The short answer

On page SEO is optimising the things on your own pages: content, titles, headings, images and internal links, so they are relevant and easy to understand. Off page SEO is what happens elsewhere, mainly links from other sites. Technical SEO is how a site is crawled, indexed and served. A SERP is the page of results shown after a search, and organic search is the unpaid listings earned through relevance, which on page SEO aims to improve.

What on page SEO is, and how it differs from off page and technical

On page SEO is optimising the things on your own pages, such as content, titles, headings, images and internal links, so they are relevant, useful and easy for search engines to understand, and it is the part you directly control. Because it covers what is actually on the page, on page SEO is foundational to how well a page can perform. On page SEO is what you do on your own pages, while off page SEO is what happens elsewhere, mainly links and mentions from other sites. They work together; because on page covers your content and off page covers your reputation, a strong strategy needs both rather than one alone. On page SEO focuses on content and how it is presented, while technical SEO focuses on how a site is crawled, indexed and served. The two overlap but differ in emphasis; because on page is about relevance and quality and technical is about foundations, both are needed, which is why our technical SEO guide sits alongside this one.

Optimisation, SERPs and organic search

What optimisation involves, and SERPs and organic search

On page SEO optimisation is the ongoing work of improving those on-page elements so each page clearly matches what people are searching for. A search engine results page, or SERP, is the page of results shown after someone searches, including organic listings, ads and features like snippets, and it is where visibility happens. Because your titles and descriptions appear here, on page work directly affects how you show up on the SERP. Organic search is the unpaid listings on a results page that are earned through relevance and quality rather than paid for, and it is what SEO aims to improve. Because organic results are driven by how well pages match a query, good on page SEO is central to earning organic visibility, starting with your title tags and meta data.
