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."

Customer Reviews on Product Page / Pagination / Crawl 3 review pages only
Hi experts, I present customer feedback, reviews basically, on my website for the products that are sold. And with this comes the ability to read reviews and obviously with pagination to display the available reviews. Now I want users to be able to flick through and read the reviews to help them satisfy whatever curiosity they have. My only thinking is that the page that contains the reviews, with each click of the pagination will present roughly the same content. The only thing that changes is the title tags which will contain the number in the H1 to display the page number. I'm thinking this could be duplication but i have yet to be notified by Google in my Search console... Should i block crawlers from crawling beyond page 3 of reviews? Thanks

Should I "no-index" two exact pages on Google results?
Hello everyone, I recently started a new wordpress website and created a static homepage. I noticed that on Google search results, there are two different URLs landing on same content page. I've attached an image to explain what I saw. Should I "no-index" the page url? Google url.JPG In this picture, the first result is the homepage and I try to rank for that page. The last result is landing on same content with different URL. So, should I no-index last result as shown in image?

Do URLs with canonical tags get indexed by Google?
Hi, we re-branded and launched a new website in February 2016. In June we saw a steep drop in the number of URLs indexed, and there have continued to be smaller dips since. We started an account with Moz and found several thousand high priority crawl errors for duplicate pages and have since fixed those with canonical tags. However, we are still seeing the number of URLs indexed drop. Do URLs with canonical tags get indexed by Google? I can't seem to find a definitive answer on this. A good portion of our URLs have canonical tags because they are just events with different dates, but otherwise the content of the page is the same.

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!

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!

Is the Authority of Individual Pages Diluted When You Add New Pages?
I was wondering if the authority of individual pages is diluted when you add new pages (in Google's view). Suppose your site had 100 pages and you added 100 new pages (without getting any new links). Would the average authority of the original pages significantly decrease and result in a drop in search traffic to the original pages? Do you worry that adding more pages will hurt pages that were previously published?

Setting up canonical tags for an old site. I really need advice on that darn backslash / at the end of the homepage URL.

URL query strings and canonical tag
Hi, I have recently been getting my comparison website redesigned and developed onto wordpress and the site is now 90% complete. Part of the redesign has meant that there are now dynamic urls in the format: http://www.mywebsite.com/10-pounds-productss/?display=cost&value=10 I have other pages similar to this but with different content for the different price ranges and these are linked to from the menus: http://www.mywebsite.com/20-pounds-products/?display=cost&value=20 Now my questions are: 1. I am using Joost's All-in-one SEO plugin and this adds a canonical tag to the page that is pointing to http://www.mywebsite.com/10-pounds-products/ which is the permalink. Is this OK as it is or should i change this to http://www.mywebsite.com/10-pounds-products/?display=cost&value=10 2. Which URL will get indexed, what gets shown as the display URL in the SERPs and what page will users land on? I'm a bit confused so apologies if these seem like silly questions. Thanks
