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."

Hope that helps

Google keeps marking different pages as duplicates
My website has many pages like this: mywebsite/company1/valuation mywebsite/company2/valuation mywebsite/company3/valuation mywebsite/company4/valuation ... These pages describe the valuation of each company. These pages were never identical but initially, I included a few generic paragraphs like what is valuation, what is a valuation model, etc... in all the pages so some parts of these pages' content were identical. Google marked many of these pages as duplicated (in Google Search Console) so I modified the content of these pages: I removed those generic paragraphs and added other information that is unique to each company. As a result, these pages are extremely different from each other now and have little similarities. Although it has been more than 1 month since I made the modification, Google still marks the majority of these pages as duplicates, even though Google has already crawled their new modified version. I wonder whether there is anything else I can do in this situation? Thanks

Quick Fix to "Duplicate page without canonical tag"?
When we pull up Google Search Console, in the Index Coverage section, under the category of Excluded, there is a sub-category called ‘Duplicate page without canonical tag’. The majority of the 665 pages in that section are from a test environment. If we were to include in the robots.txt file, a wildcard to cover every URL that started with the particular root URL ("www.domain.com/host/"), could we eliminate the majority of these errors? That solution is not one of the 5 or 6 recommended solutions that the Google Search Console Help section text suggests. It seems like a simple effective solution. Are we missing something?

Do you need a canonical tag for search and filter pages?
Hi Moz Community, We've been implementing new canonical tags for our category pages but I have a question about pages that are found via search and our filtering options. Would we still need a canonical tag for pages that show up in search + a filter option if it only lists one page of items? Example below. www.uncommongoods.com/search.html/find/?q=dog&exclusive=1 Thanks!

Blog Page Titles - Page 1, Page 2 etc.
Hi All, I have a couple of crawl errors coming up in MOZ that I am trying to fix. They are duplicate page title issues with my blog area. For example we have a URL of www.ourwebsite.com/blog/page/1 and as we have quite a few blog posts they get put onto another page, example www.ourwebsite.com/blog/page/2 both of these urls have the same heading, title, meta description etc. I was just wondering if this was an actual SEO problem or not and if there is a way to fix it. I am using Wordpress for reference but I can't see anywhere to access the settings of these pages. Thanks

Should I noindex my blog's tag, category, and author pages
Hi there, Is it a good idea to no index tag, category, and author pages on blogs? The tag pages sometimes have duplicate content. And the category and author pages aren't really optimized for any search term. Just curious what others think. Thanks!

Duplicate content on Product pages for different product variations.
I have multiple colors of the same product, but as a result I'm getting duplicate content warnings. I want to keep these all different products with their own pages, so that the color can be easily identified by browsing the category page. Any suggestions?

Postcard Advantages should "postcard" be repeated in the URL and Page Title? and in this example should each of the 5 children link back directly to the parent or would it be better to "daisy chain" them using each as parent for the next?0
