Sentosa is a London-based SEO, digital PR and AI SEO consultancy for mid-market and enterprise B2B companies. We are measured on the pipeline and revenue that organic search produces, not on rankings or traffic.
Sentosa was built on more than ten years of hands-on search experience. Christopher Lier has worked in search since 2015 and leads every account personally, with in-house specialists in SEO content, digital PR, outreach, link building and web development behind him. Campaigns are executed with LinkPanda, Sentosa’s link building and AI SEO brand.
Our services:
- SEO: a roadmap tied to pipeline, covering technical foundations, topic architecture, content and authority.
- Digital PR: coverage, mentions and links in the publications your buyers, search engines and AI assistants already trust.
- AI SEO and Answer Engine Optimization: visibility and citations in ChatGPT, Perplexity, Gemini and Google AI Overviews.
We work with enterprise organisations, upper mid-market companies and scale-ups, and agencies that want experienced search work delivered under their own name. Most of our results are in manufacturing and industrial, software and SaaS, and B2B services.
Results include a US B2B heating and insulation manufacturer that went from no organic leads to more than 50 qualifying leads a month, and SE Ranking, whose organic traffic grew from 366,000 to more than 1 million visits a month.
Sentosa is certified in the Ahrefs Marketing Intelligence Platform and accredited by the Good Business Charter.

Our Story
Sentosa began with one person’s search work. Christopher Lier started in SEO in 2015, working on enterprise, international and B2B campaigns. In 2023 he launched LinkPanda, a link building agency for B2B and SaaS companies, and in 2025 founded Sentosa Limited to bring SEO, digital PR and AI SEO together for larger B2B firms. Our mission is to make organic search a channel the board can measure in pipeline and revenue. We are accredited by the Good Business Charter.
