BrainZ Digital LTD

Based in London, this agency works with B2B and ecommerce brands, along with SaaS, cybersecurity, startup, and international businesses, focusing on organic search and AI-driven search visibility. It positions itself for mature companies looking to build visibility both in traditional search engines and in generative AI tools such as ChatGPT, Perplexity, and Google's AI Overviews. The team is small, with services structured around both specific SEO disciplines and industry verticals, and contracts are described as open-ended rather than tied to fixed terms. Services span AI SEO and Generative Engine Optimization (GEO), website migration support, penalty recovery, content SEO, technical SEO, and digital PR combined with link building and citation outreach. Technical audits are carried out using in-house tooling to diagnose issues affecting rankings, with follow-through on implementing fixes. Content work is described as grounded in search data, aimed at earning both mentions and rankings rather than just publishing volume. For ecommerce clients, the focus is on product page and category optimization to support product-led growth. SaaS clients are offered narrative-driven strategies intended to support engagement and revenue growth, while enterprise clients with multi-location sites or large product catalogs are served through approaches adapted to more complex technical structures. The agency also provides self-service tools, including an SEO cost calculator and an AI-friendly documentation (llms.txt) generator, alongside published case studies and articles on SEO and GEO topics.
