Solution 1

You should explicitly provide a type these properties (name, description, image) belong to.

In Schema.org, everything is a Thing. Thing has many child types, listed under "More specific Types". Start there and choose the most specific type for your content.

For example: WebPage, Article or maybe BlogPosting.

It could look like (using WebPage as example here):

<html itemscope itemtype="http://schema.org/WebPage">

Solution 2

If you use itemprop meta tag in header for your site title, description and so on.

only just add itemscope itemtype="http://schema.org/WebPage" in your html tag.

Usage:

<html itemscope itemtype="http://schema.org/WebPage">

For better SEO I need put some meta on my page like this:

<!-- Schema.org markup for Google+ -->
<meta itemprop="name" content="The Name or Title Here">
<meta itemprop="description" content="This is the page description">
<meta itemprop="image" content="http://www.example.com/image.jpg">

Here is the source.

Then I check this code on Markup Validation Service:

<!DOCTYPE html>
<html>
<head lang="en">
  <meta itemprop="name" content="The Name or Title Here">
  <meta itemprop="description" content="This is the page description">
  <meta itemprop="image" content="http://www.example.com/image.jpg">
  <meta charset="UTF-8">
  <title>My title</title>
</head>
<body>
  My body.
</body>
</html>

Throwing this error:

Line 4, Column 57: The itemprop attribute was specified, but the element is not a property of any item.
 <meta itemprop="name" content="The Name or Title Here">
Line 5, Column 70: The itemprop attribute was specified, but the element is not a property of any item.
 <meta itemprop="description" content="This is the page description">
Line 6, Column 68: The itemprop attribute was specified, but the element is not a property of any item.
 <meta itemprop="image" content="http://www.example.com/image.jpg">

How can I fix this?
