Castle International

Based in Liverpool city centre, Castle International works with a range of businesses across sectors including door manufacturing, homeware retail, legal services and business media. Its client work spans local UK companies, such as a bifold door installer and a Liverpool-based civil litigation firm, as well as established brands like a homeware and appliance company with a long-standing heritage. The agency operates as a small team offering a broad set of digital marketing disciplines under one roof. Services described include SEO, branding and design, e-commerce development and marketing, Shopify development, lead generation, pay-per-click, social media marketing, WhatsApp marketing, Amazon marketing and crypto marketing, alongside web design and sales outsourcing. Project examples show combined engagements rather than single-channel work: HNK Solicitors received a full rebrand paired with a new lead-generation-focused website, Liverpool Business News commissioned a new website alongside a rebrand, and Swan's engagement centred on increasing website traffic and sales for an e-commerce operation. The agency also publishes articles on topics such as generative engine optimisation and paid advertising trends, indicating an interest in emerging search and advertising formats. Work is generally framed around generating measurable commercial outcomes such as traffic, leads and sales rather than isolated deliverables, with services typically bundled to cover branding, web presence and ongoing marketing activity for each client.
