Entity & Phrase Extraction
Identify capitalized named entities, technical acronyms, and multi-word domain phrases across up to 3 competitors.
Missing Subtopic Discovery

Questions and answers
Semantic entity & competitor gap questions
What does the Semantic Entity & Competitor Content Gap Analyzer do?
It compares your page or draft against 1 to 3 ranking competitor pages to identify named entities, technical phrases, and H2/H3 subheadings that competitors cover but your content misses.
How is semantic entity coverage different from old-school keyword density?
Keyword density measures how often a single target keyword repeats, whereas semantic entity analysis checks whether your article covers the related tools, standards, metrics, and subtopics that search engines expect in an authoritative piece on that topic.
What are the 4 entity buckets in the report?
Terms are grouped into: (1) Missing Critical Gaps (used by competitors, 0 mentions on your page), (2) Under-Used Terms (present on your page at less than 45% of competitor frequency), (3) Well-Covered Core Entities, and (4) Unique to You (terms that give your article original Information Gain).
Can I compare unpublished drafts without live URLs?
Yes. Use the 'Compare Pasted Drafts / HTML' tab to paste your draft alongside competitor text and run the comparison offline.
Should I stuff every missing entity into my article?
No. Only add entities and subtopics that genuinely help answer the reader's intent. Adding a short, accurate section or table is always better than forcing isolated words into existing sentences.
