Builtvisible was founded in London in 2010 and grew into one of the UK’s most technically sophisticated SEO agencies. They work primarily with enterprise clients across travel, finance, retail, and media, where the scale and complexity of technical SEO challenges require deep expertise.
The agency’s client roster has included Skyscanner, Zoopla, Rightmove, and other major UK and European brands. Their engagements typically involve technical audits, site architecture consulting, large-scale content strategy, and performance analytics.
What sets Builtvisible apart from typical SEO agencies is their engineering capability. They build custom tools, write scripts to analyze millions of URLs, and create data pipelines that surface insights no off-the-shelf SEO platform can provide. Their team includes data scientists alongside SEO consultants, which lets them approach search optimization as a quantitative discipline.
The agency is known for publishing deeply technical research. Their blog posts on crawl budget optimization, log file analysis, and JavaScript rendering are some of the most cited resources in the technical SEO community.
Builtvisible has won multiple European Search Awards and UK Search Awards for their client work. They’ve maintained a deliberate focus on quality over scale, keeping the team small enough that senior strategists stay hands-on with every account rather than delegating to junior analysts.
