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.
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.
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.
Every audit covers four pillars. Each pillar is a deep dive — not a checklist tick.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
A technical audit is most powerful when followed by these complementary services.
Mobile SEO is fundamentally a technical discipline. The audit naturally covers mobile-first indexing, mobile rendering, and Core Web Vitals — the foundational diagnostics most mobile engagements start with.
Explore →For e-commerce brands, mobile is where the majority of traffic and revenue happens. E-commerce mobile SEO is a distinct discipline given catalogue-scale technical considerations.
Explore →Local search is overwhelmingly mobile — "near me" queries are spoken from phones. Local SEO and mobile SEO are deeply intertwined disciplines for businesses with physical locations.
