02 — TURN VISITORS INTO BUYERS

Speed up your Shopify store without breaking what sells.

We start by checking whether speed is really what's costing you sales. When it is, the cause is usually what's been added over the years: apps you no longer use and the code they left behind, oversized images, duplicate tracking tags and extra fonts. We fix those on a copy of your theme, then place a real order to check that Meta, Google and your apps still work.

IN SHORT

Shopify speed optimization is the work of making a store's pages load and respond faster, especially on phones. We remove apps you no longer use and the code they left behind, resize images, trim theme code, scripts and fonts, and cut duplicate tracking tags. Then we measure the result with PageSpeed Insights and real-visitor data from Search Console, and check that your apps and tracking still work.

Apps you no longer use

Most apps add code to your store, and some leave it in your theme after you uninstall them. Shoppers keep downloading features you stopped paying for.

HOW WE FIX IT Unused apps and leftover code removed

A slow first screen

A full-size photo, an autoplay video or a slider at the top of the page makes shoppers on phones wait before they see anything.

HOW WE FIX IT Images and video sized for phones

Afraid to touch the tracking

Pixels, tag managers, chat and review widgets all load on every page. Nobody wants to remove one in case Meta or Google stops seeing sales.

HOW WE FIX IT Fewer scripts, with tracking still working
INSIDE THE WORK

Finding the slow parts, one page at a time.

A slow page always has causes you can list, and most were added to the store over the years. We find them page by page and judge each fix on real visitors.

FINDING CAUSES

Every slow page has a list of reasons.

Shopify names the biggest factors in a store's speed as your theme, your apps and any third-party code added by hand, including tag managers and the tags inside them. It also notes that uninstalling an app doesn't automatically remove its code from your theme. So we open your homepage, top products and main collections, and list everything each one loads, where it comes from and whether you still use it.

Then we match each cause to what it slows down. Full-size photos and sliders at the top delay the main content. Too much JavaScript from apps and tags slows how fast the page reacts to a tap, and Shopify says that's the most likely cause of a poor Interaction to Next Paint (INP), the measure of that reaction. Banners and images without set sizes make the layout jump.

  • Every script traced to the app or tag that added it
  • Leftover code from removed apps deleted
  • Each cause matched to the measure it hurts

SAFE FIXES

Made faster on a copy, then published.

We make every change on a copy of your live theme, so shoppers never see a half-finished fix. The main product photo loads first, at the size the screen needs: Shopify's image service can resize and compress each photo, as long as the theme asks for the right size. Google's guidance is not to lazy-load images that are on screen when the page opens, so only the images and widgets lower down wait until shoppers scroll.

Font files are cut to the weights you actually use, and duplicate tags go. For every app you keep, we check what it loads and where. Then we test each page on phones and desktop, publish the faster theme and place a real test order, following it into Shopify, Google Analytics, Meta and Google Ads to check that each one still records the sale.

  • Main photo first, the rest as shoppers scroll

REAL RESULTS

Judged on phone sales and real visitors.

Speed is worth paying for when it moves sales. In a 2020 study Deloitte ran for Google, mobile sites that got 0.1 seconds faster saw 8.4% more retail conversions and 9.2% higher average orders. So the number the work is for is your phone conversion rate, from Shopify's sessions by device report, before and after the change.

Speed itself is judged on real visitors. PageSpeed Insights runs one lab test on a simulated phone, and its score moves between runs, so we don't promise one. Search Console and Shopify's web performance report use real visitors' data, and Shopify's charts mark each app install and theme change, so you can see what slowed the store down. A fix takes a few weeks to show there in full.

  • Phone conversion rate compared before and after
  • Real-visitor data followed for weeks
  • No promised PageSpeed score
An example report a few weeks after a speed clean-up: real-visitor loading and tap response, the phone conversion rate, and a check that every platform still records sales.
WHAT'S INCLUDED

What we fix so your pages load fast on a phone.

Every engagement also includes the growth strategy: profit targets, a channel plan and a 90-day roadmap you approve first.

  • Before-and-after measurement

    Core Web Vitals for your key pages, from PageSpeed Insights and real-visitor data in Search Console, recorded before we change anything.

  • App clean-up

    Apps you don't use removed, along with the code they left in your theme. For every app you keep, we check what it loads, and where.

  • Images and video

    Photos served at the size each screen needs, the main image loaded first, and images and videos lower down the page loaded as shoppers scroll.

  • Theme code and fonts

    Unused sections, scripts and styles trimmed from your theme, and font files cut to the weights you use.

  • Scripts and tracking tags

    Pixels, tag managers, chat, reviews and pop-ups checked one by one. Duplicates go, and widgets lower down the page load when shoppers scroll to them.

  • Tracking checks

    A real test order once the changes are live, followed through Shopify, Google Analytics, Meta and Google Ads to check that each one records the sale.

What we need from you on day one

  • A staff account on your Shopify store
  • Access to Google Search Console
  • A list of the apps you can't do without
  • Your busiest pages
HOW WE MEASURE IT

The numbers a fast store is measured by.

Google's three Core Web Vitals, plus two numbers that show whether the speed work is paying off.

LCP
Largest Contentful Paint
How long the largest image, text block or video on screen takes to appear. Good is 2.5 seconds or less, and over 4 seconds is poor.
INP
Interaction to Next Paint
How quickly the page responds to taps, clicks and key presses, based on the slowest responses in a visit. Good is 200 milliseconds or less, and over 500 is poor. Scrolling doesn't count.
CLS
Cumulative Layout Shift
How much the layout jumps unexpectedly while someone uses the page. Good is 0.1 or less, and over 0.25 is poor.
Pages rated good
Search Console groups similar pages and rates each group by its worst metric, so one slow product template can pull down every product page.
Mobile conversion rate
The number the speed work is for. Shopify's sessions by device report shows whether phone shoppers buy more once pages load faster.

OUR APPROACH

Is speed what's costing you sales?

Often it isn't. Every theme in Shopify's Theme Store has to average a Lighthouse score of at least 60 on its home, collection and product pages before Shopify lists it. HTTP Archive's report shows that in September 2026, 76% of Shopify sites passed all three of Google's Core Web Vitals for visitors on phones, against 39% of WooCommerce sites. A slow Shopify store is usually slow because of what was added on top: apps, tags, sliders and full-size photos. Speed is worth fixing when Search Console shows your pages as Poor or Need improvement, or your phone conversion rate sits far below desktop. If neither is true, start with conversion optimization.

What usually slows a Shopify store down

Shopify names your theme, your apps and code you've added as the biggest factors in speed. Apps that edited your theme often leave their code behind when you uninstall them. Then come full-size images, sliders and autoplay videos at the top of the page, tracking tags that load twice, chat and review widgets on every page, and font files for weights nobody uses. Shopify can serve each photo at the size a phone needs, as long as your theme asks for it.

Faster, with your tracking still working

A speed clean-up goes wrong when a script gets removed and nobody notices that Meta or Google stopped seeing sales. So once the changes are live, we place a real test order and follow it through Shopify, Google Analytics, Meta and Google Ads. If your numbers were off to begin with, start with tracking. Speed work also helps your SEO and your conversion rate, because a faster page keeps more of the shoppers you've already paid to bring in. Before a big sale, work through our Black Friday checklist.

IS IT RIGHT FOR YOU?

Is speed what's holding your store back?

A good fit if

  • Your store feels slow on your own phone.
  • You've added apps, scripts and sections for years and rarely removed any.
  • Search Console shows your pages as Poor or Need improvement.
  • You're afraid to remove a script in case tracking breaks.

Not the right fit if

  • Your pages load fast but shoppers still don't buy. Start with conversion optimization.
  • You're about to rebuild the store anyway. Speed belongs in the new build: see Shopify development.
  • Your sales numbers don't match your ad platforms. Fix tracking first, so you can see what the speed work changes.

Start with what loads on every page: remove apps you don't use and the code they left behind, size images for phones, and cut duplicate tracking tags and widgets. Then test your key pages in PageSpeed Insights and watch the real-visitor data in Search Console.

Google uses three Core Web Vitals: how fast the main content appears, how quickly the page responds to a tap, and whether the layout jumps while it loads. PageSpeed Insights tests a page on demand, and Search Console shows how your pages perform for real visitors.

Usually, but we won't promise a number. The score comes from one simulated test on a phone with a slow connection, and it changes between runs. We judge the work by real-visitor data in Search Console and by your sales.

It can. Core Web Vitals are one of the signals Google's ranking systems use, though relevant content counts for more. A faster store also keeps more of the shoppers who click through from search.

Not when it's done carefully. We work on a copy of your live theme, keep the apps you need, and place a real test order once the changes are live to check that every platform still records the sale.

Some help, mostly with images. Apps that delay every script can make a speed test look better while stopping your Meta pixel or breaking parts of the page, which merchants report on Shopify's community forums. We'd rather remove what slows the store than add another app on top.

It depends on your theme, your apps and how much needs fixing. You'll get a clear price on the call.
