Slow mobile load speed
Large unoptimized images, render-blocking scripts, and bloated themes/apps dragging load time past the 3-second threshold where bounce rate spikes.
Mobile Optimization Services
Mobile optimization that turns mobile traffic into mobile sales
More than half of your traffic is almost certainly coming from a phone, and Google has ranked mobile-first for years — yet most sites are still designed on a desktop screen first and “adapted” for mobile as an afterthought. The result is slow load times, buttons too small to tap accurately, checkout flows that break on smaller screens, and a bounce rate that quietly caps how much revenue every other channel can generate.
CoTask optimizes mobile experience for ecommerce and DTC brands in UAE, USA, and UK, treating mobile as the primary experience it actually is, not a secondary version of the desktop site. That means load speed, Core Web Vitals, tap-friendly UX, and mobile checkout flow are all built and tested mobile-first, then adapted up to desktop — not the other way around.

Problems We Fix
Common mobile experience problems we fix
Sites that come to us for mobile optimization almost always share a few of these issues.
Poor Core Web Vitals scores
LCP, CLS, and INP metrics failing Google's thresholds, directly hurting mobile search rankings.
Tap targets too small or too close together
Buttons and links that are easy to hit on a desktop mouse but frustrating to tap accurately on a phone.
Broken or clunky mobile checkout
Extra steps, forms that don't trigger the right mobile keyboard (numeric vs text), or payment options that don't render properly on smaller screens.
Desktop-first design “shrunk” for mobile
Layouts, navigation, and content hierarchy that technically fit a phone screen but weren't actually designed for how people use one.
Popups and interstitials that block content
Intrusive mobile popups that hurt both user experience and Google's mobile usability signals.
A mobile audit typically surfaces most of these within the first session — and they're usually quick wins with outsized impact on conversion rate.
What's Included
What's Included in Our Mobile Optimization Services
Seven disciplines run as one program — speed and Core Web Vitals first, then mobile UX, checkout flow, and mobile SEO on top of a fast foundation.
Mobile Speed Optimization
Image compression and lazy loading, script and font optimization, caching strategy, and Core Web Vitals fixes (LCP, CLS, INP) so pages load fast on real-world mobile connections, not just fast on a fiber office connection.
Mobile UX & Interface Audit
Reviewing navigation, tap target sizing, font legibility, and content hierarchy specifically for mobile screens, then redesigning what's actually hurting usability rather than guessing.
Mobile Checkout Optimization
Streamlining the mobile checkout flow — fewer steps, correct input types triggering the right mobile keyboard, visible and trusted payment options — since checkout friction on mobile is one of the highest-impact conversion leaks on any ecommerce site.
Responsive Design Fixes
Correcting layout breakpoints, image scaling, and component behavior across phone and tablet screen sizes, so the experience holds up on every device, not just the one used for testing.
Mobile SEO
Mobile-first indexing readiness, structured data validation on mobile, and mobile usability reporting through Google Search Console.
Testing Across Real Devices
Testing on actual iOS and Android devices and browsers, not just browser dev tools, to catch rendering and performance issues that simulators miss.
Reporting
Before-and-after Core Web Vitals scores, mobile conversion rate tracking, and monthly reporting tied to GA4 mobile segment data.

Scale & Report
Ongoing monitoring for speed regressions (a common side effect of new app installs or content updates) and monthly Core Web Vitals and conversion reporting.
Most sites see measurable speed and Core Web Vitals improvement within the first 2 weeks; mobile conversion rate improvements typically build over 30-60 days as the changes compound with normal traffic.
