What are common on-page SEO mistakes?

Common on-page SEO mistakes include missing or duplicate title tags, thin content that does not fully answer the search intent, and a lack of internal links connecting related pages on the same site.

Ignoring mobile page speed is another frequent issue, since Google evaluates the mobile version of a page for ranking purposes, and a slow mobile experience directly hurts rankings even if the desktop version loads fine.

Overstuffing content with an exact keyword phrase, rather than writing naturally and covering the topic thoroughly, remains a common mistake despite being outdated advice that can actively backfire under current ranking systems.
