• Majestic. This is my link analysis tool of choice. I’ve used Majestic for years now, and you just can’t beat it when it comes to the accuracy of its stats. Don’t just take my word for it, though: here is a case study that Matthew Woodward wrote a little while back that reviews a number of link analysis tools.
• Ahrefs. Similar to Majestic, Ahrefs is a fantastic tool for link analysis, especially when it comes to finding fresh links. As far as I’m concerned, no link analysis tool identifies new links more quickly than Ahrefs.
• Open Site Explorer. Here’s the last of the big three link analysis tools. Open Site Explorer (a Moz product) definitely has a much smaller index than Majestic and Ahrefs; however, its UI is definitely the easiest to work with, and it’s great for link prospecting work.
• SEMrush. This tool is second to none for discovering the organic positions of a site that you don’t have analytics access for. It’s also a powerful keyword research tool. SEMrush is one of the tools I use most on a daily basis, especially when it comes to competitive research.
• Searchmetrics. Seriously powerful and packed full of amazing data, the Searchmetrics SEO suite enables you to track, manage and measure your entire SEO campaign (enterprise level).
• BuzzSumo. One of my favourite tools out there at the moment, I just can’t stop raving about BuzzSumo! In a nutshell, with BuzzSumo, you can filter through content relevant to your niche and sort it by the number of social shares across each social network. Similarly, you can compare different domains against each other to see which site is producing the most popular content.
• NerdyData. This one is a source code search engine (great for data analysis to go into your content). Using NerdyData, you can go through and look for specific code that appears within a website. For example, if you wanted to see all of the websites that have Facebook ad tracking code within them or that use a specific WordPress plugin, then this is the tool for you.
• URL Profiler. Much like BuzzSumo, I seem to be mentioning URL Profiler more and more of late. (I put together a full review of the software which you can check out here.) In short, URL Profiler enables you to extract big data from web pages in bulk so that you can perform content audits, link analysis and much more. This is so powerful as an analysis tool.
• Screaming Frog SEO Spider. Screaming Frog is powerful desktop-based website analysis tool. I use this tool as part of any SEO audit that I carry out, and it is also key in my broken link building strategies. (I recorded a full tutorial on using the tool here.)
• Long Tail Pro. This keyword research tool can be used to gather huge numbers of keywords for use within large campaigns. You can also pull in data from Moz surrounding keyword competition, as well.
• Quantcast. Get stats on website traffic to any website online without access to their analytics.
• Similar Web. This tool is similar to Quantcast, but it offers much deeper insights around traffic sources. Great for benchmarking your campaigns (I use Similar Web in tandem with SEMrush). It can also analyse mobile app traffic.
• Consumer Barometer. A project created by Google, the Consumer Barometer gives free consumer insights across a whole range of sectors. This is good for gathering stats to go into your content or to plug directly into your keyword research.
• Social Crawlytics. Gather social stats across any URL online, as well as further information around influential authors. You can even schedule reports to go out surrounding the activity of a specific domain, including new content, authors and social stats.
• Followerwonk. An advanced Twitter analytics platform owned by Moz, Followerwonk lets you analyze the followers of your competitors, search for influencers and track the success of your Twitter campaigns.
• Keyword Eye. This entry level keyword research tool is awesome for individuals, bloggers and businesses. It’s low cost and very visual, making it perfect for beginners and advanced users alike.
• Keyword Snatcher. Here is another one of my favourite keyword research tools. It pulls back huge quantities of results, using YouTube, Amazon, eBay, Google, Yahoo and Bing as data sources. It’s a one-time payment tool, as well, which is ideal for those that are budget conscious.
• Keyword Tool. This newcomer has been creating quite a stir within the SEO community. It looks like a really powerful keyword research tool, and I’m excited to see how it develops.
• Search Man. If you’re interested in app store optimization, this is a great keyword research suite for mobile apps. Essentially, you can use this like you would any other keyword research tool, but it gives you app-specific information.
