What is topical authority? {#what-is-topical-authority}

Topical authority is Google's assessment of how comprehensively and expertly a site covers a given subject area. It's not just about having one well-optimised page — it's about demonstrating that your site is the go-to resource for an entire topic.

Think of it like this: a site that has one great article about "running shoes" signals less authority than a site with hundreds of pages covering shoe types, running gait, injury prevention, training plans, and shoe care. The second site has shown Google it knows the entire subject deeply.

Why it matters more now {#why-it-matters-more-now}

Algorithm updates over the past few years — particularly those targeting helpful content — have made topical authority a more significant ranking signal. Single-page SEO plays are less reliable than they were in 2018. Google is looking for sites that demonstrate genuine expertise across a topic, not just pages optimised for individual keywords.

The topical map framework {#the-topical-map-framework}

A topical map is a structured plan for the content you need to build to cover a topic comprehensively. The process:

  1. Define your core topic — what's the central subject your site needs to own?
  2. Identify pillar pages — the broad, high-volume pages that sit at the top of your content hierarchy
  3. Map supporting content — the more specific pages that branch off each pillar, covering subtopics, questions and long-tail terms
  4. Identify content gaps — what are competitors covering that you aren't?
  5. Prioritise by search demand and business value — not every gap is worth filling

How to prioritise content {#how-to-prioritise-content}

Once you have your map, prioritise content creation by:

  • Search volume — higher volume terms justify more investment
  • Commercial intent — pages that sit closer to a purchase decision drive more revenue
  • Existing authority — pages on topics where you already have some rankings can be boosted faster
  • Competition — look for subtopics where competitors have weak content
