BeeFriendly Skincare: $48K to $1.45M annual revenue from a 2.24-second LCP reduction.

The challenge

BeeFriendly was a small Shopify supplements DTC store generating $48,000 in annual revenue. The product was proven, the ad spend was working, but conversion was capped: 82% bounce rate, 1.79% conversion rate (vs 3.8% industry benchmark), 12.48-second average page load. Nobody was waiting long enough to read the offer.

What we did

Three theme-code edits. Image compression and WebP conversion on hero and product imagery. Removal of three render-blocking scripts firing synchronously above the fold. Tuning Shopify's image-renderer to match actual hero dimensions. Total dev time: 8-10 hours. LCP dropped 2.24 seconds.

The result

Annual revenue climbed from $48,000 to $1,447,225 — roughly 30× growth. Bounce rate dropped from 82% to 38%. Per-visitor value rose from $1.10 to $29.03. Sustained 6+ months without regression.

Why it worked

Page speed is rarely treated as a CRO discipline because the work is engineering-shaped, not copy-shaped. But on a sub-£100K-monthly store with proven product-market fit, page speed is often the single highest-leverage intervention. The 2.24-second LCP fix produced 95% of the lift before any secondary lever was touched.

ClickBoost: 150MB to 2.5MB page weight, mobile score 36 to 74 in 11 days.

The challenge

ClickBoost is a Glasgow-based paid-media agency running case-study videos for 13+ named brand wins on their homepage hero carousel. Aggregate page weight: 150 MB. Mobile PageSpeed: 36/100. Total Blocking Time: 1,120ms. An agency selling paid-media credibility cannot have a homepage that fails the basics of digital experience.

What we did

Three layers in 11 days. HandBrake 2-pass encoding compressed 10 video assets from 138.74 MB to 17.2 MB total. A custom IntersectionObserver script loaded MP4s only when the user scrolls within 500px of the widget. Globally dequeued Google's recaptcha (278 KB unused on every page) and activated WP Rocket's Delay JavaScript Execution for all third-party trackers.

The result

Mobile Performance: 36 → 74 (+105%). LCP: 7.5s → 4.7s. Total Blocking Time: 1,120ms → 10ms (-99.1%). Total page weight: 150 MB → 2.5 MB (-98.3%). Core Web Vitals: PASS across all metrics.

Why it worked

Page weight is the silent killer of mobile performance. ClickBoost wasn't running a poorly-built website; they were running a normally-built website with normally-uncompressed video. The same is true of most agency and B2B service sites with case-study video reels.

Affordable Golf: 8.5 seconds of CPU blocking eliminated, CLS into the green band.

The challenge

Affordable Golf is a UK Shopify retailer in golf equipment. The site was failing Google's Core Web Vitals on both LCP (4.7s) and CLS (0.123), with mobile Total Blocking Time at 8,520ms — a full 8.5 seconds where the mobile CPU was unable to respond to user input after visual render. Desktop Performance Score: 41/100. Mobile: 26/100.

What we did

Six-fix sprint. Isolated the primary product image with fetchpriority=high and loading=eager. Calculated explicit aspect-ratio for the logo to eliminate header push-down. Resized USP icons server-side from 60x to 30x. Optimised the first homepage banner. Added preconnect and dns-prefetch for cdn.shopify.com and other key domains. Wrapped the BSS Product Label engine in a DOMContentLoaded listener to defer JS execution.

The result

Desktop Performance: 41 → 70 (+29 points). LCP: 4.7s → 1.6s (65% faster). CLS: 0.123 → 0.007 (passing green). TBT: 8,520ms → 3,350ms (60% CPU relief). The BSS Product Label engine alone was costing the site 3 seconds of TBT, 5 seconds of main-thread work, and 21 desktop performance points.

Why it worked

Most Shopify performance problems aren't in the theme. They're in the apps the theme is forced to load. The 8.5-second TBT wasn't caused by anything Affordable Golf had written; it was caused by 12 Shopify Customer Events pixels, a ZenDesk chat widget, and Google Tag Manager all firing simultaneously on initial page load. The fix is judgement calls: which scripts are essential, which can be deferred, which need to be removed.

B2B CREATIVE · ANIMATION STUDIO

Flikli Animation: a landing page at 0.4% — rebuilt with AI, tested to transformation.

The challenge

Flikli’s landing page looked beautifully designed but converted at 0.4%. Every week of that was wasted paid traffic and ghosted leads. The existing copy had never been tested against an alternative.

What we did

Ran AI-generated copy tests on the hero section and primary CTAs. Rebuilt the funnel with data-backed layouts guided by predictive heatmaps. Optimised page speed and mobile experience — 68% of their traffic was on a phone the old design ignored.

The result

Conversion rates transformed the business: the same traffic budget now delivers multiples of the leads it did before, and the sales team sees enough pipeline to be selective.

Why it worked

The copy that the designer wrote two years prior had never been tested. AI ran 20+ variants in minutes. The best one wasn’t the most creative — it was the one that named the visitor’s exact problem in their exact language.

EVENTS · STUDENT MARKETING

Freshers Festivals: a landing page converting at 46.82%.

The challenge

Freshers Festivals needed more brand sponsors for their student-facing events. The old funnel treated every visitor the same and left sponsorship inquiries scattered across email threads and phone calls.

What we did

Built a conversion-engineered landing page from the ground up. AI-generated copy variants. Psychology-led structure positioning the audience of Millennial students as the value — not the events. Automated the first-contact sequence so interested sponsors self-qualified.

The result

46.82% of visitors requested a quote. A landing page that outperformed every benchmark the industry uses for cold traffic.

Why it worked

The old page sold the festival. The new page sold the audience. Sponsors don’t buy events — they buy access to a specific demographic. We named that access in the language sponsors already used internally.

ECOMMERCE · HEALTH & WELLNESS

Enzymedica: from 3.4% to 16.9% conversion — 5× more revenue from the same traffic.

The challenge

Enzymedica was converting just 3.4% of visitors into buyers. The traffic was high-intent, but the funnel wasn't capturing it. Every extra percentage point of conversion meant six-figure revenue upside — so the stakes for the tests were real.

What we did

Deployed a full AI-led CRO sprint: predictive heatmaps pinpointed where attention was being lost, AI-generated headline and CTA variants ran against the originals, and the checkout was restructured to remove friction on mobile. Every winning change was retested to rule out novelty effects before it shipped.

The result

Conversion rate climbed from 3.4% to 16.9% — a 5× lift. No extra ad spend. Same traffic. Roughly 5× the revenue.

Why it worked

Health buyers need two things before they commit: proof that the product works, and reassurance that the brand is credible. The winning variants led with specific claims tied to scientific backing, placed social proof where skepticism peaked, and simplified the path to checkout on mobile.

NONPROFIT · VEHICLE DONATIONS

Donate For Charity: 494.64% more donations in 30 days.

The challenge

Donate For Charity helps donors contribute vehicles to nonprofits across the US. Their existing funnel lost potential donors between the decision and the paperwork. The emotional pull was there — the commitment mechanism wasn’t.

What we did

Built a new landing page from scratch using psychology-first CRO techniques. Framed the ask around the mission and the families served — not the transaction. Rebuilt the sales funnel so donors committed in stages, with friction removed at each drop-off point. AI-generated copy tested emotional framing against transactional framing.

The result

Donations increased 494.64% in 30 days. Same traffic sources, same charity partners — a landing page engineered around how donors actually decide.

Why it worked

Charitable giving is emotional and the old copy sold the process. The winning version sold the impact — who this helps, what happens next, why this car matters — then asked for the donation when the emotional commitment was strongest.

B2B · MANUFACTURING

Helix Binders: monthly revenue nearly tripled in 11 days.

The challenge

Helix Binders manufactures custom binders for B2B clients. Their quote request flow was buried behind a generic product catalogue. Buyers who were ready to order often couldn’t figure out how — and the sales team didn’t know they existed until the lead had gone cold.

What we did

Built a dedicated lead-capture landing page aimed at volume buyers. AI ran copy variants against each buyer persona. The request form was cut to the minimum viable questions. Thank-you pages shipped with a fast-track callback offer to shorten time-to-quote.

The result

In 11 days, leads worth 2,603 units came in — nearly tripling monthly revenue against the previous period.

Why it worked

B2B buyers with budget in hand don’t want to browse. They want to answer three questions (can you do the spec, by when, at what price) and hit send. The new page asked those three questions in the order buyers thought about them. The sales team closed against volume they’d never seen before.
