Does Bing support rel="canonical" HTTP Headers?
-
anyone know^
-
Yeah, I'm honestly not 100% sure on the HTTP header version, but I'd bet they don't support it. It won't hurt to try it, though, and you'd at least cover Google - I think it's probably a good best practice for PDFs that have HTML equivalents.

Hey Peter,
I am attempting to add the HTTP Header for PDF Files. I really feel that this can be a bonus for sites that do have duplicated PDF content, especially on large e-commerce based sites.
I figured that they(Bing) didnt support it, and it sounds like it is probably not considered in the form of an HTTP Header
I may have to consider conditional logic and/or create a dynamic robots.txt file to disallow these PDF files for all other search engines, while serving up canonical HTTP Headers for Google, assuming that Bing doesnt support it.
It would be good to try and test, I may just end up doing that

I don't believe that Bing supports the HTTP header version of rel="canonical". They do technically support the link attribute (their comment about it being a "hint" was from 2009) - Duane confirmed that last year (I asked him point blank). Although, honestly, experiences vary and many SEOs claim that their support is inconsistent even for the link attribute.
Honestly, when it comes to canonicalization, when in doubt, try it. The worst that can happen in most scenarios (implemented properly) is that it just doesn't work.
Out of curiosity, why are your trying to use the HTTP Header version. Is it a non-HTML file (like a PDF)?

Hi Brandon
"No "Bing does not support rel="canonical" HTTP Headers, Bing isn’t supporting the canonical link element. Bing says canonical tags are hints and not directives, So 301 redirects are your best friend for redirecting, use rel=”nofollow” on useless pages, and use robots.txt to keep content you don’t want crawled out. When you have duplicate problems due to extra URLs parameters, use the URL Normalization feature.

I think you guys are confused. There is a difference between the rel="canonical" HTTP header, and a rel="canonical" tag.
I understand their stance with regards to the tag, but wonder if they even consider the canonical in the form of an HTTP Header.

Does Bing support rel="canonical" HTTP Headers?
** No.
Bing posted: "This tag will be interpreted as a hint by Live Search, not as a command. We'll evaluate this in the context of all the other information we know about the website and try and make the best determination<a> of the canonical URL</a>. This will help us handle any potential implementation errors or abuse of this tag."

Well Brandon, Bing has officially said that they see it as only a hint and determine in their senses as to what is right, but SEO folks do use the tag and I don't think anyone has yet had a problem. You can have a glimpse at the latest SEOmoz talk on this too.
Cheers,

Rel canonical tag from shopify page to wordpress site page
We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

Why has my website been removed from Bing?
I have a website that has recently been removed from Bing's index, but can't figure out why. The website isn't new, and it is indexed just fine on Google. These are the steps I've tried: The website is verified in Bing Webmaster Tools and successfully submitted the sitemap. I tested the URL to ensure that Bingbot is allowed to crawl the site I submitted URLs to Bing via the URL Submission tool There isn't a "noindex" on the site preventing it from being indexed When I do a URL Inspection, an error message comes up saying "The inspected URL is known to Bing but has some issues which are preventing us from serving it to our users. We recommend you to follow Bing Webmaster Guidelines." I contacted Bing to ask whether the website was removed in error, but received a reply that the website doesn't comply with Bing's quality guidelines, but they wouldn't go into detail as to which guidelines the website isn't meeting. The website URL is https://www.pardeehospital.org. Can anyone offer any advice or insight as to why Bing won't index our site? Thank you!

SEO on Jobs sites: how to deal with expired listings with "Google for Jobs" around
Dear community, When dealing with expired job offers on jobs sites from a SEO perspective, most practitioners recommend to implement 301 redirects to category pages in order to keep the positive ranking signals of incoming links. Is it necessary to rethink this recommendation with "Google for Jobs" is around? Google's recommendations on how to handle expired job postings does not include 301 redirects. "To remove a job posting that is no longer available: Remove the job posting from your sitemap. Do one of the following: Note: Do NOT just add a message to the page indicating that the job has expired without also doing one of the following actions to remove the job posting from your sitemap. Remove the JobPosting markup from the page. Remove the page entirely (so that requesting it returns a 404 status code). Add a noindex meta tag to the page." Will implementing 301 redirects the chances to appear in "Google for Jobs"? What do you think?

My "search visibility" went from 3% to 0% and I don't know why.
My search visibility on here went from 3.5% to 3.7% to 0% to 0.03% and now 0.05% in a matter of 1 month and I do not know why. I make changes every week to see if I can get higher on google results. I do well with one website which is for a medical office that has been open for years. This new one where the office has only been open a few months I am having trouble. We aren't getting calls like I am hoping we would. In fact the only one we did receive I believe is because we were closest to him in proximity on google maps. I am also having some trouble with the "Links" aspect of SEO. Everywhere I see to get linked it seems you have to pay. We are a medical office we aren't selling products so not many Blogs would want to talk about us. Any help that could assist me with getting a higher rank on google would be greatly appreciated. Also any help with getting the search visibility up would be great as well.

Using a lot of "Read More" Hidden text
My site has a LOT of "read more" and when a user click they will see a lot of text. "read more" is dark blue bold and clear to the user. It is the perfect for the user experience, since right below I have pictures and videos which is what most users want. Question: I expect few users will click "Read more" (however, some users will appreciate chance to read and learn more) and I wonder if search engines may think I am hiding text and this is a risky approach or simply discount the text as having zero value from an SEO perspective? Or, equally important: If the text was NOT hidden with a "Read more" would the text actually carry more SEO value than if it is hidden under a "read more" even though users will NOT read the text anyway? If yes, reason may be: when the text is not hidden, search engines cannot see that users are not reading it and the text carry more weight from an SEO perspective than pages where text is hidden under a "Read more" where users rarely click "read more".
