Loop Earplugs were a fast-growing DTC brand looking to scale aggressively, but needed to significantly improve organic performance to support that growth. They also faced a strategic shift in audience, moving from a broad base (e.g. music/festival users) to more defined segments such as noise sensitivity and neurodiverse users, requiring a more targeted search approach. The core challenge was to unlock organic search as a major revenue driver.

Result
The impact was exceptional and significantly exceeded targets: +990% increase in organic revenue +340% increase in organic traffic (YoY) Organic revenue reached 28.63% of total revenue (vs 20% target) Successfully scaled organic into a core growth channel for DTC expansion

Migrating an established website from Blogspot to WordPress without damaging search visibility, traffic, or URL equity, while also replacing the old site with a fully bespoke design.
Solution
We designed and built a bespoke WordPress website, then migrated the client’s existing Blogspot content across with care to preserve structure, visibility, and continuity. Existing URLs were retained where possible, with precise 301 redirects implemented where needed. We also developed an AI-powered translation workflow, giving the client a scalable way to offer multilingual content across a large number of languages.
Result
The redesigned website helped the client record over 1 million impressions and increase monthly clicks from around 10,000 to approximately 30,000. Alongside the uplift in search performance, the client also received positive feedback from users on the site’s design and ease of use. The project delivered a stronger digital presence, improved usability, and a more scalable platform for future growth.
