If there’s one thing we’ve learned after years of helping brands grow on Shopify, it’s this: most performance issues aren’t caused by obscure technical problems — they’re caused by the same handful of fixable mistakes.
So when our team audited 20 Shopify stores across different industries — beauty, fitness, apparel, home goods, B2B, custom stores, and more — we expected some variety.
Instead, we found the same issues over and over again.
And 90% of the stores shared the same core problem…
One that drags down conversions, damages SEO, and inflates ad costs.
Let’s dig into what we uncovered.
The #1 Common Issue: Bloated, Overbuilt Themes
Here’s the hard truth:
Most Shopify stores are slow — not because Shopify is slow, but because the theme is overloaded with unnecessary apps, scripts, and third-party code.
In 90% of the audits, we found:
- Themes with 20–40 unused sections still loading in the background
- Code from apps that had been uninstalled years ago
- Redundant CSS and JavaScript files loaded on every page
- Page-builders used on top of custom sections — doubling the weight
- Apps that added entire frontend frameworks just to run a pop-up or quiz
- Duplicate fonts, oversized images, and render-blocking scripts
It’s like putting a sports car on flat tires, filling the trunk with bricks, and then wondering why it’s slow.
Why this matters
A bloated theme doesn’t just slow down the site — it creates a chain reaction that hurts every aspect of your business:
- Lower conversions — Slow sites cause shoppers to bail quickly
- Higher ad costs — Meta and Google penalize slow load times
- Poor SEO — Page speed is a direct ranking factor
- Harder scaling — Small increases in traffic can lead to crashes or instability
- Expensive redesigns later — Because you eventually must rebuild it
This is the silent profit killer for many Shopify businesses.
Other Common Issues We Found (Almost as Bad)
Even outside theme bloat, there were patterns — and some were surprisingly consistent.
1. Product Pages Missing Conversion Essentials (85%)
Most product pages looked “nice,” but lacked core conversion elements:
- No clear value proposition
- Weak or generic product descriptions
- Missing comparison tables, before/after visuals, or social proof
- Reviews buried or not displayed at all
- Weak merchandising — no bundles, no upsells, no cross-sells
A beautiful product page that doesn’t sell is just decoration.
2. Poor Mobile Experience (80%)
Even in 2025, mobile UX still gets neglected.
Common issues:
- Buttons too small or too close together
- Images not optimized for mobile
- Hero sections consuming too much vertical space
- Misaligned text and stretched images
- Hidden CTAs under unnecessary sections
- Pop-ups that take over the entire screen
With mobile making up ~75% of Shopify traffic, this is an expensive oversight.
3. Disconnected Brand Storytelling (75%)
Conversion isn’t just UX — it’s connection.
But many brands made these mistakes:
- Homepage didn’t state who the brand is or why it exists
- No mission, origin story, or differentiator
- Disconnected tone between ads and site copy
- Missing trust-building elements: certifications, press, testimonials, UGC
A strong brand story increases AOV, LTV, and conversion rate — and most brands are leaving money on the table.
4. App Overload and App Conflicts (70%)
On average, each store had 18–25 apps installed — but only used about half of them.
Common problems:
- Apps injecting multiple scripts into the theme
- Overlapping functions (e.g., two apps for reviews)
- Poorly maintained apps causing API slowdowns
- Apps running on pages where they weren’t needed
- Plugins left behind after uninstalling app code
The result?
Slow load times, glitchy UX, and unpredictable bugs.
5. No CRO Strategy or Heatmap Data (65%)
Most brands had analytics installed, but didn’t use actionable data like:
- Heatmaps
- Scroll-depth tracking
- Funnel analysis
- AB tests
- Session replays
Instead, they were basing decisions on “gut feel,” design opinions, or what competitors were doing — not on real user behavior.
Why These Problems Happen (and How to Fix Them)
Most Shopify merchants don’t intentionally create messy themes or inefficient sites. These issues pile up over time:
- Multiple teams or freelancers touching the code
- Apps installed for one campaign and never removed
- New features stacked on old ones
- Lack of technical oversight
- Page-builders used to move fast early on
- Growth outpacing the site’s structure
The good news?
All of these problems are fixable — often without a full rebuild.
Here’s how we typically fix them:
Step 1: Perform a Deep Theme Audit
We identify:
- Dead code
- Duplicate scripts
- Heavy third-party libraries
- Render-blocking elements
- Old templates and unused sections
- Image and font inefficiencies
This alone can cut load time by 30–50%.
Step 2: Rebuild Key Sections Using Lightweight Code
We replace page-builder sections or bloated blocks with:
- Clean, custom code
- Modular components
- Optimized image handling
- Lazy-loading scripts
- Reduced DOM size
This makes the site faster and easier to maintain.
Step 3: Streamline Your App Stack
We remove and replace:
- Redundant apps
- Heavy scripts
- Unnecessary integrations
Often, we can replace 3–5 apps with theme-native features — saving both money and speed.
Step 4: Optimize Product Pages for Conversion
We add:
- Clear value props
- Social proof
- Bundles and upsells
- Better long-form descriptions
- Trust indicators
- Story-driven content
Product pages become more persuasive and more helpful.
Step 5: Align UX and Storytelling
We clarify:
- Brand values
- Positioning
- Key differentiators
- Messaging hierarchy
Strong brand storytelling increases conversions as much as design improvements.
What This Means for Your Store
If your Shopify site feels slow, clunky, or underperforming…
If you’ve scaled marketing but not your site experience…
If you’re running a theme that’s been “patched together” over the years…
There’s a good chance your store has the same issues we uncovered.
You’re not alone — and it’s not your fault.
But if you want to scale efficiently, these problems must be addressed.
