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.
Semrush's content and page optimisation tool is quite poor; it's not in the same bracket as Surfer. Frase is a good alternative from a cost perspective (if not paying the AI writing functions), it's cheaper, and Frase's keyword/topic heatmaps are quite unique. Sufer has a better UI and a shorter learning curve. It has an advantage in that it offers internal linking recommendations, which Frase lacks. Surfer also has limited competitor analysis (backlinks and page speed), which Frase does not. Both tools allow you to choose the number of competitors on the SERPS
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
