# book:author

Links a book to an author profile. The value is a URL, and you can repeat the property for multiple authors.

## Code examples

Good example

```
<meta property="book:author" content="https://example.com/authors/margaret-atwood">
```

Points to the author’s profile page.

Good example

```
<meta property="book:author" content="https://example.com/authors/octavia-butler">
```

Another valid profile URL.

Avoid this example

```
<meta property="book:author" content="Margaret Atwood">
```

A plain name is not the profile URL expected by the protocol.

Avoid this example

```
<meta property="book:author" content="">
```

An empty value identifies no author.

## Recommendations

- 01 Link to a Profile Use the canonical URL of a page that describes the author. Open Graph defines this value as a profile object, not a name.
- 02 Repeat for Coauthors Add one book:author property per author.
- 03 Use a Stable URL Prefer a permanent author page over a search result or temporary campaign URL.
