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="prev" / "next"
Hi guys, The tech department implemented rel="prev" and rel="next" on this website a long time ago.
Intermediate & Advanced SEO | | AdenaSEO
We also added a canonical tag to the 'own' page. We're talking about the following situation: https://bit.ly/2H3HpRD However we still see a situation where a lot of paginated pages are visible in the SERP.
Is this just a case of rel="prev" and "next" being directives to Google?
And in this specific case, Google deciding to not only show the 1st page in the SERP, but still show most of the paginated pages in the SERP? Please let me know, what you think. Regards,

Putting "noindex" on a page that's in an iframe... what will that mean for the parent page?
If I've got a page that is being called in an iframe, on my homepage, and I don't want that called page to be indexed.... so I put a noindex tag on the called page (but not on the homepage) what might that mean for the homepage? Nothing? Will Google, Bing, Yahoo, or anyone else, potentially see that as a noindex tag on my homepage?

Should I NOFOLLOW my "Add To Cart" buttons?
Hello and Merry Christmass Should I NOFOLLOW my "Add To Cart" buttons? My e-commerce site has hundreds of products. Content wise, there is no real value to the reader on that page (besides for some testimonials and "why here" sentences). So it is not a page you'd want / expect to find in the SERPs. Also, with hundreds of links pointing to this page it would be "stronger" than other important pages which doesn't make sense. Last but not least, if I have limited time that the bots are on my site, why keep sending them to a non important page. This is why I am leaning to nofollowing the "add to cart" buttons and looking for reinforcements. Thanks

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,

Do links to PDF's on my site pass "link juice"?
Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use. The great SEO side of this is that they link to my site. The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files. So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site. So do I get any benefit from these great links? If not, does anybody have any suggestions on how I could get credit for them. Keep in mind that editing the PDF's are not allowed by the government. Thanks.

Is it better "nofollow" or "follow" links to external social pages?
Hello, I have four outbound links from my site home page taking users to join us on our social Network pages (Twitter, FB, YT and Google+). if you look at my site home page, you can find those 4 links as 4 large buttons on the right column of the page: http://www.virtualsheetmusic.com/ Here is my question: do you think it is better for me to add the rel="nofollow" directive to those 4 links or allow Google to follow? From a PR prospective, I am sure that would be better to apply the nofollow tag, but I would like Google to understand that we have a presence on those 4 social channels and to make clearly a correlation between our official website and our official social channels (and then to let Google understand that our social channels are legitimate and related to us), but I am afraid the nofollow directive could prevent that. What's the best move in this case? What do you suggest to do? Maybe the nofollow is irrelevant to allow Google to correlate our website to our legitimate social channels, but I am not sure about that. Any suggestions are very welcome. Thank you in advance!
