Duplicate Schema Syntax
-
Is having both JSON and Microdata markup on one site detrimental to SEO? I'm unsure if Google would read it as spammy to have both.

Thanks, Paddy!

Thank you for digging that up, Alex!

Hi Christine,
As Alex said, this shouldn't be a problem. I'd just advise keeping things consistent where you can, if only from a maintenance/debugging perspective so that if something breaks, it's easier to diagnose.
You should also make sure that markup is consistent between mobile and desktop sites if you have separate sites or change content based on each one.
Cheers.
Paddy

Google's Gary Illyes has specifically stated that it wouldn't be a problem when someone else asked the same question:
"Is there an issue (ie. spammy structured markup manual action) with marking up the same content using both JSON-LD & microdata?"

"no, that shouldn't be a problem"

Unsolved Duplicate LocalBusiness Schema Markup
Hello! I've been having a hard time finding an answer to this specific question so I figured I'd drop it here. I always add custom LocalBusiness markup to clients' homepages, but sometimes the client's website provider will include their own automated LocalBusiness markup. The codes I create often include more information. Assuming the website provider is unwilling to remove their markup, is it a bad idea to include my code as well? It seems like it could potentially be read as spammy by Google. Do the pros of having more detailed markup outweigh that potential negative impact?

Does having 2 separate domains with similar content always = duplicate content?
I work for a global company which is in the process of launching their US & European websites, (just re-launched Australian site, migrated from an old domain) all with separate domains with the purpose of localising. However, the US website content will essentially be the same as the Australian one with minor changes (z instead of s, slightly different service offerings etc) but the core information will be the same as the AU site. Will this be seen as duplicate content and Is there a way we can structure this so that the content won’t be seen as duplicate but is still a separate localised website? Thank you.

Will hreflang eliminate duplicate content issues for a corporate marketing site on 2 different domains?
Basically, I have 2 company websites running. The first resides on a .com and the second resides on a .co.uk domain. The content is simply localized for the UK audience, not necessarily 100% original for the UK. The main website is the .com website but we expanded into the UK, IE and AU markets. However, the .co.uk domain is targeting UK, IE and AU. I am using the hreflang tag for the pages. Will this prevent duplicate content issues? Or should I use 100% new content for the .co.uk website?

On what pages of my site should I put schema.org structured markup for an Aggregate Review of a Concrete Construction Contractors work?
I have a concrete contractor that I do a site for. He has many reviews from Home Advisor. So I created a Structured Data Markup using HTML5\. I put the the AggregateReview near the bottom of the About Us page at [http://www.skv-construction.com/about-us.html](http://www.skv-construction.com/about-us.html). Question 1: Should I also put the AggregateReview on the home page, or on specific project pages. Question 2: How will Google use the data now if the About page is NOT searched or displayed in SERPs. Does Google display this markup when and where they want to? Question 3: Siince this is a Local Business, should I embed the AggregateReview within the LocalSearch tag. I passed the Google test as it is for the Aggregate Review! But I have the review wrapped in the HomeAndConstructionBusiness tag. Here is the code: "http://schema.org/HomeAndConstructionBusiness"> # Quality Workmanship w 50 Yrs Experience "http://schema.org/AggregateRating"> 4.37 stars-based on 54 reviews at ["http://www.homeadvisor.com/rated.SKVConstruction.18028291.html"](<a) target="_blank">Home Advisor "http://schema.org/PostalAddress"> 10005 Fair Lane <spam itemprop="addresslocality" union=""></spam> IL 60180 (847) 364 0161 ["http://www.skv-construction.com/contact-us.html"](<a)>Contact Us Price Range: All Jobs Custom; Call for Quote or Visit Web Site Would appreciate any help. This markup is so vague, I can see why few people are using it. Maybe you should do a Video training or extended training on how to's. Vernon Wanner 815-332-8062

Implementation advice on fighting international duplicate content
Hi All, Let me start by explaining that I am aware of the rel="canonical" and **rel="alternate" hreflang="x" **tags but I need advice on implementation. The situation is that we have 5 sites with similar content. Out of these 5: 2 use the same URL stucture and have no suffix 2 have a different URL structure with a .html suffix 1 has an entirely different URL structure with a .asp suffix The sites are quite big so it will take a lot of work to go through and add rel="alternate" hreflang="x" tags to every single page (as we know the tag should be applied on a page level not site level). 4 out of the 5 sites are managed by us and have the tag implemented so that makes it easier but the 5th is managed in Asia and we fear the amount of manual work required will put them off implementing it. The site is due to launch at the end of the month and we need to sort this issue out before it goes live so that we are not penalised for duplicate content. Is there an easy way to go about this or is the only way a manual addition? Has anyone had a similar experience? Your advice will be greatly appreciated. Many thanks, Emeka.

Does Schema Replace Conventional NAP in local SEO?
Hello Everyone, My question is in regards to Schema and whether the it replaces the need for the conventional structured data NAP configuration. Because you have the ability to specifically call out variables (such as Name, URL, Address, Phone number ect.) is it still necessary to keep the NAP form-factor that has historically been required for local SEO? Logically it makes sense that schema would allow someone to reverse this order and still achieve the same result, however I have yet to find any conclusive evidence of this being the case. Thanks, and I look forward to what the community has to say on this matter.

Local site went from dominating first page - bad plugin caused duplicate content issues - now to 2nd page for all!
I had a bad plugin create duplicate content issues on my Wordpress CMS - www.pmaaustin.com I got it fixed, but now every keyword has been stuck on page 2 for search terms for 4 months now, where I was 49 out of 52 keywords on page one. It's a small local niche with mostly easier to rank keywords. Am I missing something? p.s. Also has a notice on the Dashboard that says: "404 Redirected: There are 889 captured 404 URLs that need to be processed." Could that be a problem? Thanks, Steve
