Checkbot finds SEO, speed & security problems before your website visitors do·checkbot.io

Checkbot is a Chrome browser extension that audits websites for SEO, speed, and security problems. It crawls hundreds of pages at once to detect issues such as broken links, duplicate content, invalid HTML/CSS/JavaScript, insecure pages, and redirect chains against more than 50 best-practice checks. It can crawl local development and staging sites, password-protected pages, and private-network sites, and export findings to PDF and CSV. In-app help explains what each issue means and how to fix it.
