Hi lovely community, I know google made some schema changes in Sept 2019. I got an AggregateRating Error:
One of offers or review or aggregateRating should be provided. I am using a third-party app 'Shopify Product Review' to implement the rating. What I should do to solve this error. Thanks very much for the help! I found many people have this issue too in the community! Many thanks Pui

Greetings: It was pointed out to me that the h1 tags on my website (www.nyc-officespace-leader.com) all had exactly the same text and that duplication may be contributing to the very low page authority for most URLs. The duplicate h1 appears in line 54-54 (see below) of the home page: www.nyc-officespace-leader.com: itemscope itemtype="http://schema.org/LocalBusiness" style="position:absolute;top:-9999em;"> <span<br>itemprop="name">Metro Manhattan Office Space</span<br> <img< p="">But the above refers to schema" so is this really duplicate H1 or is there an exception if the H1 is within a schema? Also, I was told that the company street address and city and state were set up incorrectly as part of an alt tag. However these items also appear as schema in lines 49-68 shown below: Dangerous for me to perform surgery on the code without being certain about these key items!! Could ask my developer, however they may be uncomfortable considering that they set this up in the 1st place. So the view of neutral professionals would be highly welcome! itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
<span<br>itemprop="streetAddress">347 5th Ave #1008
<span<br>itemprop="addressLocality">New York
<span<br>itemprop="addressRegion">NY
<span<br>itemprop="postalCode">10016<div<br>itemprop="brand" itemscope itemtype="http://schema.org/Organization">

We are adding json+ld data to an ecommerce site and myself and one of the other people working on the site are having a minor disagreement on things. What it comes down to is how to mark up the category page. One of us says it needs to be marked up with as an Itempage, https://schema.org/ItemPage  The other says it needs to be marked up as products, with multiple product instances in the schema, https://schema.org/Product The main sticking point on the Itemlist is that Itemlist is a child of intangible, so there is a feeling that should be used for things like track listings or other arbitrary data.

Can we have organization markup schema for subdomain ? For example if my main domain is xyz.com and subdomain is sub.xyz.com If i plan to have organization markup schema for subdomain how should it look like ? Should the markup schema must have main domain url or sub domain url in markup schema ? Should it be like this ?

Lately we have been applying structured data to the main content body of our client's websites.  Our lead developer had a good question about HTML however. In JSON-LD, what is the proper way to embed content from a data field that has html markup (i.e. p, ul, li, br, tags) into mainContentOfPage. Should the HTML be stripped our or escaped somehow? I know that apply schema to the main body content is helpful for the Googlebot.  However should we keep the HTML?  Any recommendations or best practices would be appreciated. Thanks!

Hi everyone - What is the best way to deal with 404s on an old site when you're migrating to a new website? Thanks, Luke

when plugging ALT tags into images, does Google prefer spaces, hyphens, or underscores?  I know with filenames, hyphens or underscores are preferred and spaces are replaced with %20. Thoughts? Thanks!
