What is the difference between technical SEO and on-page SEO?

Technical SEO covers whether search engines can crawl, load, and index a page properly, speed, mobile responsiveness, sitemaps, structured data. On-page SEO covers the content elements within a page itself: titles, headers, meta descriptions, and the body copy.

The distinction matters because they require different skills. Technical SEO often needs development or code changes, while on-page SEO is mostly a writing and structuring task anyone can learn.

Both need attention together. A well-written page on a technically broken site underperforms, just as a technically perfect site with weak content will not rank for competitive terms.

An SEO automation platform handles the on-page half directly, writing and structuring every published page.
