Community Reversing Diabetes - sharing during the journey

I was busy helping my college friends plan a community event when my cousin asked me why his business website was getting visits but very few inquiries. After reading the pages, I felt the content was not clear enough to keep people interested. While looking for better ideas, I found useful writing methods from Kamil Baber about content strategy, SEO blog writing, and website copy that speaks simply to readers. Has anyone here improved search rankings, website traffic, and customer trust by using better content planning and publishing useful articles on a regular basis?
