Why density is outdated
In the past, optimizers mechanically calculated keyword percentages and aimed for a 'golden mean'. Today, Google’s algorithms understand synonyms and context, and density is just one of many signals. Moreover, chasing a specific percentage often led to stuffing.
What replaced density
- TF‑IDF — evaluates word importance in a document relative to a collection of documents.
- LSI (Latent Semantic Indexing) and BERT — understanding meaning through context.
- Semantic coverage — how completely the topic is covered using related terms.
Connection to stuffing
Attempting to artificially raise density to 5–7% often leads to keyword stuffing. Instead, write naturally, satisfy intents, and use diverse topic‑related words.
Tools that show an 'ideal' density do not reflect modern SEO. Trust SERP analysis and common sense.
FAQ
Is there any safe density range?
No exact range exists. Avoid repeating the same word in neighboring sentences. If a keyword appears more than 2–3 times per 100 words, consider adding variety.
How can I check density without outdated tools?
Use spam checks (e.g., Textise or built‑in SEO extension analyzers), but don’t rely on 'ideal' numbers.
Does density affect Yandex rankings?
Yandex has also moved away from mechanical density. Algorithms like Baden‑Baden penalise stuffing, not low density.
