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,

"Avoid Too Many Internal Links" when you have a mega menu
Using the on-page grader and whilst further investigating internal linking, I'm concerned that as the ecommerce website has a very link heavy mega menu the rule of 100 may be impeding on the contextual links we're creating. Clearly we don't want to no-follow our entire menu. Should we consider no-indexing the third-level- for example short sleeve shirts here... Clothing > Shirts > Short Sleeve Shirts What about other pages we're don't care to index anyway such as the 'login page' the 'cart' the search button? Any thoughts appreciated.

Canonical and Alternate Advice
At the moment for most of our sites, we have both a desktop and mobile version of our sites. They both show the same content and use the same URL structure as each other. The server determines whether if you're visiting from either device and displays the relevant version of the site. We are in a predicament of how to properly use the canonical and alternate rel tags. Currently we have a canonical on mobile and alternate on desktop, both of which have the same URL because both mobile and desktop use the same as explained in the first paragraph. Would the way of us doing it at the moment be correct?

What is best practice for "Sorting" URLs to prevent indexing and for best link juice ?
We are now introducing 5 links in all our category pages for different sorting options of category listings.
Intermediate & Advanced SEO | | lcourse
The site has about 100.000 pages and with this change the number of URLs may go up to over 350.000 pages.
Until now google is indexing well our site but I would like to prevent the "sorting URLS" leading to less complete crawling of our core pages, especially since we are planning further huge expansion of pages soon. Apart from blocking the paramter in the search console (which did not really work well for me in the past to prevent indexing) what do you suggest to minimize indexing of these URLs also taking into consideration link juice optimization? On a technical level the sorting is implemented in a way that the whole page is reloaded, for which may be better options as well.0 -
Should pages with rel="canonical" be put in a sitemap?
I am working on an ecommerce site and I am going to add different views to the category pages. The views will all have different urls so I would like to add the rel="canonical" tag to them. Should I still add these pages to the sitemap?

Pipe ("|") in my website's title is being replaced with ":" in Google results
Hi , One of the websites I'm promoting and working on is www.pau-brasil.co.il.
Intermediate & Advanced SEO | | Kadel
It's wordpress-based website and as you can see the html's Title is "PauBrasil | some hebrew slogan".
(Screenshot: http://i.imgur.com/2f80EEY.gif)
When I'm searching for "PauBrasil" (Which is the brand's name) , one of the results google shows is "PauBrasil: Some Hebrew Slogan" (Screenshot: http://i.imgur.com/eJxNHrO.gif ) Why does the pipe is being replaced with ":" ?
And not just that , as you can see there's a "blank space" missing between the the ":" to the slogan.
(note: the websites has been indexed by google crawler at least 4 times so I find it hard to believe it can be the reason) I've keep on looking and found out that there's another page in that website with the exact same title
but when I'm looking for it in google , it shows the title as it really is , with pipe. ("|").
(Screenshot: http://i.imgur.com/dtsbZV2.gif) Have you ever encountered something like that?
Can it be that the duplicated title cause that weird "replacement"? Thanks in advance,

Can too many "noindex" pages compared to "index" pages be a problem?
Hello, I have a question for you: our website virtualsheetmusic.com includes thousands of product pages, and due to Panda penalties in the past, we have no-indexed most of the product pages hoping in a sort of recovery (not yet seen though!). So, currently we have about 4,000 "index" page compared to about 80,000 "noindex" pages. Now, we plan to add additional 100,000 new product pages from a new publisher to offer our customers more music choice, and these new pages will still be marked as "noindex, follow". At the end of the integration process, we will end up having something like 180,000 "noindex, follow" pages compared to about 4,000 "index, follow" pages. Here is my question: can this huge discrepancy between 180,000 "noindex" pages and 4,000 "index" pages be a problem? Can this kind of scenario have or cause any negative effect on our current natural SEs profile? or is this something that doesn't actually matter? Any thoughts on this issue are very welcome. Thank you! Fabrizio

Removing Dynamic "noindex" URL's from Index
6 months ago my clients site was overhauled and the user generated searches had an index tag on them. I switched that to noindex but didn't get it fast enough to avoid being 100's of pages indexed in Google. It's been months since switching to the noindex tag and the pages are still indexed. What would you recommend? Google crawls my site daily - but never the pages that I want removed from the index. I am trying to avoid submitting hundreds of these dynamic URL's to the removal tool in webmaster tools. Suggestions?
