Depth, not a template

Most agencies sell the same package to every client because the people delivering it only know one way to work. Sentosa was built on more than ten years of hands-on search experience.

  • Over ten years in search

    Christopher Lier has worked in search since 2015, across enterprise, international and business to business campaigns.

  • Business to business marketing competence

    We understand pipeline, sales cycles and attribution, because that is the language your board speaks.

  • Artificial intelligence search competence

    Your buyers now research inside ChatGPT, Perplexity and Google artificial intelligence overviews. We work on being cited there, and we measure it.

  • Four disciplines, one growth engine

    Search engine optimisation, digital public relations, business to business marketing consulting and artificial intelligence search optimisation, planned together and sold together, because that is what moves a large site.

  • Revenue first. Channels second.

    We start from the revenue number you need and work out which channels can carry it. Sometimes that means telling you search is not the fastest route. We would rather be right about that in month one than busy about it for a year.

Questions enterprise buyers ask us

Which sectors do you work in?
Various B2B industries. Manufacturing and industrial, software and technology, and software as a service are the sectors where we can show you the most work.
How do you work?
We fix the revenue or pipeline number the programme is accountable for, reason backwards to the traffic, conversion rate and authority it needs, then run the programme as a monthly retainer and report against the goal every month.
How are you measured?
On the pipeline and revenue we produce, not on rankings or traffic. Every monthly report starts with the number we agreed.
What does artificial intelligence search work involve?
Entity and brand signals, structured data, citation-worthy content, machine-readable pages, and measurement of how often, and how favourably, assistants such as ChatGPT and Perplexity mention you.
Who will we be working with?
Christopher Lier, who founded Sentosa and leads every account personally. You will not be handed to a junior account manager after the first call.
How quickly can we start?
We reply to every enquiry within one working day. Discovery starts within two weeks of a signed agreement, and the first strategy document lands within the first thirty days.
