In short. Wix rejects duplicate or default tags and requires valid meta or link HTML within its limit of 10 additional tags.
Definition: A meta tag is HTML code containing page information that browsers and search engines can read. As of October 2026, Wix's Additional Tags field rejects duplicate tags, including defaults Wix already creates, and accepts only valid HTML using
<meta>or<link>, within a limit of 10 additional tags.
Key facts
- Wix's troubleshooting guide states that the same meta tag cannot be added twice, including a default tag Wix already creates.
- Wix's additional tags documentation sets a limit of 10 additional tags and restricts this field to
<meta>and<link>elements. - Wix's default SEO settings documentation explains that changing a field in the SEO panel overrides its default value.
How is an existing tag changed?
The first check is whether the tag already exists. Wix's default settings table includes the meta description and social tags such as og:title and og:site_name. These defaults explain why a tag can already exist before any additional tag is entered.
For a title or description change, Wix's title and description instructions use the page's SEO basics panel. The fields are Title tag (title in search results) and Meta description (description in search results). The documented final step is Publish.
For tags listed under Additional Tags, Wix's editing instructions use Pages & Menu, the page's More Actions menu, SEO basics, then Advanced SEO and Additional Tags. The tag's own More Actions menu offers Edit. Hide applies to default meta tags; Delete applies to additional meta tags.
What format does the field accept?
Wix's format guidance requires valid HTML and gives these generic syntax examples:
<meta key="value" another_key="value"/>
<link rel="value" href="value"/>
The attribute names and values above are placeholders from the documentation. A real tag needs the attributes and values required for its purpose. Checking the element type and HTML syntax belongs alongside checking for an existing tag and the 10-tag limit.
For a supported new tag, Wix's adding instructions use + Add New Tag under Additional Tags, followed by the HTML Code field and Apply.
Where does unsupported code go?
Wix's additional tags FAQ directs unsupported tag types to Custom Code. Its Custom Code instructions require a published site with a connected domain.
The dashboard route is Settings, Development & integrations, Custom Code, then + Add Custom Code. The controls allow all pages or specific pages and a placement in the page head or body. For third-party snippets, Wix instructs site owners to follow the provider's placement instructions and contact that provider for technical problems.

FAQ
Can I delete a default tag and add it again?
Wix's additional tags FAQ says you can delete only additional meta tags. For defaults listed in Additional Tags, use the available Edit or Hide control.
Does having fewer than 10 tags rule out a duplicate problem?
No. Wix's troubleshooting guide treats the limit and duplicate restriction separately. You still need to check whether Wix already creates the tag.
