      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).

              If you wish to read more about creation of JSON-LD then this article is for you:

                Schema Markup Validator vs. Rich Results Test

                schema structured data

                I am working on a schema markup project. When I test the schema code in the Schema Markup Validator, everything looks fine, no errors detected. However, when I test it in the Rich Results Test, a few errors come back.
                What is the difference between these two tests? Should I trust one over the other?

                For FAQ Schema markup, do we need to include every FAQ that is on the page in the markup, or can we use only selected FAQs?

                The website FAQ page we are working on has more than 50 FAQs. FAQ Schema guidelines say the markup must be an exact match with the content. Does that mean all 50+ FAQs must be in the mark-up? Or does that mean the few FAQs we decided to put in the markup are an exact match?

                :Pointing hreflang to a different domain

                Hi all, Let's say I have two websites: www.mywebsite.com and www.mywebsite.de - they share a lot of content but the main categories and URLs are almost always different. Am I right in saying I can't just set the hreflang tag on every page of www.mywebsite.com to read: rel='alternate' hreflang='de' href='http://mywebsite.de' /> That just won't do anything, right? Am I also right in saying that the only way to use hreflang properly across two domains is to have a customer hreflang tag on every page that has identical content translated into German? So for this page: www.mywebsite.com/page.html my hreflang tag for the german users would be: <link < span="">rel='alternate' hreflang='de' href='http://mywebsite.de/page.html' /></link <> Thanks for your time.

                Should brand/company be included in meta title?

                Is there any point/benefit/requirement in using brand/company name in the meta title, I realise search engines like Google prefer brand focused pages, However it is unlikely that someone would be including the company in our search terms. Any thoughts?

                The benefits from having a dedicated IP

                Is the true? Claim by SiteGround Having a dedicated IP for each website is considered by some experts as an advantage for search engine optimization. There is a common believe that sites with dedicated IP addresses do better in the search engine results than those on shared IPs. Such sites do not share the risk of being banned for sharing the same IP in case another website hosted on the same server gets banned by a search engine.

                Citation/Business Directory Question...

                A company I work for has two numbers... one for the std call centre and one for tracking SEO. Now, if local citation/business directory listings have the same address but different numbers, will this affect local/other SEO results? Any help is greatly appreciated! 🙂

                Schema.org on Youtube iframe embed?

                So I've tried scouring the internet on the proper way to markup youtube videos. I know there's the VideoObject propery but that seems to be more made for the old school embed code that looks like this: <embed width="100%" id="video-player-flash" height="100%" type="application/x-shockwave-flash" src="http://s.ytimg.com/yt/swfbin/watch_as3-vflpp9opi.swf" allowscriptaccess="always" allowfullscreen="true" bgcolor="#000000" flashvars="el=embedded&fexp=904001%2C914057%2C918000%2C910206%2C907217%2C907335%2C921602%2C919306%2C922600%2C919316%2C920704%2C912804%2C913542%2C919324%2C912706&is_html5_mobile_device=false&tabsb=1&hl=en_US&eurl=http%3A%2F%2Fwww.dial800.com%2Fblog%2Fvideos%2Fdial800-product-overview-video&iurl=http%3A%2F%2Fi4.ytimg.com%2Fvi%2Fgk1aD9UCKYA%2Fhqdefault.jpg&tspto=12000&probably_logged_in=1&tsp_buffer=10&video_id=gk1aD9UCKYA&tsp_dvrloop=50&sendtmp=1&enablejsapi=1&sk=WZy3rFIXzzhTB_BpmE1p1tTsbxMib1vIC&rel=1&playlist_module=http%3A%2F%2Fs.ytimg.com%2Fyt%2Fswfbin%2Fplaylist_module-vfl3lol2H.swf&jsapicallback=ytPlayerOnYouTubePlayerReady&playerapiid=player1&framer=http%3A%2F%2Fwww.dial800.com%2Fblog%2Fvideos%2Fdial800-product-overview-video"> Do I need to use that code or is it possible to mark it up using just the clean iframe src that youtube provides now?
