In brief: Topical authority is an informal term for the extent to which a website or author covers a particular area consistently, in depth, and with credible connections between content, experience and sources.
How I use Topical authority in practice
In practice, I do not use the term Topical authority as just another number for a presentation. First, I determine which decision it should make more precise, which data or observations it is based on, and who will change something as a result. I map real customer questions, gaps in content, internal links and the pages that should bring the topic to a decision-making conclusion. I also record the baseline, measurement date and limits of interpretation. This makes it possible later to distinguish a real shift from a change in the tool, sample or query wording.
What to watch out for
The greatest risk is precision that only looks real. Producing hundreds of superficial articles around a keyword does not create authority, and Google provides no public topical authority score. I therefore compare the result over time, on a stable sample and together with business context. If the term does not lead to a specific next step, the result is not analysis but merely a new label.
Questions for decision-making
- Which parts of the topic are genuinely relevant to the offer?
- Where do we have our own experience or data?
- Do the related pages lead to the main decision?
- What would be better to combine or remove?
