      Hi everyone,

      I'm driving myself insane trying to figure this one out and am hoping someone has more technical chops than I do. Here's the situation...

      I'm getting duplicate canonical tags on my pages and posts, one is inside of the WordPress SEO (plugin) commented section, and the other is elsewhere in the header. I am running the latest version of WordPress 3.1.3 and the Genesis framework.

      After doing some testing and adding the following filters to my functions.php:

      <code>remove_action('wp_head', 'genesis_canonical');
      remove_action('wp_head', 'rel_canonical');</code>
      

      ... what I get is this:

      With the plugin active + NO "remove action" - duplicate canonical tags
      With the plugin disabled + NO "remove action" - a single canonical tag
      With the plugin disabled + A "remove action" - no canonical tag

      I have tried using only one of these remove_actions at a time, and then combining them both. Regardless, as long as I have the plugin active I get duplicate canonical tags.

      Is this a bug in the plugin, perhaps somehow enabling the canonical functionality of WordPress?

      Thanks for your help everyone.

        Hi Matthew - not that I saw. It appears to be a feature built in and non-configurable. Lot's of indexation options but nothing for canonicals.

          Hi,

          DOes the plugin have an option to disable canonical URL's?  For example in platinum SEO its just a tick box, when its ticked the plugin and WP itself adds the canonical tag, untick it and just wordpress adds it automatically.

            Canonical or hreflang?

            I have four English sites for four different countries, UK, Ireland, Australia and New Zealand and I want to share some content between the sites. On the pages that share the content, which is essentially exactly the same on all 4 sites, do I use the hreflang tags like: or do I add a canonical tag to the other three pointing to the "origin", which would be the UK site? I believe it is best practice to use one or the other, but I'm not sure which make sense in this situation.

            Duplicate, submitted URL not selected as canonical

            Hi all, A number of our pages have dropped out of search rankings. It seems they are being marked as "Duplicate, submitted URL not selected as canonical" However, the page Google is choosing as the canonical is totally different - different headings, titles, metadata, content on the page. We are completely mystified as to why this is happening. If anyone can shed any light, it would be hugely appreciated! Example URL is this one:
            https://www.vouchedfor.co.uk/IFA-financial-advisor-mortgage/london Which Google seems to think is a duplicate of this: https://www.vouchedfor.co.uk/solicitor/london

            Trailing slash URLs and canonical links

            Hi, I've seen a fair amount of topics speaking about the difference between domain names ending with or without trailing slashes, the impact on crawlers and how it behaves with canonical links.
            However, it sticks to domain names only.
            What about subfolders and pages then? How does it behaves with those? Say I've a site structured like this:
            https://www.domain.com
            https://www.domain.com/page1 And for each of my pages, I've an automatic canonical link ending with a slash.
            Eg. rel="canonical" href="https://www.domain.com/page1/" /> for the above page. SEM Rush flags this as a canonical error. But is it exactly?
            Are all my canonical links wrong because of that slash? And as subsidiary question, both domain.com/page1 and domain.com/page1/ are accessible. Is it this a mistake or it doesn't make any difference (I've read that those are considered different pages)? Thanks!
            G

            Category URL Pagination where URLs don't change between pages

            Hello, I am working on an e-commerce site where there are categories with multiple pages. In order to avoid pagination issues I was thinking of using rel=next and rel=prev and cannonical tags. I noticed a site where the URL doesn't change between pages, so whether you're on page 1,2, or 3 of the same category, the URL doesn't change. Would this be a cleaner way of dealing with pagination?

            301 redirect: canonical or non canonical?

            Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

            Duplicate Content

            We have a ton of duplicate content/title errors on our reports, many of them showing errors of: http://www.mysite.com/(page title) and http://mysite.com/(page title) Our site has been set up so that mysite.com 301 redirects to www.mysite.com (we did this a couple years ago). Is it possible that I set up my campaign the wrong way in SEOMoz? I'm thinking it must be a user error when I set up the campaign since we already have the 301 Redirect. Any advice is appreciated!

            Old URL redirect to New URL

            Alright I did something dumb a year a go and I'm still paying for it. I changed my hyphenated URL to the non-hyphenated version when I redesigned my website. I say it was dumb because I lost most of my link juice even though I did 301 redirects (via the htaccess file) for almost all of the pages I could find in Google's index. Here's my problem. My new site took a huge hit in traffic (down 60%) when I made the change and even though I've done thousands of redirects my old site is still showing up in the SERPS and send much if not most of my traffic. I don't want to take the old site down in fear it will kill all of my traffic. What should I do? Is there a better method I should explore then 301 redirects? Could the other site be affecting my current rank since it's still there? (FYI...both sites are built on the WP platform). Any help or ideas are greatly appreciated. Thank you! Joe
