Your page does not include an H1 tag.

The H1 tag in HTML is the main headline users see first when a page loads. It conveys the page's topic, enticing visitors to read further. 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.
  • Limit to one H1 tag per page.
  • Keep H1 tags short and concise.
  • Structure headings hierarchically.
  • Include your main keyword.
  • Ensure H1 tags are engaging.
