GUIDE

How to use Entity Coverage

Start with the exact page you want to improve and paste competitor URLs that already satisfy the search intent. The tool extracts recurring topic entities from titles, headings, schema, and body copy, then compares them with your page.

Use the result as a rewrite brief, not a stuffing checklist. Missing entities should become useful definitions, examples, comparisons, FAQ answers, tables, internal anchors, or section headings.

The best workflow is simple: fix missing high-consensus entities first, strengthen weak ones second, and ignore anything that does not help the reader complete the search task.

FAQ
Is this the same as keyword density?
No. Keyword density counts repeated words. Entity coverage checks whether a page includes the concepts and named things competitors use to explain the topic.
Does it need paid APIs?
No. The MVP uses the public HTML of your page and manually supplied competitor URLs. A paid SERP API could later auto-fill competitors.
How many competitors should I add?
One works, but three to five direct ranking pages give a more stable model and reduce noise from a single competitor.

How to check semantic coverage of a page

  1. Enter your page and the query it is meant to rank for.
  2. The tool extracts entities from your copy and from the competitor pages ranking in the top.
  3. Review the gap list: topics and concepts competitors cover and you do not.
  4. Use the result as a content brief: add the missing sections rather than isolated keywords.

What entity SEO and semantic coverage mean

Search engines stopped working with strings long ago and now work with entities: people, companies, products, places and concepts, plus the relations between them. A page ranks for topical completeness, not keyword density.

Semantic coverage shows how completely your material addresses the topic compared with the pages already ranking. A coverage gap is the most common reason a technically clean page stalls outside the top ten.

Entities must be added meaningfully, not as a list. A mention with no explanation improves understanding neither for the reader nor for the algorithm.

Frequently Asked Questions

What is an entity in SEO?
An entity is a specific thing a search engine recognises and understands: a brand, person, product, city, technology or concept. Unlike a keyword, an entity does not depend on wording or language.
How is this different from keyword density?
Density counts repetitions of one phrase; entity coverage measures topical completeness. You can hit perfect density and still miss half the subtopics competitors cover.
How many competitors should I compare?
A handful of top-ranking pages for your target query is enough. If an entity appears in nearly all of them, it is a required part of the topic rather than a random term.
Does this help with AI answers?
Complete, well-structured topical coverage raises the chance a page gets cited in an AI answer, because the model looks for a source that answers the question fully rather than partly.
