JSON-LD and Microdata on the same page?

阅读更多关于 JSON-LD and Microdata on the same page?

I have both Micro Data and JSON-LD on my e-commerce product pages, describing the same thing (products in my case). For reasons beyond the scope of this question, I cannot remove either of the two formats. I am wondering: Is this a problem for Google? The structured data testing tool does display two items (products) instead of one. If one property, let's say the name of the product, is slightly different between the two formats, would any of the two formats, for example, JSON-LD take priority? unor The problem is that a consumer would think that different things are described (or more

Breadcrumb with Schema.org not showing in Google Rich Snippets testing tool

阅读更多关于 Breadcrumb with Schema.org not showing in Google Rich Snippets testing tool

问题 I have tested the Schema.org breadcrumb example with Google Rich Snippets testing tool. <div itemprop="breadcrumb"> <a href="category/books.html">Books</a> > <a href="category/books-literature.html">Literature & Fiction</a> > <a href="category/books-classics">Classics</a> </div> The result is that it is not recognized by the tool. So, is there a bug or is there a syntax problem? If so, what is the correct syntax? 回答1: Your question is a bit the same with this one How to implement schema.org

The correct approach to markup “keywords” of a blog post by using HTML5 and Microdata?

阅读更多关于 The correct approach to markup “keywords” of a blog post by using HTML5 and Microdata?

问题 The keywords property from Schema.org, as it being in plural form suggests, seems to imply its value should be a line of comma-separated text . Like the following example: <p itemprop="keywords">lorem, ipsum, dolor, sit, amet</p> That reminds me of the <meta name="keywords" content="lorem, ipsum, dolor, sit, amet"> tag we used to put within <head></head> for SEO reason. However, from semantics' perspective, I think the above example is incorrect because keywords should be a list of words .

HTML5 semantic markup for blog post tags and categories

阅读更多关于 HTML5 semantic markup for blog post tags and categories

问题 Many blogs use the concept of "tags" and "categories" to add metadata to a post. What is the best practice for semantic markup for this information, such that a machine reading the blog post could easily identify the tags? Currently I add "tag" to the rel attribute on the link, e.g. <a rel="tag" class="tag" href="/tags.html#site-configuration">#site-configuration</a> I suppose one could use Dublin Core's html format for keyword: <meta name = "DC.Subject" content = "site-configuration"> and

HTML 5 Page without main <header>?

阅读更多关于 HTML 5 Page without main ?

Is it bad to nave no <header> ? I have this basic structure but I am thinking about wrapping a header arround everything between the body start and the content because the header has also this nice shema.org markup attached. Good Idea? Just because sometimes the header is not there but the navbars actually contain the brandname and are sort of headers themseves. if I do this how should I markup whats the <header> right now? A section inside a header is not valid right? Just a normal <div> I guess. <body> <div class="nav1"><h1>brandname</h1><nav>...</nav></div> <header><h1>brandname</h1><p

Schema.org NewsArticle: invalid value for logo property

阅读更多关于 Schema.org NewsArticle: invalid value for logo property

I try to markup a little section in my code as NewsArticle but I can't get it to validate. If I do this <div itemscope itemprop="publisher" itemtype="https://schema.org/Organization"> <span itemprop="name">My Company</span> </div> the validator complains that there is no logo . And if I add a logo like this <div itemscope itemprop="publisher" itemtype="https://schema.org/Organization"> <img itemprop="logo" src="https://www.mysite.de/resources/assets/71/small/my_logo_web.png" /> <span itemprop="name">My Company</span> </div> the validator complains that the attribute contains an invalid value.

Microdata or JSON-LD? I'm confused

阅读更多关于 Microdata or JSON-LD? I'm confused

问题 I haven't found a clear and updated answer, even after googling for a few hours, so here it goes: I am aware of the advantages and disadvantages of both Microdata and JSON-LD. I also know that Microdata was dropped from W3C (and consequently from the browsers' API). What I'm not sure about is that how it will affect any site where Microdata is used specifically for SEO purpose. Does Google support JSON-LD for SERPs? What format does it recommend to use? I am looking for updated answers - not

Schema.org/Microdata markup for list of recent posts without providing “author” / “publisher”?

阅读更多关于 Schema.org/Microdata markup for list of recent posts without providing “author” / “publisher”?

The following code shows a list of links to recent posts on an experimental blog site I am playing with. The problem is that this fails Google's Structured Data Testing Tool because it is missing required items such as author and publisher . But I don't want to show these for recent posts and I don't want to show them for every blog post either. What should I do? Get rid of the structured data? Put the required stuff in and hide it with CSS? Or leave as is? <section> <header> <h4 class="h4-padding">Recent Posts</h4> </header> <ul> <li> <article itemprop="blogPost" itemscope itemtype="http:/

Why does Google Testing Tool use the “id” attribute to generate a URL for the Microdata item?

阅读更多关于 Why does Google Testing Tool use the “id” attribute to generate a URL for the Microdata item?

I'm using some Microdata to describe a blog post, and I'm surprised by the value return for Schema.org’s BlogPosting by the Google Developers Testing Tool. I would have expected it to be the itemprop url , not a merge of the website URL and the item id . Am I doing something wrong, or is it only a Google display issue? <div itemscope="itemscope" itemprop="blogPost" itemtype="http://schema.org/BlogPosting" id="foobar"> <a itemprop="url" href="/realone">real</a> </div> Value returned by https://developers.google.com/structured-data/testing-tool/ : BlogPosting: http://www.example.com/foobar url:
