SEO tools are used to help you optimize your website for search engines. The purpose of using these tools is to help you rank higher in search engines to get more traffic. For example, you can be searching for a new job, and instead of doing a Google search, you use a tool like the H-super tools keyword research tool that will give you a list of keywords related to your search in a long list that you can then narrow down and apply to your job posting. This saves time and allows you to target the right audience.
