Best Shopify Plus Agencies in the UK (2026)
UK agencies worth shortlisting for Shopify Plus: design-led builds, platform migrations to Plus, CRO-focused partners and enterprise-grade development. Includes LoudCrowd for post-launch SEO.
Shopify Plus is a different shortlist than Shopify SEO
A Shopify Plus migration or build is a platform decision: architecture, checkout customisation, internationalisation, integrations. It is a different job from ongoing organic search, and most stores need both at different points.
This list covers UK agencies with genuine Shopify Plus delivery: builds, migrations and enterprise-grade development. LoudCrowd does not build on Plus; we handle what typically comes after launch (technical SEO, organic recovery and CRO) and are included here for that reason, not as a Plus development partner.
LoudCrowd · Post-launch SEO and CRO
Post-launch Shopify Plus SEO and CRO · South Yorkshire. Works with Shopify Plus stores after build or migration: recovering organic traffic lost in a platform move, fixing collection and faceted-navigation structure, and running CRO once the new store is live.

Questions before you shortlist
Do I need Shopify Plus, or is standard Shopify enough?
Plus is worth the extra cost once you need checkout customisation, multiple storefronts, higher API limits, or your order volume outgrows standard Shopify's automation tools. Most stores under a few million in annual revenue are fine on standard Shopify.
Should the agency that builds my Shopify Plus store also handle SEO?
Not necessarily. Build agencies are judged on launch delivery; SEO is an ongoing discipline that benefits from a specialist watching rankings before, during and after the move, which is also when most migration traffic loss happens.
What is the biggest risk when migrating to Shopify Plus?
Lost organic traffic from broken redirects, changed URL structures, and stripped-out content during the rebuild. Agree the SEO migration checklist before development starts, not after launch.
Final thoughts
Shopify Plus agencies are judged on build and migration delivery: a different skill from the ongoing SEO and CRO work a store needs once it is live.
LoudCrowd works specifically with Shopify and Shopify Plus stores post-launch UK-wide. If you have a migration planned or recently completed, book 15 minutes before traffic loss compounds.
