H1 tags are crucial for SEO, user experience, and accessibility. They distinguish the main title on a webpage, aiding search engines and users in understanding the content.

Here are best practices for H1 tags

  • Use H1 tags for page titles.

  • Keep H1 tags short and concise.
  • Structure headings hierarchically.
  • Include your main keyword.
