I was trying to add microformats as following to my webpage:
<div itemscope itemtype="http://schema.org/Product">
<span itemprop="brand">Company Name</span>
<span itemprop="name">Product Name</span>
<span itemprop="description">Product Description</span>
Product #: <span itemprop="sku">12345</span>
</div>
I thought this microformat will only show up in a google search result page. But after adding it, those information became visible on my webpage, and not in a good shape.
Is there something wrong? Or should I use display:none to make it invisible on my webpage?
