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).

Event Schema for Multiple Occurrences
I am wondering the best way to mark up an event page with multiple occurrences. For example, we have an event that happens over the course of 4 sequential weekends:
Intermediate & Advanced SEO | | Your_Workshop
9/28-9/29
10/5-10/6
10/12-10/13
10/19-10/20 Our website allows us to enter multiple occurrences that results in a single event listing page which outputs all dates (to eliminate duplicate content, titles, metas, etc.) but allows each occurrence to output individually on our events calendar in the respective individual date. Each time the event is shown, it links to the same listing page. I am wondering if we can add event schema on a single listing multiple times to cover each occurrence. In the above example, we would have 4 schemas on the listing page for each date range/weekend. In our current schema, we end up with a start and end date identified as 9/28-10/20 but it is not clear that the event is just happening on the weekends with gaps in between. Any suggestions are welcome however, we are really trying to NOT list each as an individual event on the website both for the duplicate content issue and the extra burden on our client that lists events for a very large geographic area.0 -
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>

Difference LSI and and secondary related keywords
Hi, It is confusing to me. So far what I understand is the following: LSI are synonyms of the keyword your target (the one in the H1 and title tag). For example my keyword would be "Tuscany bike tour" and my LSI would be "Tuscany cycling vacation", "bicycle tour in Tuscany" etc... Then secondary related keyword are for me the other topics I need to cover in my content. In this case for example it would be "Florence", "Siena". But from what I understand a good writer wouldn't use "Siena" or "Florence" multiple times in it's content it would replace it by keywords that support them such as "the town of Florence", "the city of Siena"," the Palio of Siena" etc...Is my understanding correct ? If so what is the use of using those secondary related keyword, is it to rank on other keywords such as Palio of siena tuscany bike tour ? or just not to repeat a secondary keyword too many times. If i write the Palio of Siena isn't it considered as another topic that the topic siena ? Thank you,

Google News Sitemap in Different Languages
Thought I'd ask this question to confirm what I already think. I'm curious that if we're publishing something in two language and both are verified by the publishing center if the group would recommend publishing two separate Google News Sitemaps (one in each language) or publishing one in each language.

Two Different Domains exact same content
Hello, I suspect I know the answer to this but would like to have it confirmed. I have been speaking to a company the last couple of weeks who have 2 domains with the exact same content. Possible a third but they haven't supplied a link. This from all I've read would be a huge problem for ranking and SEO. What would be the best way to deal with this ? I did do a search and found articles/questions on same content on the same site and in articles etc but nothing about exactly the same websites on 2 domains. Cheers David.
