The length of your H1 tag seems to be outside the recommended range. Ideally, an H1 tag should be between 10 and 255 characters, including spaces, and remember to use only one H1 tag per page.
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.
