# On-Page SEO

On-Page SEO — all title, meta, content, internal link, image, and technical optimizations made directly on a web page itself.

**On-Page SEO (page-level SEO)** covers all optimizations made _directly on_ a web page so it can perform better in search engines.

The core components of On-Page SEO:

- Title tag (title) and meta description
- Heading hierarchy from H1 to H6
- Content quality, depth, and keyword usage
- URL structure and readability
- Image optimization (alt text, file size, format)
- Internal linking (internal linking)
- Schema markup and Structured Data

It should be considered together with Off-Page SEO (backlinks, brand mentions); however, while you do not have full control over Off-Page, On-Page is completely under your control. For that reason, in an SEO project, On-Page is built on a solid foundation first, and then authority-building work begins.

**Tip:** Apply your On-Page checklist before publishing every new page. Even a single title tag adjustment can sometimes create noticeable changes in rankings.
