一篇博客/文章有多个标签时,如何添加Facebook Open Graph数据?
这似乎是最合适的方法。然而,在Facebook调试器中报告说它不正确:
<meta property = "article: tag" content = "advocate, charity, crowdfunding, Healthcare, hospitals, Medical Bills, Medicare, negotiate, uninsured" >
像这样添加相同的内容似乎是正确的,但看起来很荒谬:
<meta property="article:tag" content="advocate" />
<meta property="article:tag" content="charity" />
<meta property="article:tag" content="crowdfunding" />
<meta property="article:tag" content="Healthcare" />
<meta property="article:tag" content="hospitals" />
<meta property="article:tag" content="Medical Bills" />
<meta property="article:tag" content="Medicare" />
<meta property="article:tag" content="negotiate" />
<meta property="article:tag" content="uninsured" />
怎么才是正确的方法?有没有更“优化”的写法?
