What is content analysis for SEO
Content quality is one of the key ranking factors. Search engines can detect thin content, keyword stuffing and intent mismatch. Our tools help you align text with Google's requirements.
The Text Analyzer shows the frequency of each word with Russian morphology support: "buy", "bought", "purchase" all map to the same lemma. This gives you a true picture of keyword usage rather than scattered word forms.
TF-IDF analysis lets you compare your text against the top-ranking pages and find topics that competitors cover but you don't. This is the most precise way to improve page relevance.
Frequently Asked Questions
What is water content in text?
Water content is the share of words that carry no semantic value: pronouns, prepositions, conjunctions, filler phrases. Normal is below 40%. High water content reduces information density.
What is TF-IDF?
TF-IDF (Term Frequency — Inverse Document Frequency) measures how important a word is to a specific document relative to a corpus. Search engines use it to assess page relevance.
Do you support languages other than Russian?
Yes. The Text Analyzer supports Russian (pymorphy3), Ukrainian (pymorphy3 uk) and English (Snowball stemmer).
How do I reduce water content?
Replace filler phrases with specific facts, remove filler words ("is", "provides", "performs"), and use active voice instead of passive.
