On-page SEO is everything you do directly on your pages to help Google understand your content. It includes writing strong titles, using headings correctly, organizing your text clearly, and placing keywords naturally.
Good on-page SEO makes your page readable for both humans and search engines. If your content is helpful and well structured, Google is more likely to reward it with higher visibility. Simple improvements like using one clear H1 heading, breaking content into sections, and adding internal links can make a meaningful difference.
