What Is the Difference Between Technical SEO and On-Page SEO?

Technical SEO covers site-wide infrastructure: crawlability, page speed, mobile usability, and structured data, the kind of work a developer usually handles. On-page SEO covers decisions made on individual pages: the content itself, titles, headings, and internal links, work usually handled by a writer or marketer instead.

The two need to work together. A technically healthy site with weak content still will not rank for competitive terms, and beautifully written content on a slow, poorly structured site will underperform regardless of how good the writing underneath it actually is.

A SEO content writing tool handles the on-page, content side; technical fixes remain a separate, usually developer-led task.
