## **🔍 Overview**

Some websites published through **Website Studio** contain a hidden duplicate H1 tag inside the **index.html** file. This issue is not caused by your content or settings — it is a known platform-level bug that affects published sites. The duplicate H1 tag cannot be seen or removed from within the Website Studio editor, but it is detectable by SEO audit tools, including the built-in Search Atlas SEO audit.

Our engineering team has identified this issue. This article explains the impact of the bug, what you can do right now, and how to get hands-on help if you need it.

## **⚠️ What Is the Impact?**

Having two H1 tags on a single page can negatively affect your site in the following ways:

- **SEO audit failures:** Your site will fail the H1 check in the Search Atlas SEO audit and in third-party tools, even if your visible page content looks correct.
- **Search engine confusion:** Search engines use the H1 tag to understand the primary topic of a page. A duplicate can dilute relevance signals and hurt rankings.
- **Launch blockers:** If you are using an SEO checklist as part of your site launch process, this error may prevent you from confidently publishing.

## **📋 Steps to Take Right Now**

1. **Confirm the duplicate H1 exists.** Run a Search Atlas SEO audit or use a browser extension such as a heading checker to verify there are two H1 tags on your published page. This helps rule out false positives from other tools.
2. **Check that your editable H1 is correct.** Open your project in **Website Studio** and confirm that only one H1 heading appears in your visible page content. If you see two H1 headings in the editor itself, remove the duplicate manually before proceeding.
3. **Republish your site.** After confirming your editable content has only one H1, republish your site using the publish option available in Website Studio.
4. **Re-run the SEO audit.** Check whether the duplicate H1 error is still present after republishing. If it is, the hidden tag in the generated **index.html** is the cause, and the issue exists at the platform level rather than in your editable content.
5. **Contact support for assistance.** If the error persists after republishing, reach out to our team with your project name and the SEO audit report showing the duplicate H1 error so we can investigate further.
