To do keyword research, you need to understand what your audience is searching for and how that relates to your business. There are a few different ways to find out this information.
One way is to use keyword research tools like Google AdWords Keyword Planner and Semrush Keyword Magic Tool. These tools will help you understand how often certain keywords are being searched for and how much competition there is for them.
Another way to do keyword research is to look at your competitor's websites and see what keywords they are targeting. You can also use Google Analytics to see what keywords people are using to find your website.
Once you have a list of keywords, you need to start optimizing your website for them. This means using them in your titles, tags, and descriptions. You should also create content that is optimized for your keywords. This will help your website rank higher in search engines for those keywords and get more traffic.
