Need a layman's definition/analogy of the difference between schema and structured data
-
I'm currently writing a blog post about schema. However I want to set the record straight that schema is not exactly the same as structured data, although both are often used interchangeably. I understand this schema.org is a vocabulary of global identifiers for properties and things. Structured data is what Google officially stated as "a standard way to annotate your content so machines can understand it..."
Does anybody know of a good analogy to compare the two?
Thanks!

Hi Rosemary, Dave here.
I like to think of it like our addressing system. Because we all use the same system and format for our addresses on an envelope we don't need a code to tell us but as you know ... everyone displays their product information and other data differently on a page. Because of that the engines can have difficulty telling what bit of data is what. Is "blue" the color of the product, the color of the screen or simply used on the page in a "Don't feel blue ... buy XYZ !"
Structured data, as Matt well-noted, is just an idea really of matching information with what it means. Like saying "blue" = "product color".
Of course, that's all well-and-good but we can all build our own systems and many have been. If we're all using different systems then nothing makes sense so folks got together and created Schema.org simply as a body that could help create a standard. Like saying, "on an envelop you put the name first, then the address, then the city, then the state, then the zip code". If we put things on the envelop differently things would get messy so Schema basically gives us the instruction on how to pass information across. Schema isn't the idea or even the data, it's the instructions on how to tell Google what specific data means.
Clear as mud?

Well, let's see.
Structured data in this sense comes down to a method of labelling elements of your site in order to clarify what they are for search engine crawlers, microdata is a form of structured data that works in HTML5, and Schema is a standard for microdata. So Schema is microdata is structured data. All Schema (in this use) is structured data, but not all structured data is Schema.
Maybe something like, if structured data represents all the team sports in the world, and microdata represents every game intended to be played on a football pitch, then Schema may be the Laws of the Game—the standard rules for international soccer.
Also, go Seattle Sounders!

Yes, thank you. However I'm looking for a simple layman's analogy. Most of the blog post readers are not going to be able to comprehend the technical aspects.

Hi Rosemary! There's actually a pretty decent explanation here: https://moz.com/learn/seo/schema-structured-data
Structured data is a system of pairing a name with a value that helps search engines categorize and index your content. Microdata is one form of structured data that works with HTML5. Schema.org is a project that provides a particular set of agreed-upon definitions for microdata tags.
Does that make sense?

After hack and remediation, thousands of URL's still appearing as 'Valid' in google search console. How to remedy?
I'm working on a site that was hacked in March 2019 and in the process, nearly 900,000 spam links were generated and indexed. After remediation of the hack in April 2019, the spammy URLs began dropping out of the index until last week, when Search Console showed around 8,000 as "Indexed, not submitted in sitemap" but listed as "Valid" in the coverage report and many of them are still hack-related URLs that are listed as being indexed in March 2019, despite the fact that clicking on them leads to a 404. As of this Saturday, the number jumped up to 18,000, but I have no way of finding out using the search console reports why the jump happened or what are the new URLs that were added, the only sort mechanism is last crawled and they don't show up there. How long can I expect it to take for these remaining urls to also be removed from the index? Is there any way to expedite the process? I've submitted a 'new' sitemap several times, which (so far) has not helped. Is there any way to see inside the new GSC view why/how the number of valid URLs in the indexed doubled over one weekend?

Can an "Event" in Structured Data For Google Be A Webinar?
I have a client who is has structured data for live business webinars. Google's documentation seems to talk more about music and tickets than this kind of thing. At the same time, we get an error in search console for "Name" and location, which they list as "webinar." Should I removed this failed structured data attempt or is there a way to fix it? Thanks!

Magento: Should we disable old URL's or delete the page altogether
Our developer tells us that we have a lot of 404 pages that are being included in our sitemap and the reason for this is because we have put 301 redirects on the old pages to new pages. We're using Magento and our current process is to simply disable, which then makes it a a 404. We then redirect this page using a 301 redirect to a new relevant page. The reason for redirecting these pages is because the old pages are still being indexed in Google. I understand 404 pages will eventually drop out of Google's index, but was wondering if we were somehow preventing them dropping out of the index by redirecting the URL's, causing the 404 pages to be added to the sitemap. My questions are: 1. Could we simply delete the entire unwanted page, so that it returns a 404 and drops out of Google's index altogether? 2. Because the 404 pages are in the sitemap, does this mean they will continue to be indexed by Google?

Should HTML be included in the structured data (schema) markup for the main body content?
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!

404's - Do they impact search ranking/how do we get rid of them?
Hi, We recently ran the Moz website crawl report and saw a number of 404 pages from our site come back. These were returned as "high priority" issues to fix. My question is, how do 404's impact search ranking? From what Google support tells me, 404's are "normal" and not a big deal to fix, but if they are "high priority" shouldn't we be doing something to remove them? Also, if I do want to remove the pages, how would I go about doing so? Is it enough to go into Webmaster tools and list it as a link no to crawl anymore or do we need to do work from the website development side as well? Here are a couple of examples that came back..these are articles that were previously posted but we decided to close out: http://loyalty360.org/loyalty-management/september-2011/let-me-guessyour-loyalty-program-isnt-working http://loyalty360.org/resources/article/mark-johnson-speaks-at-motivation-show Thanks!

301 v/s 302 Redirection on Homepage (Multilingual)
Hello, Our website: http://www.luxresorts.com currently has a default 302 redirection to http://www.luxresorts.com/en. We would like to do a 301 redirection instead of a 302 to http://www.luxresorts.com. Our concern is that the site is multilingual and we wonder what effect would the 301 redirection have on search engine crawlers and how would this appear on SERP. When a search is done on Google.com, the English version of our website appears and when on Google.FR, the French version appears. Would the 301 redirection change the way our website appear on Google? Grateful if you could help us out in understanding the pros and cons/best practices for our concern. Thanks in advance. Tej Luchmun.

Do links to PDF's on my site pass "link juice"?
Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use. The great SEO side of this is that they link to my site. The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files. So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site. So do I get any benefit from these great links? If not, does anybody have any suggestions on how I could get credit for them. Keep in mind that editing the PDF's are not allowed by the government. Thanks.

Soft 404's from pages blocked by robots.txt -- cause for concern?
We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages). Should we be concerned? Is there anything we can do about this?
