SEO Tools
Analyze any public webpage for word count, characters, reading time, keyword density, headings, metadata, and SEO content breakdown.
Enter a public URL, paste text, upload a document (PDF, Word, PowerPoint, OpenDocument, RTF, HTML, Markdown, code, CSV/JSON, and more), or run a small bulk URL check to count words, characters, sentences, paragraphs, unique words, reading time, speaking time, keyword density, heading structure, title/meta lengths, boilerplate ratio, anchor text words, and main-content word count. The tool uses your own free Next.js API route and does not require a paid third-party API.
