I have a SAAS product, and I need to do SEO. My SAAS is a drag-and-drop web builder with easy code customization, but it's only suitable for people who know how to code—those without coding knowledge can't use it. I searched for keywords related to my topic and analyzed over 1,000 keywords, but they all basically have zero search volume. What should I do? P.S. I'm new to SEO.
