Quick answer
On-page SEO is the practice of optimising a page's content, headings, meta data and internal links so search engines and users can understand it.
What it is
On-page SEO covers everything you control on a single page: title tag, meta description, heading structure, body copy, internal links, images and structured data. It is the foundation of every SEO program.
Why it matters
Search engines read your page to decide what it is about and who it should rank for. Strong on-page SEO makes that decision easy and accurate.
How to use it
- Pick one primary keyword per page and use it in the title, H1 and first paragraph.
- Write a meta description that promises the outcome and includes proof.
- Use a logical heading structure (H1, then H2s, then H3s).
- Add internal links to and from related pages using descriptive anchor text.
- Add FAQ schema for question-shaped content.
Examples
- An e-commerce page adds alt text to every product image and lifts image search traffic by 22%.
- A SaaS landing page tightens its H1 to include the primary keyword and lifts conversion by 11%.
