Welcome, Jennie. SEO is a great marketing skill to learn. Start with the basics: how search engines work, keyword research, and on-page SEO. HubSpot Academy has a free SEO course that’s a good starting point. Hubspot has a great content marketing course in the HubSpot Academy and their digital marketing course covers a few topics involving SEO as well.
If you’re looking for hands-on practice, try optimizing a blog post or a website page. Test things out and track results. SEO takes time, but the more you work on it, the better you’ll get. Doing hands-on work was the fastest path I took to learning SEO.
