Topic completeness

Find out if your page explains its topic well enough to be used

Content Coverage reads a page, works out the one topic it is explaining, then checks it against what a complete page on that topic would cover. You get what is answered, what is partial, what is missing, and what to fix first. It is the analysis behind your Answer Readiness score.

Topic this page explains

How active noise cancelling works

One clear anchor topic. The page explains the mechanism well and stops short of what a reader does with it.

The idea

Thorough is not the same as long.

A 3,000-word guide can miss the four things a reader actually needed, while a short page covers its topic completely. Length is not the measure; whether the topic is closed out is.

Covered a lot of ground

History, background, three analogies and a conclusion. Reads like an authority. Never says which situations it does not work in, so an assistant summarising it cannot warn anyone — and quietly prefers a page that does.

Closed out the topic

Explains the mechanism, names the trade-offs, states the limits, and says who it is not for. Shorter, and now it is the page worth citing because nothing important is left dangling.

A real result

What is missing, ranked by what it costs you

Gaps come back ordered rather than as a flat list, because the point is knowing which one to write first.

Critical The page never says when noise cancelling does not help It explains the mechanism thoroughly, then stops. Readers arrive wanting to know whether it will work for them — on a plane, in an open-plane office, against speech — and the page does not say. This is the single most-asked follow-up on the topic.
Critical No mention of the trade-off with sound quality A concept a complete treatment of this topic always covers. Its absence is why the page reads as promotional rather than explanatory.
Important Passive isolation is referenced but never distinguished from active The two terms are used interchangeably in one paragraph. A reader — or a model — cannot tell which one the page means.
Important No guidance on what to look for when choosing The topic is explained but not made actionable, so the page loses the reader at the point they were ready to decide.
Minor Battery impact is mentioned once, in passing Worth a sentence rather than a rewrite.
What this is not It is not a word count, a keyword check, or a readability score. Two of these gaps are single paragraphs — the page does not need to be longer, it needs to stop leaving the topic open.
Across page types

“Complete” means something different on every kind of page.

The topic is detected from the content, not the URL, and what counts as covering it changes with the kind of page you wrote.

Long-form guides and articles

The type with the most room to leave a topic open.

  • the mechanism
  • trade-offs
  • when it does not apply
  • how to choose
  • common mistakes
  • what to do next

Product pages

Usually strong on features, thin on fit.

  • what it does
  • who it is for
  • who it is not for
  • specifications
  • compatibility
  • what is included

Comparison pages

Frequently argue one side and call it a comparison.

  • both options fairly
  • the criteria
  • when each one wins
  • what they share

Pricing pages

Often complete on plans and silent on the edges.

  • what it costs
  • what is included
  • billing terms
  • what happens at the limits

Category and collection pages

Frequently a grid with no explanation attached.

  • what belongs here
  • how the options differ
  • how to narrow it down

Homepages and landing pages

The hardest type to close out, because the topic is the company.

  • what you do
  • for whom
  • what makes it different
  • proof
  • the next step

FAQ

Coverage, answered

Is this telling me to write longer pages?

No. Length is not the measure and padding makes results worse, not better — a page that spreads thin reads as being about nothing in particular. The measure is how many of the questions a reader has on this topic the page actually resolves.

Which pages does this work on?

Anything with substance to read. Long-form articles and guides, product and pricing pages, comparison pages, category and resource hubs, homepages, documentation. It is weak on thin pages, login flows and pages that are mostly navigation, because there is not enough there to evaluate — and that is a finding in itself.

How do you know what a complete page on my topic looks like?

It works out the one topic the page is explaining, then builds the set of questions a page on that topic should answer and the concepts it should cover. Every question comes back answered, partial or missing. The expectations come from the topic, not from a template — complete means something different on a pricing page and on a guide.

How is this different from a readability or content score?

Those grade the writing — tone, sentence length, keyword density. Useful for people, close to irrelevant here. A perfectly readable page that never answers the obvious question is a bad source. Completeness first, quality second.

What is the fastest thing to fix?

The partial answers. The page already touches those questions, so the material exists — it is implied, split across sections, or half-stated. Consolidating one into a direct statement is usually a paragraph of work and moves the count.

What if the page covers more than one topic?

You will see it as a low confidence score on the detected topic, and that is the finding. Before chasing individual gaps, decide what the page is for — a page that reads as being about three things is hard for anything to classify, and every signal downstream stays weak until it is one thing.

What is “concepts integrated”?

The ideas a reader needs the page to explain, not just mention. Naming a concept in passing and explaining it are different things, and the difference is what a system weighing your page as a source notices.

Can it write the missing sections?

Yes. Optimizations drafts the missing answer or section for each gap, built from content already on the page, with anything the page never stated flagged for you to confirm.

How does this relate to Answer Readiness?

Answer Readiness is this analysis, expressed as a score. Content Coverage is the detail behind it — the topic, the questions, the concepts and the ranked improvements.

How is this different from Prompt Fit?

Coverage judges the page against its whole topic — everything a complete page should cover. Fit judges it against one specific question. Close the broad gaps first, then test the individual prompts you want to win.
