What WebFX Readability Test Tool is
WebFX Readability Test Tool analyzes webpage text and reports six readability scores: Flesch Kincaid Reading Ease, Flesch Kincaid Grade Level, Gunning Fog, Coleman Liau, Automated Readability Index, and SMOG. It also reports 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. You can provide text through a webpage URL, by typing or pasting it, or by uploading a TXT, DOC, or DOCX file. For webpages, the tool can analyze the whole page or a specific area identified with a page element. HTML in text input is accepted and stripped. The tool is free to use on the web. WebFX says URL analysis may return a zero word count for pages using React, Vue, or JavaScript, and it cannot score gated content; it suggests pasting the page text in those cases. The tool is presented by WebFX, whose headquarters are in Harrisburg, Pennsylvania.
