Specifies the International Standard Book Number (ISBN) of a book. Used within Open Graph tags to classify and uniquely identify books, improving the sharing experience on social media platforms.

Code Examples

<meta property="book:isbn" content="978-3-16-148410-0" />
Specifies the book's ISBN correctly with a 13-digit format, ensuring it can be uniquely identified and found easily on the web.
<meta property="book:isbn" content="3-16-148410-X" />
Uses a 10-digit ISBN format, which, while valid, is less preferable than the 13-digit format due to potential ambiguities and compatibility issues.
<meta property="book:isbn" content="978-3-16-148410-X" />
Specified an incorrect ISBN format, using an 'X' in a 13-digit ISBN, demonstrating the importance of careful verification.

Recommendations

  • Use the 13-digit ISBN format
    Prefer using the 13-digit ISBN format over the 10-digit to reduce ambiguities and ensure broader compatibility and recognition across platforms.
  • Verify the ISBN
    Always verify the ISBN for accuracy before using it in your meta tag. Incorrect or mistyped ISBNs can lead to misidentification or failed searches for your book on social platforms.
