WebFX Readability Test Tool

What WebFX Readability Test Tool is
WebFX Readability Test Tool analyzes webpage text and reports six readability scores, including Flesch Kincaid Reading Ease, Flesch Kincaid Grade Level, Gunning Fog, Coleman Liau, Automated Readability Index, and SMOG. You can submit a URL, type or paste text, upload a TXT, DOC, or DOCX file, or refer the tool from a website. Results include word and sentence counts, complex-word count and percentage, average words per sentence, and average syllables per word. Highlights identify hard and very hard sentences, passive voice, and adverbs. For webpage tests, you can analyze the whole page or target a specific area using a page element. HTML in text input is accepted and removed before analysis. The tool is free on the web, with a listed plan price of $0 and no free trial. WebFX was founded in 1995 and is headquartered in Harrisburg, Pennsylvania. Pages using React, Vue, or JavaScript may show a word count of zero; URL analysis also cannot reach gated content. WebFX suggests pasting the text in those cases.
