在搜索引擎优化方面...
最好将方案放在包含所有链接的父级上吗?
<nav itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</nav>
...或者每个链接都应该被视为它自己的元素?
<nav>
<span itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement">
<a itemprop="url" href="#">
<span itemprop="name">Link 1</span>
</a>
</span>
<span itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement">
<a itemprop="url" href="#">
<span itemprop="name">Link 2</span>
</a>
</span>
<span itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement">
<a itemprop="url" href="#">
<span itemprop="name">Link 3</span>
</a>
</span>
</nav>
