Ads outside body tags are a common problem for many website owners. They appear when ad scripts or codes are placed outside the <body> element in HTML. This issue is often triggered by plugins, especially on platforms like Magento, WordPress, or Shopify. While these tools add functionality, they can also introduce HTML validation errors.
Improper ad placements affect more than just design. They lead to wrong HTML code, impact user experience, and create HTML SEO issues. Consequently, if you’re wondering how to fix HTML errors, you’re in the right place. Above all, fixing them improves site health.
Why Ads Outside Body Tags Cause HTML Errors
One major reason for ads outside body tags is poor plugin design. For example, developers sometimes forget to respect the HTML form structure best practices. When ads are inserted before the <html> tag or after the closing </body>, HTML validation error codes appear.
Additionally, third-party ad networks often use scripts with ads outside body tag attributes. These scripts may load late or asynchronously, disrupting the layout. Consequently, this causes HTML validation errors and slows down your page.
To make matters worse, these errors are hard to find manually. Still, you can use tools like W3C Validator to detect them. Moreover, SEO tools can perform HTML SEO issues checks that highlight the problem quickly. In short, prevention is easier than repair.
How to Detect Ads Outside Body Tags in HTML
To find these issues, start with a basic HTML validation errors check. Use tools like:
-
Chrome DevTools (Inspect → Elements)
-
SEO audit tools like Ahrefs, SEMrush, or Screaming Frog
Look for HTML validation error codes like:
“Element script not allowed as child of element html in this context.”
If you see messages like these, then ads outside body tags are likely the culprit. This usually means some wrong HTML code is present. As a result, search engines may fail to index pages correctly.
Besides, if your site uses a CMS with many plugins, deactivate them one by one. Through this process, you can isolate the plugin that causes the ads outside body tag in HTML. Likewise, update outdated plugins regularly.
How to Fix Ads Outside Body Tags Errors
Fixing ads outside body tags is easier than it seems. However, it requires patience and a step-by-step approach. Let’s walk through how to fix HTML errors like these:
-
Identify the plugin or theme injecting the ad.
Checkheader.phpandfooter.phpif you’re using WordPress. -

<html>or below</body>.
These scripts are not valid based on HTML form structure best practices. -
Reposition ads inside the

This is the only safe and SEO-friendly area for them. -
Use proper attributes and async/defer loading where possible.
Avoid ads outside body tag attributes that modify the DOM unpredictably. -

That way, you’ll know right away if HTML validation errors occurred.
