When to Use Schema vs. Facebook Open Graph?
-
I have a client who for regulatory reasons cannot engage in any social media: no Twitter, Facebook, or Google+ accounts. No social sharing buttons allowed on the site. The industry is medical devices.
We are in the process of redesigning their site, and would like to include structured markup wherever possible. For example, there are lots of schema types under MedicalEntity: http://schema.org/MedicalEntity
Given their lack of social media (and no plans to ever use it), does it make sense to incorporate OG tags at all? Or should we stick exclusively to the schemas documented on schema.org?
-
Serendipitous timing - this article was posted yesterday about using mark-up, and how Open Graph and Schema.org are used, and why to use both:
Facebook Open Graph serves its purpose well, but it doesn’t provide the detailed information search engines need to improve the user experience. A single web page may have many components, and it may talk about more than one thing. Even if you mark up your content for Facebook Open Graph, schema.org provides an additional way to provide more detail about particular entities on the page.

I personally would use both. They way that I look at it with the OG tags is that you are controlling the consistency of the brand across platforms that you do not officially support. This is very much in my mind the same thing as making a page display correctly in older version of IE.
-
OG and Schema can live in the wild together. They are both ways to show information around the entities which they describe.
IMDB is using both OG and Schema to mark up their data:

Thanks, Craig. Do you know if any of the OG and schema tags would duplicate or conflict? I see a lot of documentation about using one or the other, but not how to use both harmoniously.
-
Thanks Keri, interesting example. While the GE Healthcare site is more commercial in intent, I like how they've treated the share functionality using the node icon. Subtle, yet shareable

-
I haven't checked in depth, the regulations are with the FDA and they aren't the most up-to-date with social media practices! No competitors are using OG yet, but their sites are also very under-optimized.
-
This may be way over-the-top, but have you checked if OG tags would violate the regulations at all, or if they could potentially be a violation down the road? Granted, even though I haven't read the regulations, I don't think it should...but it's just something I'd double-check. I could see a potential problem if the wording is ambiguous and a competitor wants to stir up trouble for you.
-
Given that other people may share those pages, I would incorporate both OG and Schema on the site.
-
Just because you can't share doesn't mean people aren't going to share it on FB. Just yesterday, I shared http://www3.gehealthcare.com/en/Products/Categories/Accessories_and_Supplies/Adventure_Series_for_CT/Pirate_Island on FB with my friends. I don't have formal experience in this area, but did want to point that out. There was an article on slate.com about the design of these, and I went looking for more information, and found that page.

How safe is it to use a meta-refresh to hide the referrer?
Hi guys, So I have a review site and I'm affiliated with several partnership programs whose products I advertise on my site. I don't want these affiliate programs to see the source of my traffic (my site), so I'm looking for a safe solution to hide the referrer URL. I have recently added a rel="noreferrer" tag to all my affiliate links, but this method isn't perfect as not all browsers respect that rule. After doing some research and checking my competitors I noticed that some of them use meta-refresh, which seems more reliable in this regard. So, how safe is it to use meta-refresh as means of hiding referrer URL? I'm worrying that implementing a meta-refresh redirect might negatively affect my SEO. Does anybody have any suggestions on how to hide the referrer URL without damaging SEO? Thank you.

Hreflang in vs. sitemap?
Hi all, I decided to identify alternate language pages of my site via sitemap to save our development team some time. I also like the idea of having leaner markup. However, my site has many alternate language and country page variations, so after creating a sitemap that includes mostly tier 1 and tier 2 level URLs, i now have a sitemap file that's 17mb. I did a couple google searches to see is sitemap file size can ever be an issue and found a discussion or two that suggested keeping the size small and a really old article that recommended keeping it < 10mb. Does the sitemap file size matter? GWT has verified the sitemap and appears to be indexing the URLs fine. Are there any particular benefits to specifying alternate versions of a URL in vs. sitemap? Thanks, -Eugene

Using pictures from another domain
We are building several sites for several clients which will be using images from the manufacturer. Our dev team wants to insert the manufacturer's url for the images, instead of actually downloading the image and hosting on our server. There are thousands of images, so downloading images to our server will be time consuming, so we are looking for a shortcut.... however I'm concerned this will cause other issues. Is using manufactueresdomain.com/12345.jpg going to cause SEO issues? will this generate Google penalties? Since we are not able to control the image file name, we cannot optimize it. We will add Alt text and Title tag for each image, but the file name is random characters. How important is the file name for SEO?

Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)
Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
Intermediate & Advanced SEO | | browndoginteractive
2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality: http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results: Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index: robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages. I say "force" because of the crawl budget required. Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links. Best of both worlds: crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution: using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.0 -

Should I use rel=canonical on similar product pages.
I'm thinking of using rel=canonical for similar products on my site. Say I'm selling pens and they are al very similar. I.e. a big pen in blue, a pack of 5 blue bic pens, a pack of 10, 50, 100 etc. should I rel=canonical them all to the best seller as its almost impossible to make the pages unique. (I realise the best I realise these should be attributes and not products but I'm sure you get my point) It seems sensible to have one master canonical page for bic pens on a site that has a great description video content and good images plus linked articles etc rather than loads of duplicate looking pages. love to hear thoughts from the Moz community.

Using the Word "Free" in Metadata
Hi Forum! I've searched previous questions, and couldn't find anything related to this. I know the word "free" when used in email marketing can trigger spam filters. If I use the word "free" in my metadata (title tag, description, and keywords just for fun) will I be penalized in any way? Thanks!

Meta Keywords: Should we use them or not?
I am working through our site and see that meta keywords are being used heavily and unnecessarily. Each of our info pages will have 2 or 3 keyword phrases built into them. Should we just duplicate the keyword phrases into the meta keyword field, should put in additional keywords beyond or not use it at all? Thoughts and opinions appreciated
