Copywritely is SEO content analysis aimed at pages you have already published rather than at generating new ones. It identifies what is stopping a page ranking and gives interactive tips for fixing it in the editor.
The checks are specific rather than a single score: plagiarism, keyword density and relevance, keyword suggestions, grammar, hard-to-read sentences, difficult words, rewriting autodetection and URL analysis. Rewriting autodetection is the notable one – it flags text that reads as spun or machine-rewritten, which is exactly what search engines have got better at penalising. A Chrome extension, document history, document sharing and an API sit around the core tool, and the interface is available in a dozen languages.
Pricing is public and volume-based on documents per month: Basic at $29/mo, Beginner at $69/mo (or $55/mo billed yearly) with 25 documents a month and 8 supported languages, with 30% off annual billing and a free trial to start. A set of free tools – duplicate content checker, readability checker, word counter – sits outside the paywall.
