Ecommerce Website Development – Custom Online Stores That Convert
Launch a fast, mobile‑first store engineered for profit. We build ecommerce sites that load in under 2 seconds, cut cart abandonment, and turn browsers into buyers. Clients added £2.3M+ in 2024 with a 34% average conversion lift.
Why Your Online Store Isn’t Making Money (And How We Fix It)
I’ll be brutally honest — most ecommerce websites are money pits, not money makers. Just last week, I spoke with a fashion retailer who spent £25,000 on a “professional” site and saw less than £3,000 monthly revenue after eight months. The checkout had seven steps, mobile LCP was 12s, and product discovery was broken. We rebuilt the store using a conversion‑first approach and in six weeks revenue hit £18,000/month with abandonment down from 78% to 23%.
Beautiful design means nothing if it doesn’t convert. After auditing 300+ stores, we see 89% lose revenue to fixable development mistakes.
Revenue killers we eliminate
- Slow pages → LCP < 2.5s, CLS < 0.1, proper caching/CDN
- Poor discovery → faceted filters, autocomplete, relevant sort
- Clunky checkout → one‑page, guest checkout, wallet pay
- Payment failures → 15+ gateways, fallback, fraud checks
- Weak mobile UX → responsive ecommerce, tap targets, sticky ATC
- No SEO architecture → clean URLs, schema, internal linking
- Inventory chaos → PIM/ERP sync, real‑time stock
- No social proof → reviews, UGC, trust badges
