我怀疑正确使用架构ImageObject.
我有一个小图像和一个链接,以更大的尺寸查看它,但我不知道这三种形式是否正确.
<span itemprop='image' itemscope itemtype='http://schema.org/ImageObject'>
<a href='big_1280x720.jpg' itemprop='contentUrl'><img src='small_90x60.jpg' itemprop='image'></a>
</span>
<span itemprop='image' itemscope itemtype='http://schema.org/ImageObject'>
<a href='big_1280x720.jpg' itemprop='image'><img src='small_90x60.jpg' itemprop='thumbnailUrl'></a>
</span>
<span itemprop='image' itemscope itemtype='http://schema.org/ImageObject'>
<a href='big_1280x720.jpg' itemprop='contentUrl'><img src='small_90x60.jpg' itemprop='thumbnailUrl'></a>
</span>
