Need a layman's definition/analogy of the difference between schema and structured data
-
I'm currently writing a blog post about schema. However I want to set the record straight that schema is not exactly the same as structured data, although both are often used interchangeably. I understand this schema.org is a vocabulary of global identifiers for properties and things. Structured data is what Google officially stated as "a standard way to annotate your content so machines can understand it..."
Does anybody know of a good analogy to compare the two?
Thanks!

Hi Rosemary, Dave here.
I like to think of it like our addressing system. Because we all use the same system and format for our addresses on an envelope we don't need a code to tell us but as you know ... everyone displays their product information and other data differently on a page. Because of that the engines can have difficulty telling what bit of data is what. Is "blue" the color of the product, the color of the screen or simply used on the page in a "Don't feel blue ... buy XYZ !"
Structured data, as Matt well-noted, is just an idea really of matching information with what it means. Like saying "blue" = "product color".
Of course, that's all well-and-good but we can all build our own systems and many have been. If we're all using different systems then nothing makes sense so folks got together and created Schema.org simply as a body that could help create a standard. Like saying, "on an envelop you put the name first, then the address, then the city, then the state, then the zip code". If we put things on the envelop differently things would get messy so Schema basically gives us the instruction on how to pass information across. Schema isn't the idea or even the data, it's the instructions on how to tell Google what specific data means.
Clear as mud?

Well, let's see. Structured data in this sense comes down to a method of labelling elements of your site in order to clarify what they are for search engine crawlers, microdata is a form of structured data that works in HTML5, and Schema is a standard for microdata. So Schema is microdata is structured data. All Schema (in this use) is structured data, but not all structured data is Schema.
Maybe something like, if structured data represents all the team sports in the world, and microdata represents every game intended to be played on a football pitch, then Schema may be the Laws of the Game—the standard rules for international soccer.
Also, go Seattle Sounders!

Yes, thank you. However I'm looking for a simple layman's analogy. Most of the blog post readers are not going to be able to comprehend the technical aspects.

Hi Rosemary! There's actually a pretty decent explanation here: https://moz.com/learn/seo/schema-structured-data
Structured data is a system of pairing a name with a value that helps search engines categorize and index your content. Microdata is one form of structured data that works with HTML5. Schema.org is a project that provides a particular set of agreed-upon definitions for microdata tags.
Does that make sense?

Structured data: Product vs auto rental schema?
Hi mozzers, If you are rental company, is it useful to add both the product and auto rental schemas or auto rental schema on its own should just be enough? Finally, on the auto rental schema, you have to add an address. Could we just add a city instead of an entire address and avoid receiving a warning message on the strutured data testing tool? Thank you.

Can subdomains hurt your primary domain's SEO?
Our primary website https://domain.com has a subdomain https://subDomain.domain.com and on that subdomain we have a jive-hosted community, with a few links to and fro. In GA they are set up as different properties but there are many SEO issues in the jive-hosted site, in which many different people can create content, delete content, comment, etc. There are issues related to how jive structures content, broken links, etc. My question is this: Aside from the SEO issues with the subdomain, can the performance of that subdomain negatively impact the SEO performance and rank of the primary domain? I've heard and read conflicting reports about this and it would be nice to hear from the MOZ community about options to resolve such issues if they exist. Thanks.

A client rebranded a few years ago and doesn't want to be associated with it's old brand name. He wishes not to appear when the old brand is searched in Google, is there something we can do?
The problem is there was redirection between the old branded site and the new one, and now when you type in the name of the old brand, the new one comes up. I have desperately tried to convince this client there is nothing we can do about it, dozens of news articles crop up with the two brands together as this was a hot topic a few years ago, but just in case I missed something I thought I'd ask the community of experts here on Moz. An example for this would be Tyco Healthcare that became covidien in 2007. When you type tyco healthcare, covidien crops up here and there. Any ideas? Thanks!

Something happened within the last 2 weeks on our WordPress-hosted site that created "duplicates" by counting www.company.com/example and company.com/example (without the 'www.') as separate pages. Any idea what could have happened, and how to fix it?
Our website is running through WordPress. We've been running Moz for over a month now. Only recently, within the past 2 weeks, have we been alerted to over 100 duplicate pages. It appears something happened that created a duplicate of every single page on our site; "www.company.com/example" and "company.com/example." Again, according to our MOZ, this is a recent issue. I'm almost certain that prior to a couple of weeks ago, there existed both forms of the URL that directed to the same page without be counting as a duplicate. Thanks for you help!

Is there any SEO advantage to sharing links on twitter using google's url shortener goo.gl/
Hi is there any advantage to using <cite class="vurls">goo.gl/</cite> to shorten a URL for Twitter instead of other ones? I had a thought that <cite class="vurls">goo.gl/</cite> might allow google to track click throughs and hence judge popularity.

What's the best method for segmenting HTML sitemap?
Hello all, I was wondering if anyone can help me. Currently I'm trying to set up a HTML sitemap for our website and am having trouble with the 500+ pages of content under each category. How do you segment your HTML sitemap in a case like this, keeping in mind the less than 100 links per page rule? For example, http://www.careerbliss.com/salary/ allows our users to search salaries under company, job title, and location. You can imagine how many thousands of pages we need to represent. Any help will be greatly appreciated! Cheers! Reyna
