      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.

            What could cause Google to not honor canonical URLs?

            I have a strange situation on a website, when I do a Google query of site:example.com all the top indexed results appear to be queries that users can perform on the website. So any random term the user searches for on the website for some reason is causing the search result page to get indexed - like example.com/search/query/random-keywords However, the search results page has a canonical tag on it that points to example.com/search, but that doesn't seem to be doing anything. Any thoughts or ideas why this could be happening?

            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!

            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?

            Product Variations (rel=canonical or 301) & Duplicate Product Descriptions

            Hi All, Hoping for a bit of advice here please, I’ve been tasked with building an e-commerce store and all is going well so far. We decided to use Wordpress with Woocommerce as our shop plugin. I’ve been testing the CSV import option for uploading all our products and I’m a little concerned on two fronts: - Product Variations Duplicate content within the product descriptions **Product Variations: - ** We are selling furniture that has multiple variations (see list below) and as a result it creates c.50 product variations all with their own URL’s. Facing = Left, Right Leg style = Round, Straight, Queen Ann Leg colour = Black, White, Brown, Wood Matching cushion = Yes, No So my question is should I 301 re-direct the variation URL’s to the main product URL as from a user perspective they aren't used (we don't have images for each variation that would trigger the URL change, simply drop down options for the user to select the variation options) or should I add the rel canonical tag to each variation pointing back to the main product URL. **Duplicate Content: - ** We will be selling similar products e.g. A chair which comes in different fabrics and finishes, but is basically the same product.  Most, if not all of the ‘long’ product descriptions are identical with only the ‘short’ product descriptions being unique. The ‘long’ product descriptions contain all the manufacturing information, leg option/colour information, graphics, dimensions, weight etc etc. I’m concerned that by having 300+ products all with identical ‘long’ descriptions its going to be seen negatively by google and effect the sites SEO. My question is will this be viewed as duplicate content?  If so, are there any best practices I should be following for handling this, other than writing completely unique descriptions for each product, which would be extremely difficult given its basically the same products re-hashed. Many thanks in advance for any advice.

            Numbers in URL

            Hey guys! Need your many awesome brains. 🙂 This may be a very basic question but am hoping you can help me out with some insights beyond "because Google says it's better". 🙂 I only recently started working with SEO, and I work for a SaaS website builder company that has millions of open/active user sites, and all our user sites URLs, instead of www.mydomainname.com/gallery or myusername.simplesite.com/about, we use numbers, so www.mysite.com/453112 or myusername.simplesite.com/426521 The Sales manager has asked me to figure out if it will pay off for us in terms of traffic (other benefits?) to change it from the number system to the "proper" and right way of setting up these URLs. He's looking for rather concrete answers, as he usually sits with paid search and is therefore used to the mindset of "if we do x it will yield us y in z months". I'm finding it quite difficult to find case studies/other concrete examples beyond the generic, vague implication that it will simply be "better" (when for example looking at SEO checklists and search engine guidelines). Will it make a difference? How so? I have to convince our developers of the importance and priority of this adjustment, or it will just drown in the many projects they already have. So truly, any insights would be so very welcome. Thank you!

            Do canonical tags pass all of the link juice onto the URL they point to?

            I have an ecommerce website where the category pages have various sorting and paging options which add a suffix to the URLs. My site is setup so the root category URL, domain.com/category-name, has a canonical tag pointing to domain.com/category-name/page1/price however all links, both interner & external, point to the former (i.e. domain.com/category-name). I would like to know whether all of the link juice is being passed onto the canonical tag URL? Otherwise should I change the canonical tag to point the other way? Thanks!

            Duplicate title-tags with pagination and canonical

            Some time back we implemented the Google recommendation for pagination (the rel="next/prev"). GWMT now reports 17K pages with duplicate title-tags (we have about 1,1m products on our site and about 50m pages indexed in Google) As an example we have properties listed in various states and the category title would be "Properties for Sale in [state-name]". A paginated search page or browsing a category (see also http://searchengineland.com/implementing-pagination-attributes-correctly-for-google-114970) would then include the following: The title for each page is the same - so to avoid the duplicate title-tags issue, I would think one would have the following options: Ignore what Google says Change the canonical to http://www.site.com/property/state.html (which would then only show the first XX results) Append a page number to the title "Properties for Sale in [state-name] | Page XX" Have all paginated pages use noindex,follow - this would then result in no category page being indexed Would you have the canonical point to the individual paginated page or the base page?

            Redirect non-www if using canonical url?

            I have setup my website to use canonical urls on each page to point to the page i wish Google to refer to. At the moment, my non-www domain name is not redirected to www domain. Is this required if i have setup the canonical urls? This is the tag i have on my index.php page rel="canonical" href="http://www.mydomain.com.au" /> If i browse to http://mydomain.com.au should the link juice pass to http://www.armourbackups.com.au? Will this solve duplicate content problems? Thanks
