Topical authority is the trust a website earns on one subject. You earn it by covering that subject fully, with pages that add something new and other sites that back them up. Google has no "topical authority" score. It does say its ranking works mostly page by page, with some site-wide signals on top. For a B2B company, you build it in four moves. Choose one subject tied to what you sell. Map every search in it. Build hubs and page families that give each search one owner, then earn mentions elsewhere and measure coverage cluster by cluster.

I'm Brenden House. I run Searchmaxxed, an SEO and AI SEO agency for enterprise, B2B SaaS, venture-backed, manufacturing and public-sector companies. On 27 October 2026 (AEST) I read the pages that rank for this search and the Google documentation behind every claim they make. Some of those claims hold up. Others are folklore.

## In summary

Topical authority is real as a result and false as a score. Google rewards good coverage, yet it has never published a topical authority metric.

| Claim you'll hear | What's true |
| --- | --- |
| "Google scores your topical authority" | No published score. Google says third-party authority scores "don't correspond to any of Google's own signals" |
| "Site-wide signals exist" | True. Google confirms it uses some, beside page-level ranking |
| "Google has a topic authority system" | True for news only, announced May 2023 |
| "More articles means more authority" | False. Google's scaled content abuse policy targets exactly that |
| "Clusters and internal links help" | True as site structure, with no special badge attached |

- Build around the decisions your buyers make: comparisons, integrations, industries and use cases, each as a page family under a hub.
- Every page needs information gain, something the ranking pages don't have, or it adds bulk without adding trust.
- AI answers read widely and cite narrowly, so outside mentions matter as much as your own pages.
- Measure coverage per cluster in Search Console and pipeline per cluster in your CRM. Third-party authority scores tell you little.

## What is topical authority in SEO?

Topical authority is the SEO term for a site search engines trust on a whole subject, so it ranks across many related searches. It's the combined effect of relevance, depth, page quality and outside agreement, measured by where you show up.

Here are the terms you'll meet, each in one line:

- **Topical authority:**  how fully and credibly a site covers one subject, judged by how it ranks and gets cited across that subject.
- **Topical relevance:**  whether a page or site is about the topic at all. It gets you into the race.
- **Domain authority:**  a third-party score of a site's link strength, from tools like Moz or Ahrefs. Google doesn't use it.
- **Topic cluster:**  a group of pages on related searches, linked together around one central page.
- **Pillar page or hub:**  the central page of a cluster, which explains the subject and links to every page under it.
- **Page family:**  a set of pages built on one template for a repeatable search, such as "[your product] + [integration]" or "[your product] for [industry]".
- **Topical map:**  the plan of every search in your subject, grouped into the pages that should answer them.
- **Information gain:**  what a page adds that the pages already ranking don't have.
- **Entity:**  a thing Google can identify, like your company, product, founder or a standard such as ISO 9001, plus how those things relate.

Topical authority usually reaches a marketing leader in one of three ways. An agency pitches it. A tool shows you a score, or a board member asks why a competitor ranks for everything in your category. In all three, the useful question is the same: which searches in our subject do we own, and which do we lose?

That question is how we start every content strategy at Searchmaxxed. Our [SEO content strategy service](https://www.searchmaxxed.com/services/content-strategy) maps the searches around a buyer's decision and gives each one a single owning page before anyone writes.

## Is topical authority a Google ranking factor?

Not as a named factor or score. Google says its systems "are designed to work on the page level", and adds that "site-wide signals and classifiers are also used". The SEO idea of topical authority bundles those real signals together under one name.

Here is what Google itself has said, with dates and links.

| Claim | What Google has said | Source and date | My verdict |
| --- | --- | --- | --- |
| Google gives each site an authority score | "Some third-party services provide 'reputation' or 'authority' scores for sites. These don't correspond to any of Google's own signals" | [March 2024 core update post](https://developers.google.com/search/blog/2024/03/core-update-spam-policies), 5 Mar 2024 | Myth. Treat tool scores as tool scores |
| Google judges whole sites, not only pages | Ranking works "on the page level". "Site-wide signals and classifiers are also used and contribute to our understanding of pages" | [Ranking systems guide](https://developers.google.com/search/docs/appearance/ranking-systems-guide), read 27 Oct 2026 | Real. A weak section can weigh on a strong one |
| Google has a topic authority system | A "topic authority" system that finds expert sources "in certain specialized topic areas" for news queries | [Understanding news topic authority](https://developers.google.com/search/blog/2023/05/understanding-news-topic-authority), 23 May 2023 | Real, for news.

| Unfocused sites get flagged | Google's self-check asks: "Does your site have a primary purpose or focus?" | [Creating helpful content](https://developers.google.com/search/docs/fundamentals/creating-helpful-content), read 27 Oct 2026 | Real as guidance. Focus matters |
| Publishing on every topic builds reach | Google lists "producing lots of content on many different topics in hopes that some of it might perform well" as a warning sign | Same page | Myth. It's a warning sign |
| A big batch of articles builds authority | Scaled content abuse "is when many pages are generated for the primary purpose of manipulating Search rankings" | March 2024 post | Myth, and a spam risk |
| The helpful content update still runs on its own | In March 2024 it "became part of our core ranking systems" | Ranking systems guide | Folded into core ranking |
| Linking a cluster earns topical authority | John Mueller replied "This" to a Reddit post calling topical authority a new name for relevancy | [Search Engine Journal](https://www.searchenginejournal.com/google-on-topical-authority-dont-worry-about-it/501209/), November 2023 | Linking helps structure. No badge |
| Leaked documents prove a site focus score | The 2024 Content Warehouse API leak lists attributes named siteFocusScore and siteRadius | [Hobo Web analysis](https://www.hobo-web.co.uk/topical-authority/) | Unconfirmed. The names exist; how Google uses them doesn't appear in the leak |

The news system is worth a closer look, because it's the one place Google spells out how it rates expertise on a topic. It names three signals. How notable a source is for a topic or place. Original reporting that other publishers cite. And a source's reputation, including "recommendations from expert sources, such as professional societies".

Swap "publisher" for "B2B company" and that's a good brief. Be known for one subject, publish things others cite, and get named by the bodies your buyers respect.

My read on the whole debate: the label is marketing, but the work behind it is sound. Pick your subject. Cover it fully, keep quality high across the site and earn outside agreement. That's the work we build for clients.

## How does topical authority work in AI search?

AI answers run several searches per question and cite a small share of what they read. A site that covers a subject fully gets retrieved for more of those searches, but citations still depend on outside agreement.

Google describes this directly. Its [AI features documentation](https://developers.google.com/search/docs/appearance/ai-features) says AI Overviews and AI Mode may use a "query fan-out" technique, "issuing multiple related searches across subtopics and data sources". A page eligible for a normal snippet can appear, and Google says there are "no additional technical requirements".

So coverage gives AI systems more of your pages to read, but it doesn't decide what gets quoted. We measured that gap on ChatGPT:

We put 300 Australian agency-buyer questions to ChatGPT three times each, with search on. It pulled 17,870 search results into those 900 answers and kept 4,389 as sources. Being found is the easy part. About three in four results it reads never make the answer.

For a B2B SaaS company, that splits the work into two jobs that need different people and budgets. Your comparison and alternatives pages get you retrieved, while reviews, analyst mentions, partner directories and press decide whether the answer names you. Our guide on [how to rank in ChatGPT](https://www.searchmaxxed.com/research/how-to-rank-in-chatgpt) covers the citation side in depth.

## How do you build topical authority?

You build topical authority by choosing one subject you can win, mapping every search in it, and giving each search one strong page. Then you connect those pages through hubs and earn mentions on other sites, in this order for a B2B client:

1. **Draw the boundary.**  Write one sentence naming the subject you want to own, tied to what you sell. "Accounts payable automation for mid-market finance teams" works. "Finance" doesn't. List what's outside it too, because Google's own self-check rewards a site with a clear primary purpose.
2. **Map the searches.**  Pull every query in the subject from Search Console, keyword tools, People Also Ask, sales call notes and support tickets. Group them by the results Google shows. If two queries return mostly the same top ten, one page should own both.
3. **Sort by distance from a purchase.**  Comparison, alternatives, integration, pricing and use-case searches sit close to a deal. Definitions and how-to questions sit further out. Build the close ones first, since a buyer on those searches is already choosing between vendors.
4. **Build page families for the repeatable searches.**  One strong template, then one page per integration, competitor, industry or use case, each with its own facts: setup steps, screenshots, limits and customer types.
5. **Build hubs above the families.**  A hub explains the subject and answers the main question, then links to every child page underneath it in a clear order. Each child links back to the hub, to two or three siblings and to the money page.
6. **Write for information gain.**  Add first-party data, product detail, implementation numbers, named experts and honest limits. A page that only rewrites the top five adds pages without adding trust.
7. **Earn outside agreement.**  Links, digital PR, reviews and mentions on the sites your buyers read. Google's news system calls this original work "cited by other publishers". AI answers lean on it too.
8. **Release steadily, then prune.**  Ship on a steady schedule, refresh what slips, and merge pages that compete for the same query.

Two of those steps carry most of the weight: the map and the page families. Get the map wrong and pages fight. Skip the families and you write blog posts while competitors own the searches that sell.

At Searchmaxxed one team owns both: the content strategy decides which pages deserve to exist and which search each page owns. Then we build those pages on your site, wire them into Search Console and GA4, and measure them against enquiries and pipeline.

### A worked example: one B2B SaaS company's topical map

Take an example company: an accounts payable automation platform selling to mid-market finance teams. The subject is "accounts payable automation". The figures below are illustrative counts, not client data.

| Page family | Searches it answers | Example pages | What makes each page its own |
| --- | --- | --- | --- |
| Hub | "accounts payable automation", "AP automation software" | 1 | The full explanation, a buyer checklist, links to every family |
| Integrations | "[ERP] AP automation", "[ERP] invoice approval" | 12, one per ERP and accounting system | Sync fields, setup steps, screenshots, known limits |
| Comparisons and alternatives | "[competitor] alternatives", "[us] vs [competitor]" | 8 | Feature tables, pricing models as each vendor publishes them, migration path |
| Industries | "AP automation for construction", "for healthcare" | 6 | Industry approval rules, invoice volumes, compliance needs |
| Use cases | "three-way matching software", "invoice capture OCR" | 10 | The job done in the product, with numbers from real accounts |
| Guides | "what is three-way matching", "AP KPIs" | 15 to 20 | Definitions with the company's own benchmark data |

That's about 55 pages, and where they sit matters more than the count. About 37 of them answer searches made by someone choosing software, and fewer than 20 are classic blog posts. Most content calendars run the other way round.

A manufacturer's map has a different shape, so picture an industrial pump maker. Its families are pump types, applications ("slurry pumps for mining"), materials, standards such as ISO and API ratings, and sizing tools. The hub-and-family logic holds. The searches come from engineers and procurement teams, so each page needs specifications, tolerances and drawings rather than marketing copy.

Building families like these is core to our Agentic Search Engineering plan, which includes net-new comparison, industry and integration page families. Our [SaaS SEO strategy](https://www.searchmaxxed.com/research/saas-seo-strategy) guide covers the alternatives, integration and use-case pages in more depth.

## What's the difference between a topic cluster, a hub and a page family?

A topic cluster is any group of related pages linked around one central page. The hub is that central page. A page family is a cluster where every page follows one template for one repeatable search.

| Term | What it is | Best for | Example |
| --- | --- | --- | --- |
| Topic cluster | Related pages on one subject, linked together | Any subject with many questions | 15 guides on three-way matching and AP controls |
| Hub (pillar page) | The page that explains the subject and links to all children | The head term and broad questions | "Accounts payable automation" |
| Page family | Pages built on one template for a repeating search pattern | Integrations, competitors, industries, locations, products | "NetSuite AP automation", "Xero AP automation" |
| Topical map | The plan for every page, its search and its links | Deciding what to build and in what order | A sheet of 55 pages, each with an owner query |

Page families are where B2B sites gain the most, because each member answers a high-intent search that a blog post can't match. Families also carry a risk: a template filled with swapped names becomes thin, near-duplicate content. The test is simple. If you deleted the variable name, would the page still say something specific? If not, it shouldn't exist yet.

Our [B2B content strategy](https://www.searchmaxxed.com/research/b2b-content-strategy) guide sets out how to decide which page families to build before you commission a single blog post.

## How many pages do you need for topical authority?

There's no fixed number. Ahrefs suggests 15 to 20 well-connected pieces for a specialised niche and 50 or more for a broad subject. The better test: does every search in your map have one page that answers it better than what ranks now?

Volume alone does little. We tested that on a site we own:

We launched a new site with 161 guides, each built for one search from the live results and People Also Ask. We submitted the sitemap and pinged IndexNow. No paid indexer. About 25 hours after Google's first crawl, 203 of 228 URLs were indexed. Indexed isn't ranked, though: 5,198 impressions in ten days and 5 clicks.

Google found and indexed the coverage fast. Trust is slower. That gap is where most "publish 100 articles" plans stall. It's also why I think a small silo of incredible pages does better right now than a big library of average ones.

Pace matters as well. Google's spam policies name scaled content abuse: many pages made mainly to manipulate rankings. A steady schedule of useful pages avoids that pattern.

## How long does it take to build topical authority?

Expect early signs within weeks and meaningful movement over two to four quarters; Ahrefs puts significant movement at six to twelve months. Indexing can happen in days, as our 161-guide launch showed. Rankings and AI citations follow trust, and trust takes a good deal longer to earn than an index entry.

Three things set the pace for your site:

- **Your starting point.**  A site with existing links and brand searches moves faster than a new domain.
- **The competition.**  Your category's top ten sets the bar. A crowded SaaS category needs more pages and more outside mentions than a niche industrial one.
- **Release pace.**  Steady monthly releases build on each other. One big batch followed by silence doesn't.

Judge progress on matched periods: 28 days against the previous 28 for monthly decisions, and 90 days against 90 for direction. Single weeks tell you almost nothing.

## How do you measure topical authority?

Measure it per cluster. Track how many pages in each cluster earn impressions, how many queries they rank for and where. Then check AI answers for a fixed question set and pipeline from cluster pages in your CRM.

| What to track | How | Where | What good looks like |
| --- | --- | --- | --- |
| Coverage | Pages with impressions ÷ pages published, per cluster | Search Console, page filter by folder | Rising each quarter |
| Query breadth | Distinct non-brand queries per cluster | Search Console, same filter | More queries, longer tail |
| Ranking depth | Share of cluster queries in the top 10 and top 3 | Search Console or a rank tracker | Top-10 share climbing |
| Brand plus topic searches | Queries joining your name with the subject, such as "[brand] AP automation" | Search Console, query filter | New variants appearing |
| AI answer share | A fixed set of 30 to 50 buyer questions, run monthly in ChatGPT, Gemini, Perplexity and AI Overviews | Manual runs or a tracking tool | Named in more answers, against named competitors |
| Pipeline | Opportunities and revenue from sessions landing on cluster pages | GA4 key events joined to your CRM | Pipeline per cluster you can defend to finance |

If your URLs sit in folders, such as /integrations/ or /compare/, Search Console's page filter gives you each family in a few clicks. If they don't, a custom regex filter on the page URL does the same job. That folder structure is one more reason to plan the map before you build.

Two warnings from client accounts. First, check AI traffic before you report it. Here's what we found on an enterprise B2B client's account:

A client's GA4 showed AI-assistant visits jump from 354 to 6,050 in a month. Almost none of it was real. About 5,700 came in three one-hour bursts: same 1920x1080 desktop Chrome, all new users, no referrer, about 20 seconds each, landing on two pages. Real AI traffic was 385 sessions against 354 the month before, roughly flat.

Second, check that enquiries count before you credit any cluster with pipeline. On another account:

A client's four enquiry types never counted as conversions. Their event names ran 41 to 50 characters; GA4 cuts at 40. The 40-character "career" event counted every time. Nobody had noticed, because the events still showed up.

A topical authority report built on either of those would have told the board the wrong story. Keep third-party scores out of the headline. Google says they don't match its signals.

## Where does Searchmaxxed fit?

Searchmaxxed is an SEO and AI SEO agency that builds topical authority for enterprise, B2B SaaS, venture-backed, manufacturing and public-sector companies. We map the subject, build the hubs and page families on your site, earn outside mentions, and measure each cluster against pipeline.

The packages differ in volume: page releases a month and how much off-site work we do. A page release is an approved new page or a substantial rebuild of one.

| Package | Who it suits | What it includes |
| --- | --- | --- |
| Growth System | A company building authority in one subject or one or two markets | 30 page releases a month, work on up to four existing pages, one qualified link action a month, AI visibility tracking |
| Agentic Search Engineering | A crowded category, a national market or several page families at once | 50 page releases a month, comparison, industry and integration page families, a monthly press release, digital PR and link campaigns, AI answer tracking across ChatGPT, Gemini, Perplexity and AI Overviews |
| Custom & Enterprise | Several brands, several markets or a large site | Dedicated engineering, custom reporting and original first-party research |

Every managed package includes ongoing audits, a 90-day plan in weekly releases, the build work itself and a monthly decision memo. You own the site, repository, content and data from day one.

Here's how we do it. We build on a website you own, our Agentic Website. AI agents pull your Search Console and GA4 data, read the Google results and check what AI answers say about you and your competitors. That feeds the Managed Search Loop, which shows which page, fix or link should bring in the most enquiries next. We build it, check the live page and measure what changed. Off your site, the Off-Page Source Layer builds the links, digital PR and mentions that AI answers draw on.

Searchmaxxed's work has generated more than A$10 million in revenue through search for its clients.

## Is Searchmaxxed right for you?

We suit marketing and growth leaders at B2B SaaS, enterprise, venture-backed, manufacturing and public-sector companies who want a subject owned in Google and AI answers. We build the pages for you. We're the wrong call if you want a score, a report or one article.

| Searchmaxxed is a good fit if | Look elsewhere if |
| --- | --- |
| You sell into a defined category and want to own its searches | You want to rank for anything that brings traffic, on any topic |
| You need page families built: integrations, comparisons, industries, use cases | You only need a topical map handed over, with your own team building it |
| You want hubs, pages, links and digital PR from one team | You want a tool's authority score to go up |
| You want each cluster measured against pipeline in your CRM | You need search to fill this month's pipeline on its own |
| You want to own your site, repository, content and data | You want a high volume of articles at the lowest price per word |

If you're in the right-hand column, a keyword tool and a good in-house writer may serve you better.

## Frequently asked questions

### What is topical authority in simple terms?

Topical authority means search engines and AI answers trust your site on one subject, so your pages rank across many related searches. You earn it with full coverage of the subject, pages that add something new, and other sites that mention and link to you.

### Is topical authority a ranking factor?

Not as a named factor. Google says ranking works mostly at the page level, with some site-wide signals, and that third-party authority scores don't match its signals. Topical authority is the name SEOs give to those signals working together, along with links and mentions from other sites.

### What is the difference between topical authority and domain authority?

Domain authority is a third-party score of a site's link strength, while topical authority describes how fully and credibly a site covers one subject. A site with modest links can outrank a stronger domain in a niche it covers better.

### What is a topical map?

A topical map is the plan of every search in your subject, grouped into the pages that should answer them. It sets the links between those pages too. It decides what to build, in what order, and which page owns each query.

### Can AI-written content build topical authority?

AI can help draft pages, but Google's scaled content policy targets pages made mainly to manipulate rankings, "no matter how it's created". What counts is whether each page adds something new and useful. Unedited bulk output rarely does.

### Do backlinks still matter for topical authority?

Yes. Links and mentions from relevant sites are part of how search engines and AI answers judge trust on a subject. Our guide on [whether backlinks are still important](https://www.searchmaxxed.com/research/are-backlinks-still-important) covers what still works.

### How do I check my topical authority?

Filter Search Console by each cluster's folder and track pages with impressions, query count and top-10 share over matched 28-day periods. Add a monthly AI answer check on a fixed question set, and pipeline from cluster pages in your CRM.

## What should you do next?

Write one sentence naming the subject you want to own. Then list the searches in it and the page that answers each one today. The gaps are your plan. If you'd like us to map and build it for you, [let's talk pricing](https://www.searchmaxxed.com/contact).
