If you don't know the first thing about keyword research, learn about it, then make sure you use this tool. It's by far the simplest tool I use in my keyword research arsenal. That's not to say the others are difficult to use, this one's just the easiest. If you aren't focusing on your site's SEO, then I suppose SEO research and a keyword like this may not suit you, but I believe that every business that has a website should focus on SEO - so a tool like this is a good tool to have.
To get a quick handle on keyword metrics and ideas, this tool really is idea. It is sooooooo much easier to work with than Semrush, which does a lot and is organized, on the whole, rather poorly.
Over the years I have learned that WordTracker's KEI is particularly good at revealing a keyword's relative value.
WordTracker finds related search terms which helps us develop a more comprehensive keyword strategy.
WordTracker also enables practical sorting across columns which helps us select competitive keywords quickly.
We use WordTracker frequently in our first phases of keyword research and have found it to be very solid.
This tool provides us with data to support our recommendations for changes that may need to be made to be successful in the SERPs and is also helpful in explaining our overall strategy to our clients.
I only use WordTracker, rather than the old Google keyword research tool. In my experience, WordTracker is the best keyword analysis tool because it's easy to understand, use, and find the information for which you are looking. I also think WordTracker is the most well known and trusted amongst its competitors
