## Summary

Most useful for practical Shopify speed advice and technical guides for high-revenue stores.

- Best for: A campaign selling Shopify performance work to high-revenue stores needing a technical guide.
- Not for: Paid consumer brand partnerships, sponsored posts, product seeding, or reach and awareness campaigns.
- Check first: Ask for completed case study, audience data, and delivery terms before contacting.

### Takeaways

- Place key product imagery ahead of popups and app scripts.
- Load an app only on pages that need it.
- Speed work pays only when demand and offer already work.

## Main ideas

- **Load order, not file count, decides how slow a store feels**: Barratt argues that pages feel slow because images, scripts and apps all download in the first couple of seconds and crowd each other out, while browsers cannot tell which videos or assets are off screen. The remedy is to control load order: only what a shopper sees should download in that critical window; everything else can wait. Since apps rarely expose a priority setting, they suggest asking the vendor for a manual code snippet and placing it lower on the page. This also lets an app run only on the page types that need it.
- **What shoppers perceive matters more than what the file size says**: Barratt distinguishes physical from perceived speed: total files and file size can stay exactly the same while the experience changes completely, if the main visuals arrive first and loyalty, tracking and feature scripts follow. Shoppers need the product imagery, not pop-up or analytics scripts. The aim is to make waiting less painful, not rebuild the store.
- **Speed work only pays when demand and the offer already work**: Barratt cautions against treating site speed as an automatic win. Before investing, a brand should have enough traffic, a product people return for, and pricing or messaging that is no longer being tested. When those conditions hold and slow journeys are visibly costing visitors, speed can be the highest-leverage change: it affects every page and journey at once, with little risk because the store looks the same afterwards. They also rate it above small conversion-rate tests, arguing that a speed change is a bigger test than a 1-2% tweak.
- **Video should load on demand, through the native player**: Barratt calls video the heaviest single drain on a store's loading budget: a video is effectively dozens of images every second, and browsers download it even when it's off screen, hogging bandwidth needed by visuals. The first fix is lazy loading, so a video downloads only once it enters view. A further step is video facades, which download nothing until a visitor presses play, since most videos are never watched. They recommend keeping video on Shopify's native player rather than using third-party embeds.
- **Defer first — but the biggest rebuilds remove code as well**: Across the posts, the recurring method is deferral: change the order in which things load, keep every app and file, and change nothing else. One announcement describes a large project on a nine-figure store where more than 100 files were changed and roughly 4,000 lines of code removed, showing that reordering alone may not be enough at the largest scale.

## Partnerships

Izaac Barratt’s five posts offer performance consulting, not partnership packages. Each explains a Shopify speed problem and its fix: deferring app and script loading, lazy-loading video, or prioritising visual assets. Results are presented as client outcomes, including a 15% conversion lift for an apparel brand after page load times fell from about 9 seconds to about 2 seconds. Two posts point readers to a separate guide or tutorial; another invites them to comment for a recommendation on whether to defer a given app. The posts target store owners and e-commerce managers, using lead generation rather than a published sponsorship proposition. A buyer interested in a sponsored placement, paid technical walkthrough, or branded collaboration should ask about terms directly; the posts provide no rate card, media kit, sponsorship policy, deliverable specifications, or paid-partnership contact route.

## Alternatives

- Md Moktadir Hossain: Choose Md Moktadir Hossain when the agency's guide is about the landing page as a sales engine, not page-load time. Both posts offer the same diagnosis a store team can run before spending anything: confusing layout, no clear value proposition, weak product presentation, too many distractions and no visible trust signals. Hossain puts the test plainly: if a landing page cannot answer what you sell, why a buyer should trust you and why they should buy now within five seconds, traffic is being wasted. The fixes are concrete and inexpensive: a focused hero, product storytelling, reviews as proof, one call to action instead of five, and a mobile-first layout. For a guide aimed at high-revenue stores where the bottleneck is a muddled page rather than a slow one, this is the closer match. The campaign decision remains the same — publish a practical storefront-improvement guide under the agency's name for e-commerce managers — but the focus shifts from script order to page structure.
- Najmah Salam: Choose Najmah Salam when the campaign shifts from fixing a storefront to building an audience around a launch. The posts cover marketing planning that a performance guide does not: creating one substantial piece of content and remixing it into GIFs, a written devlog and short videos for several weeks; making players the heroes of the story and the marketer their guide; and sharing work in progress — concept art, funny bugs and problem solving — to build trust before release. Salam also has talks to point to: sessions on positioning a game and on twelve content marketing tips, delivered at named events, with slides available to download. For an agency planning a speaker-led webinar or co-authored guide on content across a launch calendar, the working examples and demonstrated presentation skills give the guide something Barratt's performance posts do not.
- Grace Eva: Choose Grace Eva when the client's problem is producing more paid-social creative faster, not speeding up the store. The posts describe an AI-assisted production process with no creator or camera: AI avatars that resemble creators, script and voiceover generation, product demos and B-roll, captions, and multiple ad variations for testing. Eva presents the value as faster creative testing — testing more hooks, product angles and concepts instead of waiting days or weeks for new creator footage. They also outline a workflow from idea through script, video, testing and optimisation, plus guidance on choosing an AI tool. For a guide aimed at agency clients investing in paid social who want more variations to test, this directly addresses the creative half of their growth problem. The campaign decision remains the same: publish a practical guide under the agency's name for e-commerce brands.
