Keyword stuffing: what it is and how to fix it

Keyword stuffing is when target phrases and same-root repeats pile up until the page reads like it was written for a bot. Search engines dislike it. Readers bounce even faster.

Below: how stuffing shows up, why teams still use Advego and text.ru, and how to lower density without turning the article into empty filler. Tool scores are a brief guideline — not a ranking law.

What counts as stuffing

It’s how often keywords (and close forms) show up relative to the length of the text. Keywords belong in the topic — racing to plant the query in every sentence breaks the language.

A classic anti-example: a product blurb where one commercial phrase repeats dozens of times with tiny swaps. Formally “optimized.” In practice — spam.

Stuffing usually looks like:

  • the same words in every paragraph
  • unnatural query chains
  • keyboard-layout tricks and typos “for uniqueness”
  • copy a human can’t finish reading

How it connects to rankings

Relevance matters, but search also judges usefulness, uniqueness, and on-page behavior. Stuffing erodes trust and UX — bounce goes up.

Ranking uses many signals. A third-party “nausea %” is not plugged into the algorithm. Treat the tool as an editor’s helper. Cleaner copy is part of prep; ranking gains for a competitive set are still planned over months (often 2–6), not the day you lower a density score.

Tools that check density

text.ru reports stuffing, uniqueness, and often spelling issues. Advego reports classic and academic “nausea” — two different density formulas.

Istio, PR-CY, and desktop analyzers are alternatives. Numbers won’t match one-to-one across tools, so name the instrument and threshold in the brief.

A practical brief approach:

  • name the tool and the threshold
  • require human readability
  • don’t chase a “magic” percent at the cost of meaning
  • recheck the final text after edits

How to reduce stuffing

Cut spare keyword repeats, swap some for synonyms and pronouns, and rebuild awkward sentences. Passages you can’t save — delete.

Working order:

  • find the top frequent words in the report
  • keep the keyword where it still carries meaning
  • smooth with natural speech, not fluff
  • don’t spawn same-root forms in every paragraph
  • read aloud and send for a final proofread

FAQ

What stuffing percentage counts as “normal”?

On text.ru the usual advice is “don’t go to extremes”; briefs often ask for a moderate zone (roughly up to ~45–50% on their scale). Always match the specific tool — the scales don’t line up.

Does a high Advego “nausea” score mean a search ban?

No direct formula. High classic or academic nausea just flags lots of repeats. Engines weigh meaning, behavior, and overall page quality — not one third-party percentage.

Should I pad the text with fluff to drop the score?

No. Use synonyms, pronouns, rephrasing, and cut spare keywords. Fluff damages the copy in a different way.

Are keywords in the title tag spam?

One natural main idea is fine. A comma chain like “buy cheap wholesale city urgent” is already stuffing.

What else should I check with?

Advego, text.ru, Istio, and similar tools — plus common sense: read it aloud. If you stumble, edit.
