Text SEO metrics: what to measure

Text metrics

The tool counts text volume, the frequency of words and phrases, keyword nausea and water content — the classic metrics of Russian SEO used to write briefs for copywriters.

These indicators help you spot over-optimization before publishing: keyword stuffing is still one of the main causes of Yandex penalties (the “Baden-Baden” filter).

How to write text that ranks

Start from the query intent: the text should answer the user’s question faster and more fully than competitors. Structure the content with headings, lists and tables — readers and search engines’ generative answers both value it.

Use the metrics as a constraint, not a goal: once nausea and water content are within norm, keep improving the substance, examples and expertise.

Frequently asked questions

What is keyword nausea?+

A metric of word-repetition frequency. Academic nausea is the ratio of repetitions to text volume; classic nausea is the square root of the most frequent word’s count. High nausea is a sign of stuffing, for which Yandex can lower a page.

What is water content?+

The share of stop-words and words without meaning (prepositions, filler phrases, clichés). The norm is up to 40–60%. Text that is too “watery” answers the user’s query poorly.

What is the optimal keyword density?+

There is no universal figure; a guideline is up to 2–3% per word. Naturalness matters more: modern algorithms (Yandex and Google neural networks) evaluate the meaning of the text, not the count of occurrences.

Will the analysis help against the “Baden-Baden” filter?+

Partly: the tool detects stuffing and unnatural frequency — the main triggers of the filter. But text quality is ultimately determined by usefulness to the reader, not just metrics.
