I have ZERO background in SEO and am entirely self-taught. My website serves a niche market and is a side job, so not my primary focus. KWFinder was fantastic for easy explanations of why things mattered (i.e. CPC, KD) and free to try. Also, when I did have questions, I got a really quick email chat reply (always lovely.) I cannot speak to how ideal this is for someone more advanced in the industry, but for a small and low budget project it has been perfect.
Ubersuggest is well suited for people who needs to conduct a basic keyword research to rank content in google. Whoever, the tool can be limited for people with more expertise and SEO knowledge. Nevertheless, having more free tools than other similar platforms, I recommend it to those who are starting in SEO.
Ubersuggest is relatively easy to navigate, even for beginners. The layout is simple and intuitive, which makes it accessible for users with little to no SEO experience. It doesn’t have the overwhelming complexity of tools like Ahrefs or SEMrush. Users can start using the tool right away without needing extensive onboarding. You can quickly enter a domain, run a site audit, or perform keyword research without having to dig through tutorials or guides.
They have a lot of information on their website, and also training and contact options in the tool. So you can learn on the go while trying the tool. And if you are stuck, support reacts really fast--sometimes the same day, sometimes the next day due to time zones. Payment is easy and easy to cancel.
All these tools are extremely powerful, and keyword research is just one component of the tools. That said, keyword research using KWFinder, for me, has been most enjoyable out of all of these. It's mostly because of how easy it is to use. The UI is nice to look at, it's just a fun and quick app to use.
Very good and easy for those starting out. There are other more robust and better featured products, but they are more expensive. The others also have phone support options, which I have found very useful in the past. For larger companies I would probably look at someting else, but Ubersuggest is good for most SMBs
