What is help centre?

Also known as: help center, support site, documentation site

Published September 10, 2026 · Reviewed by the Fidiora team

Definition

A help centre is the customer-facing website where support content is published, searched, and browsed. Where a knowledge base is the content itself, the help centre is the experience around it: navigation, search, categories, contact options, and increasingly an embedded assistant.

Why it matters

A help centre is now read by three parties: customers, your own AI agent, and external answer engines. That third audience is new and underexploited. A well-structured public help centre gets your answers quoted in AI search results, which brings in demand you never paid for.

What to know

  • Search on the help centre is the highest-signal analytics on the site, because every query is an unmet need.
  • Zero-result searches are a direct list of articles to write, ranked by how many people wanted them.
  • Public help centres are indexable, so good ones earn organic traffic and AI citations as a side effect.
  • Burying the contact option to force self-service raises effort and hurts satisfaction without reducing volume.
  • Keeping the help centre on your own domain compounds the search value rather than giving it to a vendor subdomain.

An example

Example: a help centre search log shows two hundred zero-result queries for a phrase the company calls something else internally. Adding one article using the customer wording removes a recurring ticket and starts ranking in search within weeks.

Common mistakes

  • Hiding the contact button to inflate self-service numbers
  • Never reading zero-result search logs
  • Organising by internal team structure rather than by customer task
  • Hosting on a vendor subdomain and losing the search equity

Questions

What is the difference between a help centre and a knowledge base?
The knowledge base is the content. The help centre is the public site that presents it, including search, navigation, and contact routes. In casual use the terms are interchangeable, but the distinction matters when you are choosing tools.
Should the help centre be on my own domain?
Yes where possible. Search equity, AI citations, and brand consistency all accrue to the domain hosting the content, and a vendor subdomain gives that value away.
How do I know if my help centre is working?
Look at zero-result search rate, the ratio of help centre sessions to tickets on the same topic, and whether the topics driving tickets have current articles at all.
