What is an ideal keyword density for SEO in 2026?

An ideal keyword density is typically between 1.0% and 2.0%. Anything above 2.5% risks triggering Google's algorithmic keyword stuffing and over-optimization filters.

What is an n-gram in content analysis?

An n-gram is a contiguous sequence of 'n' items from a text. A 1-gram is a single word ('processor'), a 2-gram is a bigram ('cpu cooler'), and a 3-gram is a trigram ('pc power supply'). Analyzing n-grams reveals key topical phrases.

What does lexical diversity mean in content writing?

Lexical diversity measures the ratio of unique words to total words (Type-Token Ratio). High lexical diversity indicates rich, nuanced writing, which correlates strongly with high-quality helpful content.

Should I include my focus keyword in every heading?

No. Stuffing target keywords into every H2 and H3 heading appears artificial. Use natural semantic variations and synonyms that address specific searcher sub-questions.

Is this analyzer safe for confidential drafts?

Yes! All text analysis runs 100% locally in your web browser using JavaScript. No draft text is uploaded, transmitted, or logged.

Modern graphics cards have sudden transient power spikes, which means your PC power supply needs high wattage headroom. When building a gaming PC, always buy a Tier A rated power supply with ATX 3.1 certification.
