How to Create SEO-Optimized Content Business Websites?

Hi all,

I’m trying to improve the SEO of my website through content, but I’m not sure where to start. I know content needs to be engaging, but how do I also make it SEO-friendly? What are the key elements to focus on—keyword research, meta tags, internal linking?

I’ve heard conflicting advice on how much keyword density matters, and whether long-form content is always better. Any tips or examples of great content that has worked for your website would be much appreciated!
