This fits when

  • Your mobile Lighthouse or Core Web Vitals scores are poor
  • You’ve uninstalled apps but their scripts still load
  • Product images are large or shift the page as it loads
  • Shoppers drop between the cart and checkout

How it works

  1. Pay and grant access

    Your store URL, the four pages to measure, and collaborator or staff access for Themes and Apps only.

  2. Measure

    Mobile Lighthouse runs and Core Web Vitals on your home, collection, product and cart pages.

  3. Fix on a duplicate theme

    Oversized images, leftover app scripts, render-blocking code, fonts, heavy Liquid loops and layout shift, plus a cart-to-checkout review.

  4. Before and after

    A report with the before and after numbers and a log of every edit. You review the duplicate theme and publish it yourself.

What the edit log looks like

The log from step 4, filled in for an example store with the numbers left out. Each row is one edit on the duplicate theme: the page it was found on, the change and how it was checked. The fixes follow App369’s Shopify speed checklist.

  1. The hero image was lazy-loaded at full size

    Page
    Home
    Edit on the duplicate theme
    Loaded first, at a width set with the image_url filter
    How it was checked
    Largest Contentful Paint, median of three mobile Lighthouse runs

  2. A snippet from an uninstalled reviews app still loaded in theme.liquid

    Page
    All pages
    Edit on the duplicate theme
    Snippet removed
    How it was checked
    The script no longer appears in the Network tab

  3. A chat widget loaded before the page was usable

    Page
    Product
    Edit on the duplicate theme
    Widget loaded after the page is usable
    How it was checked
    Total Blocking Time in mobile Lighthouse runs, before and after

  4. A loop over every variant ran for each product in the grid

    Page
    Collection
    Edit on the duplicate theme
    Loop limited to the variant the card shows
    How it was checked
    Theme Inspector for Chrome

  5. A discount bar appeared after load and pushed the page down

    Page
    All pages
    Edit on the duplicate theme
    Space for the bar reserved in CSS
    How it was checked
    Cumulative Layout Shift in mobile Lighthouse runs, before and after

  6. An upsell app added a step before checkout

    Page
    Cart
    Edit on the duplicate theme
    Not changed: flagged for you to test with and without it
    How it was checked
    Cart walked through on a phone

Sample only: written for this page for an example store, not a client’s log. The real log covers the four pages you choose, and comes with the before-and-after numbers in the report.
