Keyword placement is only one part of on-page SEO. A page also needs a logical heading hierarchy, useful content, descriptive URLs, relevant internal links, and a good user experience.
I usually recommend starting with the page's search intent, then checking whether the title, H1, introduction, and main sections address that intent clearly. Images should have descriptive alt text where appropriate, and unnecessary scripts or oversized images should be reviewed if they affect loading speed.
For SEO professionals here, what is your process for balancing keyword relevance with natural, readable content?
