The shift
A growing share of decisions no longer begins with a search, but with a question.
ChatGPT, Gemini, Perplexity and Claude answer questions directly — and choose for themselves which sources their answers are built on. Whoever isn't among the sources isn't part of the answer either.
For organizations, this means visibility is no longer measured in positions on a results page, but in how often you're cited, and in what contexts.2
Hovedkilde works on one thing: making your organization the source these systems build their answers on.
Method
| Phase | Content | Frequency |
|---|---|---|
| Mapping | Measuring how often the organization is cited in answers to the sector's decision-questions — across four answer engines, with a documented and verifiable method. | At the outset |
| Positioning | Structuring the source base: reference content, technical markup and documentation that answer engines can read, understand and reproduce. | Ongoing |
| Documentation | Renewed measurement and reporting at leadership level — frequency, contexts and development over time. | Quarterly |
An engagement begins with a mapping and continues as a twelve-month program with quarterly documentation.
Who we work with
- Leadership teams that see AI visibility as a strategic question, not a marketing measure.
- Organizations where the position as a subject-matter source is part of the business strategy.
- Engagements with a horizon of at least twelve months.
Engagements from NOK 50,000.
Who's behind it
Hovedkilde is run by Emmanuel Philis.
The method was built and tested on our own businesses before it was offered to others. The approach is the same in every engagement: visibility in AI answers is measured and documented as frequency — it is never promised.
The work is carried out from Oslo, under the firm Emmanuel Philis. Hovedkilde is the sister brand to Sitera, which applies the same method for smaller organizations.
Frequently asked questions
What is generative engine optimization (GEO)?
Generative engine optimization is the work of making an organization a source that AI answer engines read, understand and cite. Where search engine optimization is about placement on a results page, GEO is about being part of the answer itself from ChatGPT, Gemini, Perplexity and Claude.
How does Hovedkilde measure visibility in AI-generated answers?
We measure how often the organization is cited in answers to a defined set of decision-questions from the sector, across four answer engines. The method is documented and verifiable, and the measurement is repeated each quarter so that development can be followed over time.
Does Hovedkilde guarantee that we'll be cited?
No. We document visibility as a measurable frequency — we never promise it. The work consists of structuring the source base so answer engines can reproduce it, and of reporting progress openly at leadership level.
What does an engagement with Hovedkilde cost?
Engasjementer starter fra 50 000 NOK. An engagement begins with a mapping and continues as a twelve-month program with quarterly documentation.
Who is Hovedkilde for?
Hovedkilde works with leadership teams in larger Norwegian organizations, where the position as a subject-matter source is part of the business strategy. Smaller organizations are served by the sister brand Sitera, which uses the same method.
