HTML issues tagged as microdata.
A <meta>
element without a itemprop
or property
attributes has been found in an unexpected place.
While the <meta>
element is commonly used within the <head>
section of the document, it can also be used within the <body>
section, for example in the context of defining microdata, as in this example:
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
Price: $<span itemprop="price">1.00</span>
<meta itemprop="priceCurrency" content="USD" />
</div>
When used within the <body>
section, the <meta>
element is required to have a itemprop
or property
, and a content
attribute, and it can’t have a http-equiv
or charset
attribute.
A common cause for this issue is including a <meta>
element that was intended for the <head>
section (for example one containing a http-equiv
attribute in the <body>
, for example:
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<form>
...
</form>

An itemprop
attribute has been found in the document, but it cannot be associated to any item. Most probable cause is the lack of an itemscope
attribute defining an item.
Microdata allows nested groups of properties, which must be scoped to the item they belong to, as in this example:
<div itemscope>
<p>My name is <span itemprop="name">Liza</span> and I'm <span itemprop="age">48</span> years old.</p>
</div>
