Entity SEO Analyzer
Paste a page's HTML or text and get a heuristic read on its entity consistency, heading structure, and semantic flow. Everything runs in your browser: nothing you paste is uploaded, stored, or sent anywhere.
What it is
A free, experimental, rule-based analyzer that runs entirely in your browser. It reads one page at a time and scores structural signals used in entity-based SEO: where your primary entity appears, how your headings are organized, and how declarative your sentences are.
What it does
Checks your title, H1, meta description, and H2s for entity consistency. Estimates semantic-triple flow (subject-predicate sentence patterns, passive voice, hedging). Detects JSON-LD schema types, repeated phrases, capitalized entities, and internal linking. Then gives you a prioritized fix list.
What it isn't
Not an NLP model, not Google, and not a rank tracker. It cannot measure rankings, crawlability, backlinks, or search volume, and its entity and triple detection are pattern-based approximations that can be wrong. Treat results as editorial prompts, not verdicts.
Best results: open your page, View Source, copy everything, paste here. Plain text works too (with fewer checks).
Runs locally in your browser. Nothing is uploaded or stored.
Entity consistency
Detected primary entity: (auto-detected, override above if wrong)
Page basics
Semantic flow
How extractable and declarative the writing is. A semantic triple is a subject-predicate-object claim ("Topic clusters build authority").
- Triple-style sentences
- Passive voice
- Avg words / sentence
- Hedge words
- H2s answered directly
Repeated phrases & named entities
What the page appears to be "about" from raw repetition.
Not enough repeated phrases detected. That usually means thin content or highly varied vocabulary.
Structured data & links
None detected.

Prioritized suggestions
Nothing critical flagged. The signals this tool can see look consistent.
Disclaimer
This is an experimental, educational tool provided as-is, with no warranty. It uses transparent, rule-based heuristics, not machine learning, not Google's systems, and not any third-party API. "Entity", "semantic triple", and "consistency" scores are approximations of writing patterns, and they can misread your content, especially non-English text, heavy templating, or unconventional markup. It does not crawl your site, measure rankings, evaluate backlinks, or predict traffic, and a high score here is not a promise of search performance. All analysis happens locally in your browser; the content you paste is never transmitted to, or stored on, this server. For a human read on your actual rankings, request a free audit.
