour Top Stories eligibility. Quelconque page with bon Core Web Vitals peut apparaître in Top Stories now. AMP pages encore function — ils simplement offer aucun SEO benefit over a well-optimized standard page. Si you’re on AMP today, weigh migration cost contre benefit; the SEO incentive to adopt it is gone.

9. Site configuration: responsive is the recommended chemin

Three setups, in Google’s order of preference:

1. Responsive design (recommended): même HTML on the même URL; CSS handles layout. Un URL, aucun duplication risk, aucun parity gap by construction.
2. Dynamic serving: même URL, différent HTML by user-agent. Risk: accidentally serving desktop HTML to mobile utilisateurs.
3. Separate URLs (m-dot): différent HTML on différent URLs. Exige careful canonicalization and the la plupart parity discipline. John Mueller’s long-standing advice: “At some point tout of ces sites with separate mobile URLs devrait simplement déplacer to a responsive design.”

10. Audit with current, non-deprecated outils

Ce is the credibility vérifier on quelconque 2025-era mobile checklist. Google retired the Mobile-Friendly Tester outil, the Mobile-Friendly Tester API, and the GSC Ergonomie mobile report in early December 2023. Leur statement: “Today we’re sunsetting Search Console’s Ergonomie mobile report, Mobile-Friendly Tester outil and Mobile-Friendly Tester API,” reasoning that “nombreux autre robust resources pour evaluating ergonomie mobile have emerged.”

Utiliser ces à la place:

• PageSpeed Insights (lab + field, mobile tab).
• Lighthouse (Chrome DevTools, mobile mode).
• GSC Core Web Vitals report (field données, filter to mobile).
• GSC Inspection d’URL (how Googlebot renders a spécifique page).
• Résultats enrichis Tester (validates données structurées).
• CrUX Vis (cruxvis.withgoogle.com) — the CrUX Dashboard was deprecated; CrUX Vis is Google’s current historical field-data outil pour mobile CWV trends.

Bonus: Bing is différent — desktop-first

A genuine divergence la plupart guides miss: Bing ne fait pas utiliser indexation mobile-first. Bing’s principal explorer target remains the desktop version of votre pages. Mobile-friendliness has been a Bing ranking signal since 2015, but it n’est pas Bing’s indexation methodology. So mobile parity encore matters pour Bing — pour ranking raisons, pas parce que Bing seulement sees votre mobile HTML. Utiliser Bing Webmaster Outils to monitor mobile-related explorer errors, submit sitemaps, and validate données structurées.

AI summary

A condensed prendre on the Avancé version:

• Indexation mobile-first is complet (finalized July 5, 2024). Google ranks vous on votre mobile HTML pour tout requêtes on tout devices, notamment desktop searches.
• Content parity is rule #1. Même corps text, titles/meta descriptions, headings, images + texte alternatif, lien internes, robots meta tags, and données structurées on mobile as desktop. Tabs/accordions are fine; manquant content n’est pas.
• Core Web Vitals, mesuré separately pour mobile: LCP ≤ 2,5s, INP ≤ 200ms, CLS ≤ 0,1, at the 75th percentile. Mobile lags desktop (~48% vs ~56% passing).
• Jamais lazy-load the LCP image — the la plupart courant, la plupart damaging mobile mistake; utiliser fetchpriority="high". Google admitted shipping ce bug itself.
• INP replaced FID on March 12, 2024 — it measures tout interactions à travers the page lifetime, pas simplement the premier, so it’s harsher on slow mobile JS.
• Usability: correct viewport (aucun user-scalable=no), 48×48px touch targets, ≥16px font, mobile-appropriate formulaire input types.
• Interstitials have exemptions: cookie consent, paywall logins, petit banners, legal age gates are allowed; the signal isn’t a CWV metric.
• AMP is neutral — aucun ranking advantage since June 2021; encore functional.
• Responsive design is Google’s recommended setup (vs. dynamic serving and m-dot).
• Outils: Lighthouse, PageSpeed Insights, Inspection d’URL, CWV report, Résultats enrichis Tester, CrUX. The Mobile-Friendly Tester and GSC Ergonomie mobile report were retired December 2023.
• Bing ne fait pas utiliser indexation mobile-first — it’s desktop-first; mobile-friendliness is a ranking signal, pas its indexation méthode.

The mobile SEO checklist

Fonctionner top to bottom. The premier groupe is non-negotiable; the rest sharpen it. Clearing every box ci-dessous removes the technical blockers Google has named — it doesn’t guarantee rankings, indexation, or identical search-result treatment. Content quality and relevance encore decide the rest.

Content parity (the #1 requirement)

• Mobile page contient the même corps content as desktop (nothing stripped by a leaner mobile template).
• Title and meta description are equivalent à travers mobile and desktop.
• Même heading structure (H1/H2…) présent in the mobile HTML.
• Même images with the même descriptive texte alternatif, captions, filenames.
• Même lien internes présent on mobile.
• Données structurées matches desktop (validate with the Résultats enrichis Tester).
• Robots meta tags identical à travers versions (aucun accidental mobile noindex).
• Aucun principal content lazy-loaded on utilisateur interaction (tap-to-reveal).

Technical setup

• INP ≤ 200ms — audited as INP, pas the retired FID.

Mobile SEO cheat sheet

Ce que to vérifier → outil → réussir/échouer

Core Web Vitals thresholds (mobile, 75th percentile)

Fast facts

• Indexation mobile-first completed July 5, 2024 — mobile HTML ranks vous everywhere.
• INP replaced FID on March 12, 2024.
• Mobile-Friendly Tester + GSC Ergonomie mobile report retired December 2023.
• AMP — aucun ranking advantage since June 2021 (Top Stories ne … plus exige it).
• Bing — desktop-first; mobile-friendliness is a ranking signal, pas its index.

The mental models

1. Mobile is the canonical version. Arrêter thinking “desktop site + a mobile experience.” Since July 2024 the mobile HTML is the version Google indexes and ranks pour everyone. Every audit question becomes: “What does Googlebot Smartphone actually see on this page?”

2. Parity → Performances → Usability, in que order. Si content is manquant on mobile, aucun amount of speed tuning saves lune page — Google can’t rank content it jamais sees. Obtenir parity correct premier, alors chase Core Web Vitals, alors polish thumb-level usability. Spending CWV effort on une page with a parity gap is optimizing the incorrect couche.

3. Field données, pas lab données, is the ranking input. Lighthouse donne vous a lab score in a controlled environment; CrUX/GSC give vous réel utilisateurs’ field données at the 75th percentile, and that’s ce que the ranking systems utiliser. Utiliser the lab to diagnose, the field to judge. A green Lighthouse run with poor field CWV is encore a problem.

4. “Use X instead of Y” — the tool-currency rule. The fastest credibility tell in mobile SEO is si someone encore recommends dead outils. Mobile-Friendly Tester → Lighthouse / PageSpeed Insights. GSC Ergonomie mobile report → CWV report + Inspection d’URL. FID → INP. Si votre traiter références the left side of quelconque of ceux arrows, it’s stale.

5. Penalties have exemptions — lire the réel rule. Interstitials don’t universally tank rankings; the rule targets intrusive ones, and cookie consent, paywall logins, petit banners, and legal age gates are exempt. Quand a “rule” sounds absolute, vérifier the source pour the carve-outs avant vous redesign autour a myth.

Monthly mobile SEO health vérifier

1. Examiner mobile field données. Ouvrir the Search Console Core Web Vitals report and PageSpeed Insights pour representative templates. Record affected URL groupes and the metric que modifié. Fait signifie every nouveau problème has an owner or a documented raison to monitor.
2. Sample content parity. Comparer mobile and desktop crawls pour titles, robots, canonicals, headings, principal copy, lien internes, images, and données structurées. Fait signifie material differences are soit intentional layout changements or tickets.
3. Inspect modifié templates as Googlebot Smartphone. Utiliser Inspection d’URL pour a sample from chaque recently released page type. Fait signifie principal content and signals apparaître in rendered HTML sans interaction.
4. Run hands-on usability checks. Tester courant phone widths pour zoom, horizontal overflow, touch targets, formulaires, navigation, and interstitials. Fait signifie blocking defects are reproducible and assigned.
5. Annotate and comparer performances. Segment Search Console mobile performances by template and record releases, migrations, and campaigns. Fait signifie anomalies have a scoped investigation plutôt que an unqualified site-wide conclusion.

Mobile audit mistakes to éviter

En utilisant retired Google outils as the audit plan

The Mobile-Friendly Tester and Search Console Ergonomie mobile report are gone. Utiliser Lighthouse, PageSpeed Insights, Inspection d’URL, the Core Web Vitals report, and direct device testing.

Checking seulement visual layout

Une page peut regarder responsive pendant que mobile HTML omits copy, liens, directives, images, or données structurées. Comparer indexable output, pas screenshots alone.

Lazy-loading the LCP image

Deferring the principal visual delays the resource que defines LCP. Garder it discoverable in initial markup and prioritize it à la place.

Treating accordion content as manquant content

Collapsed content n’est pas the problem quand it remains in the DOM. Focus on content que the mobile template removes or loads seulement après interaction.

Applying un lab score to the whole site

Un Lighthouse run is diagnostic, pas representative field performances. Sample page types and pair lab findings with mobile field données.

Courant mobile SEO audit échecs

Mobile HTML is manquant desktop content

Symptom: A explorer diff montre fewer headings, liens, images, or schema items on mobile. Probable causer: Separate templates or user-agent rules have drifted. Fix: Restore the elements from the shared content source and confirmer les with a mobile récupérer plus Inspection d’URL.

Lighthouse semble bon but field données is poor

Symptom: A controlled lab run passes pendant que mobile Core Web Vitals groupes échouer. Probable causer: Réel devices, networks, interactions, or templates differ from the unique tester. Fix: Identifier affected URL groupes and metric distributions, reproduce on representative devices, and optimize the shared bottleneck plutôt que the sample URL alone.

Pages overflow horizontally on some phones

Symptom: Utilisateurs doit pan sideways despite a viewport meta tag. Probable causer: A fixed-width child, long unbroken valeur, table, media embed, or transformed element exceeds its container. Fix: Inspect the overflowing node at the failing width, constrain responsive media, and retest zoom plus landscape layouts.

Prompts pour mobile SEO auditing

Triage a mobile/desktop explorer diff

Review this crawl comparison with mobile and desktop columns for status, title,
robots, canonical, H1, word count, internal-link count, image count, and structured
data types. Identify material content-parity exceptions, separate likely layout-only
differences, group issues by template, and give a direct verification step for each
group. Do not infer missing content from count differences alone.

Convert field-data findings into tickets

Turn these mobile Core Web Vitals findings into implementation tickets. For each URL
group, preserve the observed metric and evidence, distinguish field data from lab
diagnostics, list the most likely shared template causes as hypotheses, and define a
pass/fail validation step. Do not invent a cause or promise a ranking change.
