Among its seemingly never ending suite of tools, Semrush has a hidden gem in its Topic Research Tool. I say ‘hidden’ because I have talked to a lot of Semrush users, even some longtime ones, who had no idea it existed.
Not only is it great for generating topic ideas, but it can also be a great way to gauge how well a competing website is covering a topic. In other words, you can get a quick glance of their topical authority and see where you might need to catch up.
