About Sentence Counter
Sentence length is a key factor in content readability and SEO performance. Google favours content that is easy to read — and short, varied sentences are a core part of that. Our free sentence counter analyses your text and shows total sentence count, average words per sentence, the longest sentence, the shortest sentence, and a readability indicator. Ideal sentence length for SEO content is 15–20 words on average. Use this tool to identify overly long sentences before publishing. No signup required.
