Speed Score: Before vs After Optimization

PageSpeed Mobile Score

After Optimization

80-90

PageSpeed Mobile Score

These scores represent typical ranges we see across Narrative stores. Your actual score depends on your specific configuration: how many products you display, which apps you've installed, your image sizes, and how many theme sections you use. A store with 5 installed apps will always be slower than one with 2 — regardless of theme choice.

Important context: Shopify's platform itself adds a baseline of JavaScript and CSS that you can't remove. This means no Shopify store will ever score a perfect 100. The scores above represent realistic, achievable targets for a well-optimized Narrative store with a reasonable number of apps installed.

Common Speed Issues with Narrative

Every Shopify theme has its own performance characteristics. Here are the speed issues we most commonly see on Narrative stores, along with why each one matters:

Full-screen hero video or image consuming significant bandwidth

This is typically the largest contributor to slow Largest Contentful Paint (LCP) scores on Narrative stores. LCP measures how long it takes for the main visual content to appear — and it's a Core Web Vital that directly affects your Google rankings.

Vertical storytelling layout loading many large lifestyle images

Third-party scripts and render-blocking resources prevent the browser from displaying your page until they've downloaded and executed. This increases both First Contentful Paint (FCP) and Time to Interactive (TTI).

Legacy JavaScript with scroll-triggered animations

Loading too many resources eagerly (before the user scrolls to them) wastes bandwidth and competes with critical above-the-fold content for network and CPU resources.

Auto-playing background video on homepage increasing LCP dramatically

Excess DOM elements and JavaScript increase the browser's rendering workload, leading to slower interaction responsiveness (measured by Interaction to Next Paint / INP).

Step-by-Step: How to Speed Up Narrative

Follow these optimization steps in order — they're arranged from highest impact to lowest. Each tip is specific to the Narrative theme and based on patterns we see across hundreds of Narrative stores.

Replace the hero video with an optimized static image — saves 1-5MB of initial load

Compress storytelling images to WebP at 80% quality under 200KB each

Disable or remove auto-play video backgrounds especially on mobile

Limit the number of story sections to 4-5 to reduce page length and image count

Add lazy loading to all below-fold storytelling images manually

Use click-to-play for any video content with a lightweight poster image

🔍 SEO bonus: Optimizing your Narrative theme's speed doesn't just improve user experience — it directly impacts your Google search rankings. Stores that pass Core Web Vitals rank higher. Speed optimization is the highest-ROI SEO investment for most Shopify stores.

The #1 Speed Factor Most Narrative Store Owners Miss

Here's what most speed guides won't tell you: your theme is probably not the main reason your store is slow.

The average Shopify store has 15-25 installed apps, and each one can inject JavaScript and CSS into your storefront. Review apps, email popups, chat widgets, analytics trackers, upsell tools — they all add up. On a typical Narrative store, third-party app scripts account for 60-80% of total JavaScript execution time.

You can optimize your Narrative images and settings all day, but if you have a heavy review app loading 200KB of JavaScript and a chat widget initializing a WebSocket connection on every page load, your speed score will still suffer.

This is exactly why we built Thunder. Instead of generic speed tips, Thunder scans every installed app on your store, measures each one's actual speed impact, and shows you exactly what's slowing you down. Then it automatically optimizes how those scripts load — deferring non-essential ones, reducing blocking time, and prioritizing critical functionality.

Thunder automatically identifies which apps are slowing your Narrative store and fixes them — no code changes required. See your speed report instantly.

Frequently Asked Questions

Why is my Narrative theme slow on Shopify?

The Narrative theme typically scores 62-72 on PageSpeed Insights out of the box. Common causes of slowness include full-screen hero video or image consuming significant bandwidth and vertical storytelling layout loading many large lifestyle images. However, the biggest speed killer for most Narrative stores is third-party app scripts — review widgets, email popups, and analytics tools that load heavy JavaScript on every page. Optimizing images and deferring non-essential scripts can improve your score to 80-90.

What is a good speed score for a Narrative Shopify store?

For a Narrative store, a realistic optimized PageSpeed score is 80-90 on mobile and even higher on desktop. The default unoptimized score is typically 62-72. Don't aim for a perfect 100 — that's nearly impossible with Shopify's platform overhead and any third-party apps. A score above 80 on mobile is considered good, and anything above 90 is excellent.

How do I speed up Narrative without breaking my store?

Start with safe, high-impact optimizations: compress all images to WebP format, remove unused apps, and enable lazy loading in your Narrative theme settings. Avoid editing theme code directly unless you're comfortable with Liquid. A speed optimization app like Thunder can automatically defer third-party scripts and optimize loading order without touching your theme files — it's the safest way to improve speed.

Is Narrative a fast Shopify theme?

Narrative is a free Shopify theme that performs reasonably well out of the box, typically scoring 62-72 on mobile PageSpeed. As a Shopify-built theme, it follows modern performance practices. However, your actual speed depends heavily on your product images, installed apps, and how many sections you use. With optimization, Narrative stores can reach 80-90.
