So what the f*** are these websites and why would you want a link from them? And when it really drills down to it; are the links valuable?
In SEO we can these websites aggregators. These sites generally scrape and aggregate publicly available data about domains and websites to provide insights, analytics, and various tools for webmasters, marketers, and users interested in website performance, security, and value. They have mostly been around for years, and since the data is relevant and useful for some other tools on the internet, they attract a ton of backlinks themselves, increasing their DR.
