SEO Spyglass is a decent tool for learning more about your competitor's sites and backlinking efforts, and Rank Tracker is helpful to keep a daily historical record of how you rank on a list of keywords, so you can see if you are making any progress. Link Assistant is basically a tool to keep all of your backlinking efforts organized into one place, so you can see which ones you've completed, which are still active, and which ones you still need to reach out for. Website Auditor and Buzz Bundle I don't use, there are plenty of free online tools to audit your pages for on-page optimizations, and I don't advertise much on social media to bother with Buzz Bundle.
My big gripe with the program is that it's already expensive, but then on top of that, you need to pay for an additional subscription service from them to help bypass all the "Captchas" you will get hit with when trying to pull reports. It makes the program practically unusable at times. They should have included some option to simply input your own list of proxies or something like that.
Supposedly they have some new method of getting you referring search queries back in your Google Analytics reports (since Google now hides most of them) with like a 96% accuracy, or something like that - which, if it works, might also make the software worth purchasing.
