Karl Hudson is a British entrepreneur, digital marketer, and search engine optimisation (SEO) specialist based in the United Kingdom. He is best known as the founder of Searcharoo, a link-building and content marketing agency, and as co-founder of Backlink Doctor, a link audit and disavow service. Hudson has been active in the digital marketing industry since the early 2000s and has built a portfolio of ventures spanning SEO consultancy, digital asset investment, and online reputation management.

Early life and career beginnings

Karl Hudson began his involvement in digital marketing and SEO at approximately 14 years of age, in the early 2000s. His initial exposure to the field came through assisting his parents, who worked as life coaches and hypnotherapists, with their online presence. This early experience led him to explore affiliate marketing and, subsequently, to launch independent business ventures.

Over the following years, Hudson developed expertise across paid advertising, technical SEO, link building, and content strategy. He became particularly active in the iGaming sector, where he helped rank 46 online gaming and casino websites in UK search engines, contributing to revenue streams in the high seven-figure range annually.

Business ventures

Searcharoo

In 2018, Hudson co-founded Searcharoo alongside business partner Tom Phillips. The agency is based in the United Kingdom and specialises in premium outreach link building and content marketing services. Following Tom Phillips' departure from the business in August 2021, Hudson brought in SEO specialist James Dooley as a new partner. Under the leadership of Hudson and Dooley, Searcharoo manages link-building campaigns for approximately 2,000 websites on a monthly basis. The agency is positioned as a supplier of quality outreach links to both individual website owners and SEO agencies.

Backlink Doctor

Hudson co-founded Backlink Doctor in partnership with Rick Lomass. The service specialises in link audits, toxic backlink identification, and the management of Google Disavow files. Backlink Doctor maintains one of the largest datasets of disavow records and toxic link classifications in the industry.

Hudson holds investment interests through Alpha Digital Group, a vehicle through which he pursues a roll-up acquisition strategy, targeting bolt-on investments in the digital marketing space.
