When I used to work for a digital marketing agency, one of my responsibilities was to write blog content for our clients. To do this, some SEO research was required because we wanted to improve organic traffic. So, I did keyword research to figure out what the target audience wanted to read about. I was able to use the keywords to brainstorm topic ideas and pillar pages, while also creating a list of keywords we could target. That's why Google ads keyword planner is an important tool for marketers.
