Write SEO-optimized articles with realtime scoring — like Yoast, but free and in your browser.
SEO Content Editor is a free online tool for writing SEO-optimized articles with realtime scoring and actionable suggestions. Enter your target keyword and start writing — the editor analyzes keyword density, readability, heading structure, content length, and more as you type. Search engine optimization starts with content. Well-structured, keyword-optimized content ranks higher in Google search results and drives more organic traffic. This editor helps you follow SEO best practices without being an SEO expert by providing instant feedback on every aspect of your content. The analyzer checks keyword density and placement (title, headings, first paragraph, meta description), content length and readability, heading hierarchy (H1-H6 structure), paragraph length and sentence complexity, and internal/external link suggestions. Each factor is scored individually and combined into an overall SEO score. Everything runs entirely in your browser. Your content is never sent to any server, making it safe for drafting confidential articles, client content, and unpublished blog posts. There are no usage limits and no account required. Common use cases include writing blog posts optimized for specific keywords, auditing existing content for SEO improvements, training content writers on SEO best practices, preparing product descriptions for e-commerce, and optimizing landing page copy for search visibility.
