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?

Looking for opinions on structuring meta title tags/page title/menu title/H1
Hi everyone I am hoping a few of you can share your opinions. I have been having conversations (okay, healthy debates) about how to write/structure meta title tag and how to compliment them with the H1, page title, menu name. To help explain the thought processes I will use a pretend keyword. How about "screwdriver". Case: (I made this up) we are redesigning a website for a construction tools manufacturing company (pretend name: ABC Tools) targeting OEMs who are interested in purchasing large quantities of tools. The product categories (to become main menu items) are Screwdrivers, Nails, Drills, and Hammers. (bear with me .... this is just an example I am making up on the fly) K. Circling back to screwdrivers - let's say we have one landing page (a primary category page and in the main menu) listing products and great details about screwdrivers. Focus keywords are screwdriver manufacturer, screwdriver supplier, construction screwdrivers Below are questions being debated. If you are willing ... how would you address these questions? And, can you explain WHY? QUESTION ONE: How would you structure the meta title tag (feel free to write one of your own) Screwdriver Manufacturer - Construction Screwdriver | ABC Tools ABC Tools - US-based Screwdriver Manufacturer Supplier Near You High-Quality Screwdrivers for Construction with ABC Tools QUESTION TWO: how would you write the H1 on the page? Would it match the meta tag? OR, would you write something different using the primary keyword? QUESTION THREE Remembering this is not a blog post ... it is a primary landing page linked to the main navigation. What would the menu title be? (remember the product categories above are how the main menu items are bucketed) Screwdrivers Screwdriver Manufacturer Typically in WordPress, the H1 and the menu title is auto-populated using the page title (not the title tag)... So, if we use Screwdrivers as the page title but we want the H1 to match the meta title tag, would we manually change the H1? Or, have the page title and title tag match, but manually change the menu item?

How will changing my website's page content affect SEO?
Our company is looking to update the content on our existing web pages and I am curious what the best way to roll out these changes are in order to maintain good SEO rankings for certain pages. The infrastructure of the site will not be modified except for maybe adding a couple new pages, but existing domains will stay the same. If the domains are staying the same does it really matter if I just updated 1 page every week or so, versus updating them all at once? Just looking for some insight into how freshening up the content on the back end pages could potentially hurt SEO rankings initially. 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.

Does Google Read URL's if they include a # tag? Re: SEO Value of Clean Url's
An ECWID rep stated in regards to an inquiry about how the ECWID url's are not customizable, that "an important thing is that it doesn't matter what these URLs look like, because search engines don't read anything after that # in URLs. " Example http://www.runningboards4less.com/general-motors#!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 Basically all of this: #!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 That is a snippet out of a conversation where ECWID said that dirty urls don't matter beyond a hashtag... Is that true? I haven't found any rule that Google or other search engines (Google is really the most important) don't index, read, or place value on the part of the url after a # tag.

Brackets vs Encoded URLs: The "Same" in Google's eyes, or dup content?
Hello, This is the first time I've asked a question here, but I would really appreciate the advice of the community - thank you, thank you! Scenario: Internal linking is pointing to two different versions of a URL, one with brackets [] and the other version with the brackets encoded as %5B%5D Version 1: http://www.site.com/test?hello**[]=all&howdy[]=all&ciao[]=all
Intermediate & Advanced SEO | | mirabile
Version 2: http://www.site.com/test?hello%5B%5D**=all&howdy**%5B%5D**=all&ciao**%5B%5D**=all Question: Will search engines view these as duplicate content? Technically there is a difference in characters, but it's only because one version encodes the brackets, and the other does not (See: http://www.w3schools.com/tags/ref_urlencode.asp) We are asking the developer to encode ALL URLs because this seems cleaner but they are telling us that Google will see zero difference. We aren't sure if this is true, since engines can get so _hung up on even one single difference in character. _ We don't want to unnecessarily fracture the internal link structure of the site, so again - any feedback is welcome, thank you. 🙂0 -
What's the best way to redirect categories & paginated pages on a blog?
I'm currently re-doing my blog and have a few categories that I'm getting rid of for housecleaning purposes and crawl efficiency. Each of these categories has many pages (some have hundreds). The new blog will also not have new relevant categories to redirect them to (1 or 2 may work). So what is the best place to properly redirect these pages to? And how do I handle the paginated URLs? The only logical place I can think of would be to redirect them to the homepage of the blog, but since there are so many pages, I don't know if that's the best idea. Does anybody have any thoughts?

Include Cross Domain Canonical URL's in Sitemap - Yes or No?
I have several sites that have cross domain canonical tags setup on similar pages. I am unsure if these pages that are canonicalized to a different domain should be included in the sitemap. My first thought is no, because I should only include pages in the sitemap that I want indexed. On the other hand, if I include ALL pages on my site in the sitemap, once Google gets to a page that has a cross domain canonical tag, I'm assuming it will just note that and determine if the canonicalized page is the better version. I have yet to see any errors in GWT about this. I have seen errors where I included a 301 redirect in my sitemap file. I suspect its ok, but to me, it seems that Google would rather not find these URL's in a sitemap, have to crawl them time and time again to determine if they are the best page, even though I'm indicating that this page has a similar page that I'd rather have indexed.

Is there any negative SEO effect of having comma's in URL's?
Hello, I have a client who has a large ecommerce website. Some category names have been created with comma's in - which has meant that their software has automatically generated URL's with comma's in for every page that comes beneath the category in the site hierarchy. eg. 1 : http://shop.deliaonline.com/store/music,-dvd-and-games/dvds-and-blu_rays/ eg. 2 : http://shop.deliaonline.com/store/music,-dvd-and-games/dvds-and-blu_rays/action-and-adventure/ etc... I know that URL's with comma's in look a bit ugly! But is there 'any' SEO reason why URL's with comma's in are any less effective? Kind Regs, RB
