Improved SEO: Proper use of header tags helps search engines better understand the content and relevance of different sections on a webpage, potentially improving search rankings.

Enhanced readability: Header tags make content more scannable and readable for users, allowing them to quickly grasp the main topics and structure of a page.

Accessibility benefits: Clear headings provided by header tags improve accessibility for users who rely on screen readers or navigate web pages using keyboard shortcuts.

Semantic markup: Header tags contribute to the semantic structure of HTML documents, aiding in the interpretation and organization of content by browsers and assistive technologies.

Overuse and misuse: Excessive or inappropriate use of header tags can lead to confusion and dilution of the page's semantic structure, negatively impacting user experience and SEO.

Styling limitations: While header tags provide structural markup, their default styling may not always align with the design requirements of a webpage, requiring additional CSS customization.

Impact on visual hierarchy: Improperly nested or inconsistently styled header tags can disrupt the visual hierarchy of a page, making it harder for users to navigate and understand the content.

SEO penalties: Incorrect implementation of header tags, such as using multiple h1 tags or keyword stuffing, can result in SEO penalties from search engines, affecting the page's ranking and visibility.
