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).

Multiple Markups on The Same Page - Best Solution?
Hi there! I have a website that is build in react javascript, and I'm trying to use markup on my pages. They are mostly articles about general topics with common questions (about the topic), and for most articles I would like to use two markups: article markup + FAQ Markup ( for the questions in the article) article markup + how-to markup Can I do this or will Google get confused? Since I have two @type at the same time, for example @type": "FAQPage" and "@type": "Article". How should I think? I'm using https://schema.dev/ right now. Thanks!

Is there a benefit to changing .com domain to .edu?
Hey All! I'm wondering if there is any benefit (or if benefit could possibly outweigh the cost) to changing a domain from .com to a new .edu domain. The current .com domain has decent credibility already, and the .edu will have never been used before.

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,

Multiple pages optimised for the same keywords but pages are functionally different and visually different
Hi MOZ community! We're wondering what the implications would be on organic ranking by having 2 pages, which have quite different functionality were optimised for the same keywords. So, for example, one of the pages in question is
Intermediate & Advanced SEO | Aug 30, 2018, 9:39 AM | TrueluxGroup
https://www.whichledlight.com/categories/led-spotlights
and the other page is
https://www.whichledlight.com/t/led-spotlights both of these pages are basically geared towards the keyword led spotlights the first link essentially shows the options for led spotlights, the different kind of fittings available, and the second link is a product search / results page for all products that are spotlights. We're wondering what the implications of this could be, as we are currently looking to improve the ranking for the site particularly for this keyword. Is this even safe to do? Especially since we're at the bottom of the hill of climbing the ranking ladder of this keyword. Give us a shout if you want any more detail on this to answer more easily 🙂0 -

Is there any benefit to this? Should I remove it and just have them end with a forward slash?
If I 301 redirect the old .html URLs to the forward slash URLs, will I lose PA? Thanks!0
