Itemscope and itemprop at same level

阅读更多关于 Itemscope and itemprop at same level

问题 I have a link that looks like this: <a href="//href" itemscope itemtype="http://schema.org/Product"> <img src="src" itemprop="image"> </a> I'd like to put itemprop="url" in the <a> tag, but it contains the itemscope for that product. Can I put that at the same level as itemtype= ? Or, do I either need to wrap the whole thing in a div to make it work, or use a <meta> tag for the itemprop="url" microdata? Thanks! 回答1: You can have itemprop and itemscope on the same element, but it will mean

Implicity of web page structure in Schema.org

阅读更多关于 Implicity of web page structure in Schema.org

问题 After reading thousand of posts, questions, blog articles and opinions, I'm still a bit confused about how to markup a web page with microdata. If the main purpose of microdata is to help search engine to better understand the content of a web page (and web page is assumed implicitly), is it correct to start with itemtype Webpage in the body element, and then continue to markup the rest of nested elements defining which is the main entity, or is it better to start with an itemtype that is

Link `isRelated` schema.org to parent `Product` when not contained in child element

阅读更多关于 Link `isRelated` schema.org to parent `Product` when not contained in child element

I'm trying to indicate multiple related products on a product page using schema.org microdata. But the child products are orphaned because they are not contained in the parent div. I tried using itemref but I must be using it incorrectly or it must be the wrong solution. ALSO, I cannot easily create a wrapper div or use the body element to create the parent. My ideal solution would be one that leaves the page structure as-is, and somehow links the "child product" divs to the parent. I thought itemref would do that, but it doesn't appear to be working. Here is example HTML. <div id="main

Omitting price property for sold products?

阅读更多关于 Omitting price property for sold products?

I'm adding Schema.org (using Microdata) to a product page. My client wants the price omitted for sold products - she doesn't want anyone to be able to see the price of sold products. However this was showing up as an error in the Microdata for 'price': check page in Google SDTT Obviously the average user will still not be able to see the price, but it's used by Google Shopping so might show up. Should I just put a price of 0? It’s perfectly fine to have an Offer without a price . If Google’s Structured Data Testing Tool complains, it does not necessarily mean that you have an error in your

What is the difference between metadata & microdata?

阅读更多关于 What is the difference between metadata & microdata?

I am quite puzzled with these two terminologies. I know the basic meaning of metadata is "data about the data" . Microdata means the webpages are now more accessible to the search engines . But what separates these two terms? unor Microdata is the name of a specific technology, metadata is a generic term. Metadata is, like you explain, data about data. We’d typically want this metadata to be machine-readable/-understandable, so that search engines and other consumers can make use of it. In the typical sense, metadata is data about the whole document (e.g., who wrote it, when it was published

Separate rich snippet scopes for the same item

阅读更多关于 Separate rich snippet scopes for the same item

问题 I am creating rich snippets for my webshop. One of the itemtypes I use is the "Organization" type. The problem with this is that I have specified the Organisation name and the image in the header of my webshop and the address in the footer. In between is the rest of the webshop with all it's products, reviews etc. When I test my rich snippets with http://www.google.nl/webmasters/tools/richsnippets, I get two separate Organisations instead of one. Is there a way to combine my two scopes to

Product size: width, height and depth

阅读更多关于 Product size: width, height and depth

I'm using schema.org definition to represent a product. I have a doubt about product size: should I specify the unit of measure in the field?

I am pretty new to Microdata. I have a HTML string with Microdata. I am trying to figure out if it's possible to extract the required information dynamically using Microdata with JS or jQuery.
