On-page SEO (also known as “on-site SEO”) is the practice of optimizing webpage content for search engines, AI platforms and LLMs, and users.
Common on-page SEO practices include optimizing title tags, content, internal links, URLs, and other ranking factors.
This is different from off-page SEO, which is optimizing for signals that happen off of your website.
Examples of off-page SEO tactics include building backlinks, social media marketing, guest posting, and digital PR.
