Pros: I manage multiple client accounts and Ahrefs is one of the tools that I rely on for basic site metrics every day. There are certain things it does very well. The first is KW research. It gives you everything you need to craft content that will rank. I also like the information it provides about broken links - it's precise and points out what you need to fix immediately. I also frequently put it to use when I'm looking into new domains. It's easy to use and has a friendly user interface. The support team isn't too bad - they don't take too long to respond to queries.
