SEO text analysis is an essential step in content preparation before publishing. Search engines evaluate text quality based on numerous parameters, and over-optimization (as well as under-optimization) can negatively affect rankings.
Classic Nausea
Classic nausea is the square root of the frequency of the most commonly used word in the text. If a word appears 25 times, the classic nausea = √25 = 5. The recommended value is no more than 7. High classic nausea indicates excessive use of a single word.
Academic Nausea
Academic nausea is the ratio of the sum of all repeated word frequencies to the total word count, expressed as a percentage. It shows the overall "spamminess" of the text. The norm is 7–9%. Below 7% — the text may be under-optimized. Above 9% — there is a risk of keyword stuffing.
Water Content
Water content is the proportion of stop words (function words, filler phrases, and words that carry no semantic weight) relative to the total word count. Stop words include: prepositions, conjunctions, particles, and introductory phrases. The recommended value is no more than 60%. High water content indicates vague, non-specific text.
