The `` element is used to provide metadata about an HTML document. According to the HTML specification, a `` element must serve a specific purpose, and that purpose is determined by its attributes. A bare `` tag or one with only a `charset` attribute in the wrong context will trigger this validation error.
There are several valid patterns for `` elements:
- **`name` + `content`**: Standard metadata pairs (e.g., description, viewport, author).
- **`http-equiv` + `content`**: Pragma directives that affect how the browser processes the page.
- **`charset`**: Declares the document's character encoding (only valid once, in the ``).
- **`itemprop` + `content`**: Microdata metadata, which can appear in both `` and ``.
- **`property` + `content`**: Used for Open Graph and RDFa metadata.
When a `` tag doesn't match any of these valid patterns, the validator raises this error. The most common causes are:
1. **Forgetting the `content` attribute** when using `name` or `property`.
2. **Using non-standard attributes** without the required ones (e.g., only specifying a custom attribute).
3. **Placing a `charset` meta in the ``**, where it's not valid.
4. **Typos** in attribute names like `contents` instead of `content`.
This matters for standards compliance and can also affect SEO and social sharing. Search engines and social media crawlers rely on properly formed `` tags to extract page information. Malformed tags may be silently ignored, meaning your metadata won't take effect.
## Examples
### Incorrect: `` with `name` but no `content`
```html
My Page
```
The `` tag is missing its `content` attribute, so the validator reports the error.
### Correct: `` with both `name` and `content`
```html
My Page
```
### Incorrect: `` with `property` but no `content`
```html
My Page
```
### Correct: Open Graph `` with `property` and `content`
```html
My Page
```
### Incorrect: `` with only a non-standard attribute
```html
My Page
```
Here, `value` is not a valid attribute for ``. The correct attribute is `content`.
### Correct: Using `content` instead of `value`
```html
My Page
```
### Incorrect: Bare `` tag with no meaningful attributes
```html
My Page
```
A `` element with no attributes serves no purpose and should be removed entirely.
### Correct: Using `itemprop` in the ``
The `itemprop` attribute allows `` to be used within the `` as part of microdata:
```html
Example Product
```
