Frequently Asked Questions (10)

What is an optimal keyword density percentage for SEO?

A primary keyword density between 1.0% and 2.5% is generally considered natural and optimal. Densities exceeding 3.5% risk triggering search engine keyword stuffing filters.

What is the Flesch Reading Ease score and how is it graded?

The Flesch score measures text readability on a 0-100 scale. Scores from 60 to 70 represent plain, conversational English understood by 8th graders. Scores above 70 are easy to read, while scores below 50 reflect dense academic prose.

Does this analyzer automatically filter out common stop words?

Yes. Common stop words (such as "the", "is", "at", "which", "and") are filtered out so that only your genuine topical keywords and 2-to-3 word phrases are highlighted.

What are n-grams and why are multi-word phrases important for SEO?

N-grams are recurring combinations of 2 or 3 consecutive words. Multi-word phrases help you identify long-tail keyword targets and ensure natural semantic depth.

How does sentence length affect user engagement and dwell time?

Shorter sentences (averaging 14 to 18 words) improve scannability on mobile screens, reduce bounce rates, and keep readers engaged longer.

Can I analyze both live website URLs and pasted draft text?

Yes. You can paste raw draft copy directly or fetch content from any live URL to audit competitor articles and existing published blog posts.

How does reading ease correlate with Google search ranking?

Google prioritizes helpful content that satisfies searcher queries efficiently. Clear, easily digestible copy increases user engagement and reduces bounce rates.

What is the Flesch-Kincaid Grade Level metric?

It translates reading difficulty into United States school grade levels (e.g., Grade 8 corresponds to an approximate reading age of 13-14 years old).

How should I fix a keyword stuffing warning in my copy?

Replace excessive repetitions of the exact match keyword with natural synonyms, contextual variations, pronouns, or LSI (latent semantic indexing) phrases.

What is estimated reading time based upon?

Estimated reading time is calculated using an average adult silent reading speed of 200 to 225 words per minute.
