How It Works

Understanding the logic and mathematics behind the precision.

Core Algorithm

Readability = 206.835 - 1.015(Words / Sentences) - 84.6(Syllables / Words)

Calculates the standard Flesch Reading Ease score to optimize content readability.

Keep keyword density below 3% to avoid Google spam classification. Natural language flow always wins.

Aim for a score above 60 to ensure content is accessible to general audiences, reducing high bounce rates.

Ensure target terms are matched in headers and naturally distributed across the body paragraph zones.

A score between 60 and 70 is standard conversational English (easily understood by 8th graders). Higher is easier; lower indicates complex prose.

Separate multiple keywords with commas in the target keyword input. The analyzer checks each phrase to ensure it meets ideal 1.5% densities.

No! Pro Pass users can scan articles of any length and compile as many optimization reports as needed.
