What is on-page SEO?

On-page SEO is the practice of optimizing the elements within a page itself, page titles, header tags, meta descriptions, image alt text, and the body content, to help it rank for target keywords.

It differs from off-page SEO, which relies on external signals like backlinks, and technical SEO, which covers crawlability and speed rather than the content on the page.

Effective on-page SEO starts with matching the page's content to real search intent, then structuring it clearly with a strong title and header hierarchy that makes both readers and search engines understand it quickly.

An SEO automation platform handles this structuring automatically for every page it publishes.
