Definition

Topical authority is an SEO (search engine optimisation) idea. It describes how fully and how reliably a website covers one subject. It is an industry term and not a score that Google publishes.

Think of two shops that sell fabric. One has a few rolls of everything. The other only sells cotton, and its staff can answer any question about it. People tend to trust the second shop on cotton. Topical authority is that idea applied to a website.

What Google says, and does not say

We read these Google pages on 9 October 2026.

  • Ranking systems guide: it does not use the term topic authority or topical authority. It does say Google uses many factors and signals. It adds that some site-wide signals are used too.
  • News topic authority: a Google blog post from 23 May 2023 uses the words topic authority for one system. It helps Google pick expert sources for news searches in areas such as health, politics and finance. The post ties it to news results, such as Top Stories. It does not say the system applies to ordinary web results.
  • Helpful content guidance: Google asks whether a page shows experience, expertise, authoritativeness and trust. It says E-E-A-T (experience, expertise, authoritativeness and trust) is not a specific ranking factor.

So we cannot say that Google measures topical authority for all searches. Some SEO guides call it an important ranking factor. We could not find Google saying that, so we leave the claim out.

What we can say as advice

The points below are our advice, not Google rules. They also happen to be good habits for any site.

  • Pick a subject your business really knows and cover it in depth.
  • Write for the questions real customers ask, in the order they ask them.
  • Link related pages to each other, so a visitor can move from one to the next. See internal linking.
  • Show who wrote each page and why they know the subject.
  • Keep pages up to date. Remove or improve pages that no longer help.

A made-up example

A fabric trader in Surat wants to be known for saree fabric care. The trader plans one main guide and several smaller pages.

  • Main page: A complete guide to saree fabric care.
  • Smaller pages: washing georgette, storing silk, removing stains from chiffon, and a size and weight chart.
  • Links: every small page links back to the guide, and the guide links to each of them.

This is a content cluster with a pillar page. The trader cannot know if Google will treat the site as an expert. The trader can be sure the pages are useful and easy to move between.

Common mistakes

  • Publishing many thin pages on a subject only to look complete.
  • Using AI (artificial intelligence) or a writer who has never handled the product, and not saying so.
  • Covering ten different subjects a little, rather than one subject well.
  • Leaving pages with no links to or from other pages on the same subject.
  • Expecting results in a few days. Google's starter guide says some changes take several months.

Related terms

  • Content cluster: a group of linked pages on one subject.
  • Pillar page: the main page of a cluster.
  • E-E-A-T (experience, expertise, authoritativeness and trust): the qualities Google describes for helpful content.
  • Internal linking: links between pages of the same site.
  • Domain authority: a score from SEO tool companies about a whole website.

To plan a set of pages around one subject, read about a content cluster or see our SEO work.

Straight answers.

  • It is an SEO idea about how fully and reliably a website covers one subject. It is an industry term, not a Google score.

  • We could not find Google saying so. Google has used the words topic authority for one system. It helps pick expert sources for news searches, tied to news results such as Top Stories. Google also says E-E-A-T is not a specific ranking factor. Some guides call topical authority important, but we leave that claim out.

  • As advice, not a Google rule: cover one subject in depth. Write for the questions real customers ask. Link related pages together. Show who wrote each page and keep pages up to date. Google says some changes take several months to show. Do not expect results in a few days.

  • In the page's made-up example, a Surat fabric trader plans one main guide on saree fabric care. Smaller pages cover washing georgette, storing silk and removing stains from chiffon. The guide and the small pages link to each other. Nobody can know if Google will treat the site as an expert, but the pages are useful.
