3. Internet Archive (Wayback Machine) Differences – Compares the the current version of a page to a snapshot in the Internet Archive Wayback Machine. This is fantastic way to analyze changes to a website and research site issues if you are not currently using SEORadar to archive your pages. (Caveat: if you choose the home page of a very popular site, there will be a delay because there are so many snapshots).
4. Internet Archive URL Tester – This test does an HTTP status check on URLs in the Internet Archive. You provide a domain and a date range, and SEORadar will ping up to 1000 URLs and produce a spreadsheet with the results. This is a great way to diagnose historic issues with content disappearing and URLs not getting properly redirected.

However, for a noindex tag, you might want an email and a text message. Configure the system to meet your own priorities. You can even supresss specific alerts on particurlar URLs.
