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,

Canonical Chain
This is quite advanced so maybe Rand can give me an answer? I often have seen questions surrounding a 301 chain where only 85% of the link juice is passed on to the first target and 85% of that to the next one, up to three targets. But how about a canonical chain? What do I mean by this:? I have a client who sells lighting so I will use a real example (sans domain) I don't want 'new-product' pages appearing in SERPS. They dilute link equity for the categories they replicate and often contain identical products to the main categories and subcategories. I don't want to no index them all together I'd rather tell Google they are the same as the higher category/sub category. (discussion whether a noindex/follow tag would be better?) If I canonicalize new-products/ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 to /ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 I then subsequently discover that everything in kitchen-ceiling-lights-c217 is already in /kitchen-lighting-c17 and I decide to canonicalize those two - so I place a /kitchen-lighting-c17 canonical on /kitchen-ceiling-lights-c217. Then what happens to the new-products canonical? Is it the same rule - does it pass 85% of link equity back to the non new-product URL and 85% of that back to the category? does it just not work? or should I do noindexi/follow Now before you jump in: Let's assume these are done over a period of time because the obvious answer is: Canonicalize both back to /ceiling-lights-c1/kitchen-lighting-c17 I know that and that is not what I am asking. What if they are done in a sequence what is the real result? I don't want to patronise anyone but please read this carefully before giving an answer. Regards Nigel Carousel Projects.

Can an "Event" in Structured Data For Google Be A Webinar?
I have a client who is has structured data for live business webinars. Google's documentation seems to talk more about music and tickets than this kind of thing. At the same time, we get an error in search console for "Name" and location, which they list as "webinar." Should I removed this failed structured data attempt or is there a way to fix it? Thanks!

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?

How do I get rel='canonical' to eliminate the trailing slash on my home page??
I have been searching high and low. Please help if you can, and thank you if you spend the time reading this. I think this issue may be affecting most pages. SUMMARY: I want to eliminate the trailing slash that is appended to my website. SPECIFIC ISSUE: I want www.threewaystoharems.com to showing up to users and search engines without the trailing slash but try as I might it shows up like www.threewaystoharems.com/ which is the canonical link. WHY? and I'm concerned my back-links to the link without the trailing slash will not be recognized but most people are going to backlink me without a trailing slash. I don't want to loose linkjuice from the people and the search engines not being in consensus about what my page address is. THINGS I"VE TRIED: (1) I've gone in my wordpress settings under permalinks and tried to specify no trailing slash. I can do this here but not for the home page. (2) I've tried using the SEO by yoast to set the canonical page. This would work if I had a static front page, but my front page is of blog posts and so there is no advanced page settings to set the canonical tag. (3) I'd like to just find the source code of the home page, but because it is CSS, I don't know where to find the reference. I have gone into the css files of my wordpress theme looking in header and index and everywhere else looking for a specification of what the canonical page is. I am not able to find it. I'm thinking it is actually specified in the .htaccess file. (4) Went into cpanel file manager looking for files that contain Canonical. I only found a file called canonical.php . the only thing that seemed like it was worth changing was changing line 139 from $redirect_url = home_url('/'); to $redirect_url = home_url(''); nothing happened. I'm thinking it is actually specified in the .htaccess file. (5) I have gone through the .htaccess file and put thes 4 lines at the top (didn't redirect or create the proper canonical link) and then at the bottom of the file (also didn't redirect or create the proper canonical link) : RewriteEngine on

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

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

What is the best way to optimize/setup a teaser "coming soon" page for a new product launch?
Within the context of a physical product launch what are some ideas around creating a /coming-soon page that "teases" the launch. Ideally I'd like to optimize a page around the product, but the client wants to try build consumer anticipation without giving too many details away. Any thoughts?

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?
