Mobile-first
is just first.

Technical SEO Audit. Mobile-first indexing is now indexing. Crawlability, indexability, Core Web Vitals, schema, internal architecture — examined with surgical rigour, prioritised by commercial impact.

The Thesis

Most companies still QA their websites on desktop.
Google doesn't. Hasn't for years.
Mobile-first indexing means the mobile version of your site
is the version Google sees. The desktop version is increasingly
a courtesy. The mobile experience is the brand experience
for everyone Google introduces to you.

What we actually do

Where Google sees your mobile site only.

Google's mobile-first indexing transition completed years ago. Today, Google's primary index is the mobile version of every site — desktop is a fallback at best. Most teams still build, test, and QA on desktop, then check that mobile "works" before launch. By that point, the mobile experience has already been compromised by decisions made for the desktop layout.

Real mobile SEO inverts that workflow: the mobile experience is the primary design constraint, and desktop is the version that gets adapted upward. That changes how Core Web Vitals get prioritised, how images get loaded, how navigation gets structured, and how content gets paginated. The brands that adopt the inversion compound; the ones that don't lose ground continuously.

Talk to a strategist

What's included.

Every audit covers four pillars. Each pillar is a deep dive — not a checklist tick.

i. Vitals

Mobile Core Web Vitals

LCP, INP, CLS measured on real mobile devices, not desktop emulators. Field data analysis from CrUX, lab testing from Lighthouse, real device testing on the actual phones your audience uses. The metrics Google uses for ranking, measured the way Google measures them.

ii. UX

Mobile UX Auditing

Tap target sizing, font legibility, viewport configuration, intrusive interstitial detection, mobile navigation usability. The UX layer Google explicitly measures and increasingly enforces through ranking signals.

iii. Strategy

AMP / PWA Decision Framework

Whether your site needs AMP (rarely, in 2026), needs PWA features, or just needs better-engineered standard mobile HTML. The strategic decisions most teams over-engineer or under-engineer at significant cost.

iv. Rendering

Mobile Rendering Audit

How Googlebot Mobile renders your site, what JavaScript-dependent content it sees vs. misses, where mobile-specific rendering issues silently suppress indexing. The technical layer most teams have wrong without knowing.

How a technical audit unfolds.

i. Audit

Real-device baseline

Test on real mobile devices across the audience's actual hardware. CrUX field data analysis, Lighthouse lab testing, mobile UX QA. Most audits surface 30-50 issues invisible from desktop testing.

ii. Prioritise

Impact-ranked roadmap

Issues sorted by Core Web Vitals impact, conversion impact, and engineering cost. Quick wins (image optimisation, font loading) typically deliver visible Vitals improvement in 30-60 days.

iii. Engineer

Mobile optimisation

Working with your engineering team (or executing directly) on the technical fixes: image strategy, font loading, JavaScript bundle reduction, layout shift elimination, viewport configuration. Mobile-first remediation, not desktop-first afterthought.

iv. Monitor

Continuous mobile QA

Mobile UX regressions are easy to introduce — every code release risks degrading Core Web Vitals or breaking mobile rendering. Monthly monitoring catches regressions before Google's ranking systems do.

compounding vs leaking · placeholder
Why it matters

Where the experience
is the ranking.

Google's ranking systems explicitly use mobile experience signals — page speed, layout stability, interaction responsiveness, intrusive interstitials. These aren't soft signals or tie-breakers; they're direct ranking factors that can suppress otherwise strong content. A site with great content and bad mobile UX consistently underperforms a site with adequate content and excellent mobile UX.

The brands that treat mobile as the primary experience compound. The brands that treat it as a checklist item don't. Mobile SEO isn't a specialist subset of SEO anymore — it's the foundation layer on which all other SEO investments either compound or leak.

Featured case · Premium Homeware Brand

A €40M Shopify Plus retailer had a mobile LCP of 5.2 seconds. Mobile-first remediation cut it to 1.8 seconds — and rankings followed.

A premium homeware brand on Shopify Plus had a mobile LCP of 5.2 seconds and was failing Core Web Vitals on 80% of mobile templates. We rebuilt image loading strategy, eliminated render-blocking JavaScript, optimised font loading, and rebuilt the above-the-fold rendering. Ninety days later, mobile LCP was 1.8 seconds, all Core Web Vitals were passing, and organic mobile rankings improved across 200+ priority queries.

Read the full case

We'd been told for two years that our mobile site was "fine" by various agencies. Revolutionize spent two weeks on the audit and showed us we were failing Core Web Vitals on most templates — without anyone noticing because nobody was looking at real device data. Three months later we were passing on every metric, and rankings followed within the quarter.

Questions worth asking.

Isn't mobile SEO just regular SEO?+
Increasingly, yes — mobile is the default. But that's exactly why dedicated mobile attention matters. Most teams have built workflows around desktop QA and treat mobile as a check-the-box afterthought. The discipline of treating mobile as primary is rare enough that brands which adopt it gain meaningful advantage.
Do we still need AMP in 2026?+
For most sites, no. Google deprecated the AMP requirement for Top Stories in 2021, and modern HTML can hit AMP-equivalent performance with proper engineering. AMP still makes sense for some publisher use cases and specific ad-revenue scenarios, but for the typical brand site or e-commerce site we usually recommend against it. The strategic decision deserves analysis case by case.
What about PWAs?+
PWA features (offline support, install-to-homescreen, push notifications) are valuable for engagement but don't directly affect SEO. We recommend PWA capabilities for sites where return-visitor patterns justify the engineering investment — not for SEO purposes specifically.
How long until mobile work shows ranking impact?+
Core Web Vitals improvements: 60-120 days for ranking impact (Google needs to re-crawl with field data updates). Mobile UX issues: 30-90 days for ranking impact (faster signal). Material organic traffic shift from mobile work: typically 4-8 months.
What does mobile SEO cost?+
Initial mobile audit and optimisation roadmap: €5,000-€12,000. Implementation work alongside engineering teams: €3,000-€8,000 per month for ongoing optimisation. Catalogue-scale e-commerce mobile programmes: scoped separately. Most engagements are integrated into broader SEO retainers. Every engagement starts with a free 30-minute scoping call.
