Two different canonical tags on one page
-
Due to an error, some of my pages now have two canonical tags on them. One is correct and the other goes to a nonsense URL (404 page).
I know I should ideally remove the incorrect ones, but it's a big manual job. Are they doing any harm? Can I just leave them there and let Google figure it out?
The correct ones are higher up in the code. Will this make a difference?
Any help appreciated.

Unfortunately, what Google can do and what they actually do can really vary. If you're mixing signals and doubling up the canonicals, the odds that they'll get it right are pretty low, in my experience. I think it's worth the fix, if these are traffic-generating pages.

You should certainly fix this. You don't want google having to guess what you are trying to tell them. For the most part they will probably get it right, especially in your case with the 404s. But if this is occurring too frequently then they may begin to ignore your canonicals all together. Or worse, you may loose some google trust.
I'd put this on my fix it list.

Thanks Scott. It's only wrong on a few hundred pages and they're all quite deep. If it were wrong on the important pages I'd fix it.

You should change it, I'm no canonical expert, but the whole point of having it is to tell google how you want it to show, ex. www.yoursite.com or yoursite.com. If your not going to change it for all of your pages then at least do it for your home page as this is the one that usually gets the most attention.
-
Well that's good news. Think I'll just leave them there then. Thanks!

This is stright from Google Webmasters:
"What happens if rel="canonical" points to a non-existent page? Or if more than one page in a set is specified as the canonical version?
We'll do our best to algorithmically determine an appropriate canonical page, just as we've done in the past."

How long does it take for canonical tags to work
How long on average does it take for a canonical tag to work? Understand that canonicals are just a suggestion, but after adding a canonical tag and submitting the page via Google fetch, assuming Google follows the canonical, would you expect it to work after a day or two or does it take longer? We added canonicals to old PPC landing pages that are ranking organically, though our new landing pages (which we want to rank organically) are not identical and have a bit more content/features. They are similar though. Canonicals were added to the old pages (pointing to new pages) and requested indexing via search console. Old pages are still ranking and new pages not so much. FYI we are unable to 301 old PPC pages due to other non negotiable reasons unfortunately. Thanks.

Two Dentists, Same Address, Same Phone, Different Business Names
Hi Everyone, I've been looking into this situation for quite a while, but most posts/information on this topic seem to be from at least 1-2 years ago. I'm currently working with a dentist who just moved into the same suite as another dentist who has been working there for years. They each have the same address and same suite number, the same phone number, but each own their own respective practice and have their own patients. To make things even more complicated, the dentist that has been working there for years uses his name as a business name, while the new dentist has a business name differing from her actual name. I'm not exactly sure how to go about optimizing the new dentist's local presence, but the only thing I can think of doing is try to recommend having the suite split into Suite #-A and Suite #-B and seeing if it's possible to add a second phone number for the new dentist. Please let me know your thoughts, and if you've seen this topic come up in the past, I would love to get pointed in the right direction. Thanks for all your help!

Product Pages Outranking Category Pages
Hi, We are noticing an issue where some product pages are outranking our relevant category pages for certain keywords. For a made up example, a "heavy duty widgets" product page might rank for the keyword phrase Heavy Duty Widgets, instead of our Heavy Duty Widgets category page appearing in the SERPs. We've noticed this happening primarily in cases where the name of the product page contains an at least partial match for the desired keyword phrase we want the category page to rank for. However, we've also found isolated cases where the specified keyword points to a completely irrelevent pages instead of the relevant category page. Has anyone encountered a similar issue before, or have any ideas as to what may cause this to happen? Let me know if more clarification of the question is needed. Thanks!

Splitting Page Authority with two URLs for the same page.
Hello guys, My website is currently holding two different URLs for the same page and I am under the impression such set up is dividing my Page Authority and Link Juice. We currently have the following page with both URLs below: www.wbresearch.com/soldiertechnologyusa/home.aspx
Technical SEO | | JoaoPdaCosta-WBR
www.wbresearch.com/soldiertechnologyusa/ Analysing the page authority and backlinks I identified that we are splitting the amount of backlinks (links from sites, social media and therefore authority). "/home.aspx"
PA: 67
Linking Root Domains: 52
Total Links: 272 "/"
PA: 64
Linking Root Domains: 29
Total Links: 128 I am under the impression that if the URLs were the same we would maximise our backlinks and therefore page authority. My Question: How can I fix this? Should I have a 301 redirect from the page "/" to the "/home.aspx" therefore passing the authority and link juice of “/” directly to “/homes.aspx”? Trying to gather thoughts and ideas on this, suggestions are much appreciated? Thanks!0 -
Home Page .index.htm and .com Duplicate Page Content/Title
I have been whittling away at the duplicate content on my clients' sites, thanks to SEOmoz's pro report, and have been getting push back from the account manager at register.com (the site was built here and the owner doesn't want to move it). He says these are the exact same page and he can't access one to redirect to the other. Any suggestions? The SEOmoz report says there is duplicate content on both these urls: Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/index.htm Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/ Your help is greatly appreciated!

Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
