HTML Checking for Large Sites

Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.

Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

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="">
  Price: $<span itemprop="price">1.00</span>
  <meta itemprop="priceCurrency" content="USD" />

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">
