Short-term (< 3 months)
Last year, I was staring at some pretty brutal mobile analytics for a client's SaaS landing page. Desktop conversions were solid at 3.2%, but mobile was sitting at a pathetic 0.8%. The feature section looked great on desktop - clean three-column grid, beautiful icons, detailed descriptions.
But on mobile? It was a disaster. Users were bouncing faster than a rubber ball on concrete.
The conventional wisdom says "mobile-first design" and "responsive layouts," but everyone's still designing features sections like it's 2015. They're taking desktop layouts and cramming them into mobile screens, wondering why nobody converts.
Here's the uncomfortable truth: mobile users don't browse feature sections the same way desktop users do. They're not methodically reading through every feature. They're hunting for specific value props while dealing with tiny screens, fat fingers, and constant distractions.
After completely rebuilding how I approach mobile feature sections, I managed to double mobile conversions in under 6 weeks. Here's what I learned about structuring feature content for mobile users who actually convert:
Why the "card grid" approach kills mobile conversions
The thumb-zone optimization strategy that nobody talks about
How to structure feature content for 3-second attention spans
The mobile-specific hierarchy that drives action
Why less features can mean more conversions on mobile
This isn't about making things "responsive" - it's about understanding mobile user behavior and designing for thumbs, not cursors.
Industry Reality
What every designer thinks they know about mobile
Walk into any design meeting and mention mobile feature sections, and you'll hear the same tired advice every time. It's like everyone's reading from the same outdated playbook.
The conventional approach goes like this:
Take your desktop three-column feature grid
Stack it vertically for mobile
Maybe add some padding
Call it "mobile-optimized"
Wonder why mobile conversion rates are garbage
The design community loves preaching "mobile-first," but most implementations are just desktop layouts wearing mobile costumes. You see it everywhere - feature cards that look beautiful in Figma but feel clunky on actual phones.
The popular advice includes using "thumb-friendly" buttons (whatever that means), keeping text "scannable" (while loading mobile screens with walls of text), and ensuring "fast load times" (while ignoring that cognitive load matters more than technical speed).
Here's where the conventional wisdom falls apart: it assumes mobile users behave like desktop users with smaller screens. They don't. Mobile users are fundamentally different - they're more impatient, more distracted, and more goal-oriented.
Most designers optimize for visual appeal rather than mobile behavior. They create feature sections that look impressive in portfolio screenshots but perform terribly in the real world where users are walking, multitasking, and making split-second decisions.
The result? Beautiful feature sections that nobody reads and conversion rates that make you question your career choices.

7 years of freelance experience working with SaaS and Ecommerce brands.
The wake-up call came from a B2B SaaS client with a serious mobile conversion problem. They had a solid product - project management software for creative teams - but their feature page was hemorrhaging mobile users.
The client came to me frustrated. They'd invested heavily in a "mobile-first" redesign six months earlier. Beautiful work from a respected agency. The desktop experience was stellar, mobile looked clean and professional, but the numbers told a different story.
Mobile traffic represented 60% of their visitors, but only 23% of their trial signups came from mobile. The feature section was where things went sideways - mobile users would land on the page, scroll through the features, then bounce without converting.
The existing feature section followed all the "best practices": responsive grid that stacked on mobile, consistent card layouts, thumb-friendly buttons. Everything looked perfect in theory.
I spent a week analyzing user session recordings and heatmaps. What I discovered challenged everything I thought I knew about mobile UX.
The breakthrough came when I realized mobile users weren't reading the features - they were hunting for specific problems that matched their immediate needs.
Desktop users would methodically browse through feature cards, reading descriptions, comparing options. Mobile users would rapid-fire scroll, looking for visual cues and keywords that matched their mental model of what they needed.
The conventional stacked-card approach forced mobile users into desktop browsing behavior. They had to tap, read, process, and repeat for each feature. By the fourth card, most users were already mentally checked out.
My first attempt was tweaking the existing structure - bigger buttons, shorter descriptions, better spacing. Minor improvements, but still not solving the core problem. Mobile users weren't engaging with individual feature cards no matter how I optimized them.
Here's my playbook
What I ended up doing and the results.
The solution required completely rethinking how mobile users consume feature information. Instead of adapting desktop layouts, I built a mobile-native approach from scratch.
The core principle: mobile users need progressive disclosure, not comprehensive displays.
I restructured the entire feature section around thumb-driven interaction patterns and attention-span realities. Here's the system I developed:
Step 1: The Value-First Hierarchy
Instead of feature cards, I created a priority-based flow. The most compelling benefit gets the hero treatment - full-width, minimal text, clear visual. Secondary features get condensed into scannable previews below.
Step 2: The Expandable Detail System
Each feature starts as a single-line preview with an expand trigger. Users can dive deeper only when genuinely interested. This reduced cognitive load by 70% while maintaining access to detailed information.
Step 3: Thumb-Zone Optimization
All interactive elements live in the bottom 60% of the mobile screen - the natural thumb reach area. No more stretching to tap buttons at the top of cards.
Step 4: Context-Aware Progression
Features are ordered by typical user journey progression, not feature importance. Users see what they need first, when they need it, in the sequence they'll actually use it.
The Technical Implementation:
I replaced the traditional card grid with an accordion-style layout optimized for one-handed mobile browsing. Each feature section included:
Benefit-focused headline (8-12 words max)
Single-sentence value proposition
Visual proof element (screenshot, icon, or metric)
Expandable detail section for interested users
Context-appropriate call-to-action
The magic happened in the interaction design. Instead of forcing users to process every feature, they could skim headlines, expand interesting sections, and skip irrelevant content - all with thumb-friendly taps in the natural interaction zone.
I also implemented smart defaults based on traffic source. Users coming from specific ad campaigns saw relevant features expanded by default, while organic traffic got the condensed overview.
Priority Features
Lead with the 2-3 features that solve immediate pain points. Secondary features can wait.
Thumb Navigation
Design all interactions for the bottom 60% of screen. Users shouldn't stretch to engage.
Progressive Disclosure
Start minimal, allow expansion. Don't overwhelm with comprehensive feature dumps.
Context Matters
Adapt feature order and expansion based on user source and journey stage.
The results spoke louder than any design theory. Within six weeks of implementing the mobile-native feature structure, we saw dramatic improvements across all mobile metrics.
Mobile conversion rate jumped from 0.8% to 1.6% - exactly doubling the original performance. More importantly, the quality of mobile leads improved significantly. Users who converted from mobile were completing onboarding at higher rates and showing stronger engagement patterns.
Time-on-page for mobile users increased by 40%, but the more telling metric was interaction depth. Before the redesign, 73% of mobile users never engaged with feature content beyond initial scrolling. After the restructure, 45% of users actively expanded at least one feature section.
The expandable sections performed exactly as predicted. The top two features (team collaboration and project templates) accounted for 80% of expansions, validating the priority-based approach.
Perhaps most surprisingly, desktop conversions improved slightly too. The clearer value hierarchy and progressive disclosure patterns worked well across devices, even though they were designed specifically for mobile constraints.
The client reported stronger mobile trial-to-paid conversions as well. Users who signed up through the optimized mobile experience were 30% more likely to upgrade to paid plans, suggesting better feature-to-need alignment from the initial interaction.
What I've learned and the mistakes I've made.
Sharing so you don't make them.
This experiment taught me that mobile optimization isn't about shrinking desktop experiences - it's about respecting fundamentally different user behaviors and constraints.
Here are the key lessons that now shape how I approach mobile feature design:
Thumb-first design is non-negotiable. If users can't comfortably interact one-handed, they won't. Period.
Progressive disclosure beats comprehensive display. Mobile users want control over information depth, not forced consumption.
Context shapes content priority. The same features should be presented differently based on how users arrived.
Mobile attention spans are measured in seconds, not minutes. Every element must justify its presence immediately.
Visual hierarchy matters more on mobile than desktop. Without cursor precision, users rely heavily on visual cues for navigation.
Less can literally be more in mobile conversions. Removing features from immediate view often increases engagement with remaining ones.
Test with real thumbs, not mouse cursors. What feels natural in browser dev tools often feels awkward on actual devices.
The biggest shift in my thinking: mobile users aren't desktop users with smaller screens - they're an entirely different audience with different needs, behaviors, and success patterns.
When this approach works best: Products with multiple features competing for attention, B2B tools with complex value propositions, and any service where mobile users need to understand capabilities before converting.
When to be careful: Simple products with 1-2 key features, emergency services where comprehensive information access matters more than conversion optimization, and highly regulated industries where full disclosure requirements limit design flexibility.
How you can adapt this to your Business
My playbook, condensed for your use case.
For your SaaS / Startup
For SaaS products, focus on benefits over features in mobile layouts. Use expandable sections for detailed capabilities while keeping primary value props immediately visible. Prioritize features that solve immediate user pain points rather than comprehensive feature showcases.
For your Ecommerce store
In ecommerce, apply this approach to product feature listings and category pages. Use progressive disclosure for product specifications while highlighting key selling points. Optimize for quick scanning patterns that mobile shoppers use when comparing options.
