This massive site exporter/backlink checker has become the go-to tool for many SEOs. Just drop a competitor’s URL and get the freshest backlink index available that includes a nice intuitive graph along with intuitive metrics (URL rank, Ahrefs Domain Rank, Backlinks, etc). There are several ways to use this tool to spy on your competitors. For example, you’ll also get breakdowns that will parse out .gov and .edu links, new links, broken links, etc.
Other useful metrics include domain comparison (perfect for checking your backlink profile against those of competitors), and a whole new “content” section which shows which of your pages are attracting most of the links.
ahrefs
Ahrefs.com has a lot of overlap with Moz’s Open Site Explorer and Majestic, but I prefer this, as I find it has the freshest index, which helps me stay current. All three tools are worth their weight, however (OSE comes packaged as part of Moz Analytics so it may be the best bang for your buck, whereas Majestic’s “old/outdated” index (Majestic has the “largest” index, but it includes old links that no longer exist) can be helpful for historic purposes.
Plans range from $79/month to $1,299/month. That said you can get some limited usage for free. If you’re looking to stick to a free tool, there are several options out there. Like ahrefs, OSE, and Majetic all allow for some free limited usage. That said, one of the best free online backlink checker tools I’ve come across is Open Link Profiler. The amount of data and detail they’ll show for a backlink profile (for free) is pretty impressive.

A1 Website Analyzer
This tool is a beast. While it’s largely helpful in analyzing your own websites and finding errors and areas for improvement, it’s also helpful in analyzing competitor websites. The URL “importance” score can tell you which of your competitor’s pages are most important (in terms of internal link building, placement, etc.) and you can also look for specific content on their website (using the same function used for auditing GA tracking or other scripts).
You can play with the data within the tool or export into Excel and play with it there. It might seem overwhelming at first because of the sheer amount of data that it passes (it’s more than “traditional SEO” data), but you can filter out what you don’t want/need, and it becomes intuitive with little use anyhow. This tool is very similar to Screaming Frog SEO Spider. To date, I still prefer A1 WSA. It’s less intuitive but the flexibility (once you’ve learned how to work the tool) really allows you to filter exports and removes the need for subsequent work in Excel.

Your Brain
Tools that automate what once required painstaking manual work are great. They allow us to batch process much of the collection and filtering and free us up to work on more projects. That said, we must be careful not to become so dependent on tools that we become accustomed to outsourcing our critical thinking and just end up doing little more than analyzing columns in spreadsheets.
Spend some time on your main competitor’s websites. What makes them your main competitor? Why do they deserve the (natural) links that they have? What’s their unique selling perspective? What does their site’s design convey? Be as objective as you can. How would a first-time user feel landing on their website compared to yours? Again, the tools mentioned above are great but don’t skip out on doing your own analysis. So, put that prefrontal cortex to use!
Go forth and research!
These are by no means the only Web or SEO spy tools out there. However, they are the tools I have found most valuable. Feel free to give your 2 cents on these tools and/or share other SEO spy tools that have worked for you.
