Benefits/drawbacks to different Schema markup languages (ie. JSON-LD, Microdata, RDFa)
-
Just a question (or questions) I have wondered about. What's the difference, besides the actual encoding, between the three? Why have three? Why not just the one? Seems to me that Microdata is the easiest, but maybe I am wrong. Is there a reason to use one versus another? I have not found anything explaining this on schema.org - I suppose this is just a discussion versus getting one right or wrong answer. I am just curious of the opinions of people in the SEO MOZ community. Unless of course there is one answer. I'll take that too.

Great, Peter. Thanks for the answers. I now understand the difference. Much appreciated.

That's right. JSON-LD doesn't require change of HTML compared with Microdata and RDFa. And this is one of answers why JSON-LD is beautiful. Second is because you can make changes in JSON-LD without touching HTML. Like adding new fields, parameters, etc.
About placing. I think that this can be just on home page. Placing in each page is pure rich snippet spam.

Hi Peter,
Thanks for the answer. So, as I understand it, and keep in mind this is coming from someone that is not very code-savvy, with JSON-LD, one could put the script anywhere in the HTML, the header, the body, the footer, etc. and it won't show up on the actual page, but the search engine will be able to read it. This implies that no changing or tweaking of the actual HTML is necessary, no messing around with 's or
's like you would with Microdata or RDFa, correct?
A follow up question, if I may, how would you implement something like a "local business" schema with JSON, would you put the script on every page, in the footer perhaps? Or would you just put it on the home page? Does it matter?
Thanks

So far we have Microdata, RDFa and JSON-LD.
I'll cover Microdata and RDFa in same because they're similar. So they both are addition to HTML attributes indicating what Schema.org field names correspond with what user-visible text on the page. Works perfect but need lot of developer work and designer changes. Because both backend (admin interface) and frontend (HTML) must be changed. And there are many issues that can be messed - incorrect implementation, "rich snippet spam", software bugs, etc. Look easy as 1-2-3 but in reality it's pain (PIA) for implementation and support. Example - only product implementation require in backend least 10 edit boxes if they're manual filled.
JSON-LD - it's relative new protocol based on Schema.org. The main benefit is that you split representation layer (HTML) from semantic layer (JSON-LD). In prev. formats - they're same and linked each other. Now they're split. This give you much more freedom than before. You can place HTML data whatever you wish and just add hidden JSON in head or in content that will add semantic marking. This is future (for now).

Could I set a Cruise as an Event in Schema mark up?
Hi there, We are now in the process of implementing a JSON-LD mark-up solution and are building cruises as an event. Will this work and can we get away with this without penalty? Previously they have been marking their cruises as events using the data highlighter and this has displayed correctly in the SERP. The ideal schema would be Trip but this is not supported by Google Rich Results yet, hopefully they will support this in the future. Another alternative would be product but this does not display rich-results as we would like. Event has the best result in terms of how the information is displayed. For example someone might search "Cruises to Spain" and the landing page would display the next 3 cruises that go to Spain, with dates & prices. The event location would be the cruise terminal, the offer would be the starting price and the start & end date would be the cruise duration, these are fixed dates. I am interested to hear the communities opinion and experience with this problem.

How To Optimize For Same Word, Different Spelling
Hi all. Just wondering what peoples stance is on using multiple variations of keywords on a webpage - those keywords that have the same meaning and search intent, but are just spelt differently. i.e. 'woodscrews' and 'wood screws' (the latter has a significantly higher search volume) You could approach the webpage in 4 different ways; 1. Use ONLY 'wood screws' on-page, and in the page <title><br />2. Use ONLY 'woodscrews' on-page, and in the page <title><br />3. Use BOTH 'wood screws' and 'woodscrews' on-page, and BOTH in the page <title><br />4. Use BOTH 'wood screws' and 'woodscrews' on-page, but ONLY one variation in the page <title></p> <p>We've run some tests in the past but there were never any clear takeaways, a mixed bag of results really.</p> <p>Also, If they are considered the same keyword by Google why are the ranking positions always different for each variation?</p> <p>I'm not sure there' a specific answer to this, just interested to hear peoples thoughts really.</p> <p>Many thanks in advance!</p> <p>Lee.</p></title>

Hreflang : mixing with/without country code for same language
Hello, I would like to display 3 different english versions of my website : 1 for UK, 1 for CA and 1 for other english users. It would look like this for a page: . (english content with £ prices) <link rel="alternate" href="https: xxx.com="" en-ca" hreflang="en-CA">(english content with $CA prices)</link rel="alternate" href="https:> <link rel="alternate" href="https: xxx.com="" en="" " hreflang="en">(english content without currency)</link rel="alternate" href="https:> I wonder if I can mix this hreflang without country code with hreflangs with country code for the 2 other specific versions... or if the hreflang without country code version will appear whatever the country, even if i specified it . In other terms, is hreflang="en" > hreflang="en-CA" + hreflang="en-GB" if tagged together on a same page? Thank you

Do I need to add the actual language for meta tags and description for different languages? cited for duplicate content for different language
Hi, I am fairly new to SEO and this community so pardon my questions. We recently launched on our drupal site mandarin language version for the entire site. And when i do the crawl site, i get duplicate content for the pages that are in mandarin. Is this a problem or can i ignore this? Should i make different page titles for the different languages? Also, for the metatag and descriptions, would it better in the native language for google to search for? thanks in advance.

Benefits of Rich Snippets for financial products
Does anyone have experience of using rich snippets for non-physical products? Our website offers credit cards comparison service. Do you think that tagging each card's page with rich snippets such as credit card image, name, description and category makes sense? The idea is to make it stand out in the search results.
