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,

[Very Urgent] More 100 "/search/adult-site-keywords" Crawl errors under Search Console
I just opened my G Search Console and was shocked to see more than 150 Not Found errors under Crawl errors. Mine is a Wordpress site (it's consistently updated too): Here's how they show up: Example 1: URL: www.example.com/search/adult-site-keyword/page2.html/feed/rss2 Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword/page2.html Example 2 (this surprised me the most when I looked at the linked from data): URL: www.example.com/search/adult-site-keyword-2.html/page/3/ Linked From: www.example.com/search/adult-site-keyword-2.html/page/2/ (this is showing as if it's from our own site) http://a-spammy-adult-site.com/search/adult-site-keyword-2.html Example 3: URL: www.example.com/search/adult-site-keyword-3.html Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword-3.html How do I address this issue?

"sex" in non-adult domain name
I have a client with a domain that has "sex" in the domain name. For example, electronicsexpo.com. The domain ranks for a few keywords related to the services offered. It is an old domain that has been online for over 10 years. It ranks well for local keywords. No real SEO effort has been made on this domain, so it is rather a clean slate. I am going to be doing SEO on this site. Will the fact that the word "sex" exists in the name have any sort of negative consequence. There is ABSOLUTELY NOTHING adult related or pornographic on this site. I would think that search engines are sophisticated enough to differentiate, but would potential customers with things like parental filters be blocked from viewing content? Is this hurtful in anyway? If so, would I be better off changing domain names? TIA

When i search for my domain name - google asks "did you mean" - why?
Hi all, I just noticed something quite odd - if i do a search for my domain name (see: http://goo.gl/LBc1lz) google shows my domain as first result, but it also asks "did i mean" and names another website with very similar name. the other site has far lower PA/DA according to Moz, any ideas why google is doing this? and more inportantly how i could stop it? please advise James

When is it recommended to use a self referencing rel "canonical"?
In what type of a situation is it the best type of practice to use a self referencing rel "canonical" tag? Are there particular practices to be cautious of when using a self referencing rel "canonical" tag? I see this practice used mainly with larger websites but I can't find any information that really explains when is a good time to make use of this practice for SEO purposes. Appreciate all feedback. Thank you in advance.

Do I need to use rel="canonical" on pages with no external links?
I know having rel="canonical" for each page on my website is not a bad practice... but how necessary is it for pages that don't have any external links pointing to them? I have my own opinions on this, to be fair - but I'd love to get a consensus before I start trying to customize which URLs have/don't have it included. Thank you.

Is it a bad idea to have a "press" page and link to press mentions of our company?
We've recently been getting quite a bit of press. Would it be wise to create a "press" page and link to mentions of us or would this devalue the links on the press pages as Google may think they reciprocal?

Canonical VS Rel=Next & Rel=Prev for Paginated Pages
I run an ecommerce site that paginates product pages within Categories/Sub-Categories. Currently, products are not displayed in multiple categories but this will most likely happen as time goes on (in Clearance and Manufacturer Categories). I am unclear as to the proper implementation of Canonical tags and Rel=Next & Rel=Prev tags on paginated pages. I do not have a View All page to use as the Canonical URL so that is not an option. I want to avoid duplicate content issues down the road when products are displayed in multiple categories of the site and have Search Engines index paginated pages. My question is, should I use the Rel=Next & Rel=Prev tags on paginated pages as well as using Page One as the Canonical URL? Also, should I implement the Canonical tag on pages that are not yet paginated (only one page)?
