I run https://www.checkbot.io/ https://www.checkbot.io/ myself while doing consulting. It's a Chrome extension that checks multiple pages at a time for common SEO, speed and security issues. I started working on it initially to automate checks I was often doing manually while developing websites for others. Developers I worked with found it useful so I spun it out into its own product. I wrote the online guide on the website too that explains all the web best practices Checkbot tests which I'm trying to turn into an ebook as well.
