Checkbot will ask for the "Read and change all your data..." permission for the sole purpose of crawling and testing the websites you ask Checkbot to check. This is currently the most restrictive permission we can ask for that allows this and Google has also reviewed this extension to check it follows best practices on requesting permissions. Your regular browsing will be unaffected: Checkbot does not observe or modify anything outside of the Checkbot tab.

Redirect Path

The HTTP Header & Redirect Checker for SEO Redirect Path flags up 301, 302, 404 and 500 HTTP Status Codes as well as client side redirects like Meta and Javascript redirects, bringing potential issues that may not otherwise be seen to your attention immediately. As well as flagging up redirects and errors, the plugin also displays other HTTP Headers (such as server types and caching headers) and the server IP Address at the click of a button. All the magic happens on your computer, so it doesn’t “phone home” to anyone (except when auto-updating itself) and is instantaneous.
