I like that Woorank has a powerful platform to analyze and optimize SEO for any site.. I also like how they offer a free site audit and a 14 day free trial period. I also like how they offer white label reports, which is great for agencies. I also like how you can get help from a certified expert.

Review: Capterra

Pros: The design is focused on what you need, and you don’t get lost in SEO or SEM jargon. You can do a Site Audit, which gives you actionable information (and if you’re a consultant, a huge benefit to give your clients). Keywords lists are delivered and organized in a way that again gives you actionable items, as is the PPC research. Content marketing is made simple,. with suggested ideas, questions, and all outlined in a way that you can feel smart taking these actions. Excellent support always, and the downloadable Excel spreadsheets help you share this info beyond SEMRush.

Cons: The con is a basic con with all SEO/SEM tools in the age of Google. PPC data is rarely accurate in terms of what companies are spending, not the fault of SEMRush as much as the sources are unreliable (yes Google, talking about you), which makes what used to be an accurate measure more of a guess. Still you will get an understanding, but the PPC end must be looked at more from Adwords than trusting this tool, or any tool.

Bottom Line is the go-to SEO tool for keyword research and investigation. While its narrow focus and lack of broader feature set preclude it from garnering an Editors’ Choice, KWfinder is an affordable, easy-to-use, and inherently valuable tool to have in your SEO arsenal.

Review: 3hundrd

SEO tools are common, from the best of the best (i.e expensive tools) such as Ahrefs and Moz to little know keyword tools such as Jaaxy (which is what I personally use for my keyword research).

Me being an SEO-er and search engines being my #1 source of traffic for my web properties, I am constantly “on the hunt” to find that next great tool that can show me data and numbers to continue improving my SEO efforts.

Today, I stumbled up SEOBility, a tool I have not heard of just yet (and probably you haven’t either) and I decided to try on their free 1-site trail and bring to you this SEOBility review which I think you’d find interesting if you are interested in checking your website’s SEO.

Review: TrustRadius

Great tool for tracking website rankings, SEO, and analytics. It provides a snapshot of important metrics, so you can quickly know where a site stands among the competition. I find the tool particularly helpful as a browser extension, which allows me to determine site influence immediately, without the need for any further investigation.

Pros and Cons

  • Website Ranking
  • SEO


  • More robust tracking of
  • backlinks
  • Likelihood to Recommend

Moz works great if you’re looking for an easy-to-use tool to track website performance and ranking. I would recommend it to businesses who rely upon search engine optimization, including keyword searching, and crawling.

If you’re a small business owner, you might find it more expansive than necessary. I wouldn’t recommend it if you’re a small shop looking for a few basics.
