Keyword Research & Content Analysis Guide

On-page keyword research helps you understand what topics and phrases your content actually covers. By analyzing word frequency, you can identify overused terms, spot missing keywords, and align your writing with target search queries.

Keyword Density (%) = (Keyword Count / Total Word Count) × 100

Multi-word phrase extraction (bigrams and trigrams) reveals the natural language patterns in your text, helping you optimize for semantic search and voice queries. A healthy keyword density typically ranges from 1–3% per target term.

Frequently Asked Questions (FAQ)

Q: What is keyword density and why does it matter?

A: Keyword density measures how often a word appears relative to total word count. It helps prevent keyword stuffing and ensures balanced content. Most SEO guidelines recommend 1–3% density for primary keywords.

Q: How are bigrams and trigrams useful for SEO?

A: Bigrams (two-word phrases) and trigrams (three-word phrases) help identify natural language patterns and long-tail keyword opportunities. Search engines use n-gram analysis to understand content context and relevance.

Q: Does this tool connect to Google or any API?

A: No. All analysis runs locally in your browser. No text is sent to any server, making it safe for confidential or draft content. The search volume indicator is a heuristic based on word count and density — not real API data.

Q: What is the minimum text length required for accurate analysis?

A: For statistically meaningful results, we recommend at least 150–200 words. Shorter texts will still work but keyword density percentages may appear exaggerated.
