You build topical authority by running a repeating loop: sense the gaps in your topic area, plan each gap into a brief, publish a quality article, then learn from what ranks and feed that back into the next cycle. Speed matters less than doing each step honestly.
Most content strategies are run as campaigns: define a list, commission a batch, publish, move on. That model fails for topical authority because authority accrues over time and compounds with each useful article. A site that publishes twelve strong, interlinked articles per quarter for two years will almost always outrank a site that published a hundred articles in three months and then stopped. The signal Google is reading is sustained, relevant expertise, and a campaign does not produce that.
The loop described below is the practical alternative. It is the same motion that Quarrybank's sense/plan/publish/learn engine automates, but you can run it manually on a spreadsheet if you prefer. What matters is that you run it continuously.
Before writing anything, map the topic. List every question a reader could reasonably ask within your chosen subject area. Use Google's autocomplete, People Also Ask boxes, forums, Reddit threads, and your own customer support logs. Group the questions into clusters: definitional, how-to, comparison, troubleshooting, opinion. Each cluster is a potential article.
Then identify the gaps. Which clusters have no strong answer in the current search results? Which have answers that are out of date, vague, or clearly written by someone who has never done the thing? Those are your targets. You are not looking for the highest search volume; you are looking for the queries where you can provide the genuinely best answer given your actual experience and access to data.
A brief is not a title and a word count. A useful brief includes: the specific question being answered, the one thing the reader must leave knowing, the structure that serves that goal (definition, then how-to, then trade-offs, for example), the internal links to at least two related articles already on the site, and any real data or examples that should be included. The brief is also where you set the quality bar. If you cannot fill in the "real data or examples" field with something specific, that is a signal the article is not ready to be written yet.
This is where most topical authority attempts break down. The gap between "drafted" and "approved" is where the useful content lives. Before publishing, each article should pass a basic quality check: does the first paragraph directly answer the question? Is there at least one specific, verifiable claim a generative model could not have made up? Does it link to related articles on the site? Has a human read it and confirmed it is actually useful, not just adequate?
That last step, human approval, is non-negotiable if you are using AI assistance in the drafting process. Not because AI content is inherently penalised (Google's position is that unhelpfulness is penalised, not the tool used to produce content), but because AI without oversight produces confident generalities, and confident generalities do not build topical authority. They fill space.
After publishing, watch how each article performs over 60 to 90 days. Which ones rank? Which attract clicks but not engagement? Which are cited in AI Overviews? The answers tell you what to do next. Articles that rank for unexpected queries reveal gaps you had not spotted. Articles that get clicks but bounce quickly need their opening rewritten. Articles that are cited in AI Overviews tell you what specificity and structure the model finds trustworthy, which is exactly what you should replicate in the next cycle.
Feed those findings back into step one and repeat. Over six to twelve months, a site running this loop will have built a library of interlinked, specific, regularly updated content that Google can consistently trust on its subject. That is topical authority in practice.
This approach is slower than a content blast and more demanding than outsourcing to a writing farm. The payoff is that it is also durable. A site with genuine topical authority survives core algorithm updates, because it has been doing the thing the updates are designed to reward. A site built on volume and shortcuts does not.
