# Only one H1 tag in content (Pro)

This feature requires the Pro version of the PublishPress Checklists plugin.

With the Pro version of the [PublishPress Checklists](https://publishpress.com/links/checklists) plugin, you can specify that there is only a single H1 tag in your content. This is important for accessibility and also H1. There should only ever be a single H1 tag on content pages.

If too many H1 tags are present, you can choose to show a warning, or prevent the post from being published.

- Click the "Accessibility" tab. The screenshot below shows the “Only one H1 tag in content” option.
- You can choose from "Disabled, Recommended, or Required" options.
- You can choose "Who can ignore this task?"
