AB Ellie: 19 #1 US Rankings — Including "Bridal Earrings" + "Wedding Earrings"
US bridal & wedding jewellery e-commerce brand on Shopify. Pre-engagement, head-term commercial keywords sat outside the top 30. Four months of full-stack e-commerce SEO — technical, collection pages, product pages, schema, content — produced 19 position #1 rankings, US-wide #1 for the two highest-volume category head terms, and an 800% year-on-year lift in non-branded organic clicks.

Fundamentals
What Is Mobile SEO and Why Does It Matter?
Google uses mobile-first indexing, meaning the mobile version of your site IS the version Google ranks. If your mobile experience is slow, clunky, or missing content, your rankings suffer across all devices — both mobile and desktop.
The impact is measurable. Sites with poor mobile experiences see bounce rates spike to 50%+ within the first three seconds of load. Conversely, businesses investing in targeted mobile SEO typically see meaningful improvements in engagement and conversion rates.
Mobile SEO covers: responsive design, viewport configuration, touch-friendly navigation, mobile page speed optimisation, and mobile-specific structured data. We also address mobile UX issues like intrusive interstitials, mis-positioned click-to-call buttons, and forms that require excessive scrolling.
As a mobile SEO agency, we audit the gap between your desktop and mobile experience and close it — because what works on desktop doesn't always work on mobile, and vice versa.

Mobile-first indexing means the mobile version of your site is the version Google ranks — across all devices.
Pricing
Mobile SEO Pricing: What to Expect
Mobile SEO is typically included within broader SEO packages (£1,300–£2,500/mo). Standalone mobile audits range from £500–£1,500 depending on site complexity.
The investment covers:
- ■ Core Web Vitals optimisation (LCP, CLS, FID)
- ■ Responsive design fixes and mobile layout issues
- ■ Mobile page speed improvements (image compression, lazy loading, server response)
- ■ Mobile-specific structured data and schema markup
- ■ Ongoing performance monitoring, regression detection, competitive benchmarking
For ecommerce sites or high-traffic portals, investment is often £3,000–£8,000/mo because mobile optimisation directly impacts revenue. A 1-second delay in mobile load time can reduce conversions by 7%. For a site generating £100K/mo, that's £7,000 per second of delay.
The ROI question isn't "What does it cost?" but "What does slow mobile cost us?" Most businesses find that mobile SEO investment pays for itself within 90 days.
Critical Update
Mobile-First Indexing: What It Means for Your Rankings
Since 2021, Google predominantly uses the mobile version of your site for indexing and ranking. If your desktop site has content, features, or internal links that the mobile version doesn't have, Google may not see them—and won't rank your pages for those opportunities.
This shift has caught many businesses off guard. Classic scenarios:
Content Gaps
Desktop version has 2,000 words; mobile version hides half via display: none CSS. Google only sees the mobile version.
Link Discrepancies
Internal navigation links present on desktop but missing on mobile—Google can't discover those pages.
Feature Loss
Desktop has interactive elements that time out or don't load on mobile, degrading user signals.
Structured Data Missing
Mobile version lacks schema markup present on desktop—rich snippets disappear from search results.
Mobile page speed is equally critical. If mobile load times exceed 3 seconds, bounce rates spike and engagement signals drop—telling Google your page isn't delivering value. We conduct a detailed mobile-first audit comparing desktop and mobile experiences side-by-side. See our technical SEO services for deeper audits.

Run the Mobile-First Health Check
Most SEO audits report mobile-first indexing as a green checkbox. That misses the point. Mobile-first means Google indexes your mobile experience first; what's not on mobile doesn't get indexed. Below is the mobile-specific health check we run on every Visionary engagement. Score yours; the gaps are usually invisible until they cost rankings.

Top 3 highest-impact failures
Mobile LCP <2.5s
Mobile LCP failure typically means hero image weight or render-blocking JS — most-impactful CWV fix.
Content parity desktop ↔ mobile (no hidden mobile content)
Hidden mobile content is invisible to Google's mobile-first crawler. What's not on mobile doesn't get indexed.
Mobile INP <200ms
Heavy JS execution and over-tracked event listeners stall touch interactions on low-CPU devices.

Mobile CWV
Mobile CWV — Why Desktop-First Audits Miss the Real Problem
Mobile and desktop CWV diverge for predictable reasons — network conditions, device CPU, render path, viewport size. Below is the breakdown of what mobile CWV measures, why each metric matters, and how we optimise each. Most accounts have desktop in green and mobile in red. Google indexes the mobile version.
| Dimension | What it measures | Mobile-specific failure modes | Visionary optimisation |
|---|---|---|---|
| LCP (Largest Contentful Paint) | Time to render largest content element | Hero image weight on mobile network; render-blocking JS; font loading | Lazy-load below fold + image-format swap (WebP/AVIF) + critical CSS inline |
| INP (Interaction to Next Paint) | Responsiveness to user input | Heavy JS execution on touch; long-running main thread; over-tracked event listeners | Defer non-critical JS + reduce third-party tags + virtualise heavy components |
| CLS (Cumulative Layout Shift) | Layout stability during load | Images/embeds without reserved space; ads loading dynamically; lazy-loaded fonts | Reserve dimensions on every image + font-display strategy + ad slot pre-allocation |
Revenue split
Where Revenue Actually Comes From — Mobile vs Desktop
Most accounts under-invest in mobile because the dashboards report desktop conversion rates. The conversion rate is higher on desktop, but the volume is lower on mobile. Below are the actual mobile-vs-desktop revenue splits across three Visionary client engagements — by vertical.
E-commerce — luxury fabrics
LADC
High-AOV luxury skews desktop for purchase; mobile is research + add-to-cart.
B2B SaaS
Rocketseed
B2B buyer-cycle skews desktop; mobile is research and brand-recognition.
Consumer e-commerce
Strictly Beds
Mid-AOV consumer purchase shifts heavily toward mobile.
Sources: Visionary client GA4 + revenue attribution Q1 2026. Splits vary by vertical, AOV, buyer cycle, and brand maturity. Mobile share grows by ~3% per year on average across the portfolio.
Audit divergence
Same Site, Two Audits — Why Findings Diverge
Run the same site through a desktop-first audit and a mobile-first audit and the findings diverge sharply. Most accounts we inherit have only ever been audited desktop-first.
| Dimension | Desktop-first audit reports | Mobile-first audit reports |
|---|---|---|
| Hero LCP | 1.8s (green) | 3.4s (red) |
| JS execution | 2.1s on main thread | 4.8s on main thread (low-CPU device) |
| Tap target failures | n/a | 14 elements below 48×48px threshold |
| Hidden mobile content | n/a | 600 words visible desktop only |
| CWV grade | Pass | Fail (LCP + INP) |
| Indexed content | What desktop renders | What mobile renders (often less) |
| Layout shifts | Rare on wider viewports | Common on mobile (image dimensions, ad slots, font swaps) |
Same site, two audits. Desktop-first reports green. Mobile-first reports red. Google indexes the mobile version.
Tap-target audit
The Tap-Target Audit Most Mobile SEO Misses
INP failures are usually tap-target failures in disguise. Below is the tap-target audit we run on every mobile engagement. It is the bit competitors miss entirely because the desktop version doesn't surface it.
- 01Minimum tap target size: 48×48px (Google guideline) — every CTA, link, button measured
- 02Spacing between adjacent tap targets: ≥8px gap — prevents misclicks
- 03Thumb-zone reachability: primary CTAs in lower-half of mobile viewport
- 04Hover-only interactions: flagged — no hover on touch devices
- 05Form input field height: ≥48px on mobile
- 06Mobile menu hamburger size: ≥48×48px
- 07Filter / sort buttons (e-commerce): ≥48×48px
- 08Pagination controls: ≥48×48px
