Topical Authority Calculator

Score topical authority across coverage, depth, links and engagement.

About Topical Authority Calculator

Each dimension is scored out of 100 and combined using its normalised weight, so the result stays on a 0-100 scale. The weakest dimension is surfaced separately because a good average routinely hides one failing area. A single topical authority number is what gets reported upward, but the weakest-dimension line is what tells you where the next hour of work should go.

Formula

Topical Authority

Score = Σ (dimension × weight), weights normalised to 1

dimension: Each contributing measure, scored 0-100
weight: Relative importance of that dimension

Worked example

Assumptions and limits

The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Topical Authority calculated?

Score = Σ (dimension × weight), weights normalised to 1 Each dimension is scored out of 100 and combined using its normalised weight, so the result stays on a 0-100 scale. The weakest dimension is surfaced separately because a good average routinely hides one failing area.

Why does Topical Authority matter?

A single topical authority number is what gets reported upward, but the weakest-dimension line is what tells you where the next hour of work should go.

What values do I need to enter?

This calculator takes 5 inputs: Share of the topic cluster covered, Average content depth, Internal linking within the cluster, External links to cluster pages, Engagement on cluster pages. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
