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."

Removing a canonical tag from Pagination pages
Hello, Currently on our site we have the rel=prev/next markup for pagination along with a self pointing canonical via the Yoast Plugin. However, on page 2 of our paginated series, (there's only 2 pages currently), the canonical points to page one, rather than page 2. My understanding is that if you use a canonical on paginated pages it should point to a viewall page as opposed to page one. I also believe that you don't need to use both a canonical and the rel=prev/next markup, one or the other will do. As we use the markup I wanted to get rid of the canonical, would this be correct? For those who use the Yoast Plugin have you managed to get that to work? Thanks!

Can I set a canonical tag to an anchor link?
I have a client who is moving to a one page website design. So, content from the inner pages is being condensed in to sections on the 'home' page. There will be a navigation that anchor links to each relevant section. I am wondering if I should leave the old pages and use rel=canonical to point them to their relevant sections on the new 'home' page rather than 301 them. Thoughts?

Canonical Tag when using Ajax and PhantomJS
Hello, We have a site that is built using an AJAX application. We include the meta fragment tag in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

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!

What's the difference between a category page and a content page
Hello, Little confused on this matter. From a website architectural and content stand point, what is the difference between a category page and a content page? So lets say I was going to build a website around tea. My home page would be about tea. My category pages would be: White Tea, Black Tea, Oolong Team and British Tea correct? ( I Would write content for each of these topics on their respective category pages correct?) Then suppose I wrote articles on organic white tea, white tea recipes, how to brew white team etc...( Are these content pages?) Do I think link FROM my category page ( White Tea) to my ( Content pages ie; Organic White Tea, white tea receipes etc) or do I link from my content page to my category page? I hope this makes sense. Thanks, Bill
