Why Readability is a Core SEO Metric
The single most underrated SEO metric is Dwell Time (how long a user stays on your page before clicking the 'Back' button). If your readability is poor, users bounce. When users bounce, Google demotes your rankings.
The Flesch-Kincaid Readability Formula
Our tool uses the standard Flesch-Kincaid mathematical formula, which evaluates:
- Total Words / Total Sentences: Long, run-on sentences lower your score.
- Total Syllables / Total Words: Complex collegiate vocabulary lowers your score.
The Golden Rules of Web Writing
Never try to sound "smart" by using complex words when simple ones will do. Use "use" instead of "utilize". Use "help" instead of "facilitate". Keep paragraphs to a maximum of 3 sentences.
