          I found a little difficult for me to do a canonical tag in my PHP.

          On-Page Report Card

          We check to make sure that IF you use canonical URL tags, it points to the right page. If the canonical tag points to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. If you've not made this page the rel=canonical target, change the reference to this URL. NOTE: For pages not employing canonical URL tags, this factor does not apply.

          I don't know how to tidy my PHP

          Any suggestion.

            Thanks Shane,

            That was very simple and to the point.  I am doing SEO on a php site where there's a header and a footer and I didin't know how to add the canoical tag to the header correctly and the On page.  Thanks again.

            Benny

              Is this a CMS, or are you trying to make the canonical only impact certain pages or conditions? The canonical tag is just an HTML tag, in the header. It doesn't really need special code, unless the target of the canonical has to be created dynamically. Unfortunately, then the solution depends entirely on your implementation (it's not one-sized-fits-all across all PHP sites).

              If you could describe the structure of the site a bit (example URLs and how they're created) without revealing the site, that could help us pin it down.

                Hi,

                In my site, I use a php expression - as such -

                header.php -

                On page -

                $canonical = "http://www.domain.com";

                Here is a recent Blog Post if the above code does not help

                  URL has caps, but canonical does not. Now what?

                  Hi, Just started working with a site that has the occasional url with a capital, but then the url in the canonical as lower case. Neither, when entered in a browser, resolves to the other. It's a Shopify site. What do you think I should do?

                  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?

                  The Mysterious Case of Pagination, Canonical Tags

                  Hey guys, My head explodes when I think of this problem. So I will leave it to you guys to find a solution... My root domain (xxx.com) runs on WordPress platform. I use Yoast SEO plugin. The next page of root domain -- page/2/ -- has been canonicalized to the same page -- page/2/ points to page/2/ for example. The page/2/ and remaining pages also have this rel tags: I have also added "noindex,follow" to page/2/ and further -- Yoast does this automatically. Note: Yoast plugin also adds canonical to page/2/...page/3/ automatically. Same is the case with category pages and tag pages. Oh, and the author pages too -- they all have self-canonicalization, rel prev & rel next tags, and have been "noindex, followed." Problem: Am I doing this the way it should be done? I asked a Google Webmaster employee on rel next and prev tags, and this is what she said: "We do not recommend noindexing later pages, nor rel="canonical"izing everything to the first page." (My bad, last year I was canonicalizing pages to first page). One of the popular blog, a competitor, uses none of these tags. Yet they rank higher. Others following this format have been hit with every kind of Google algorithm I could think of. I want to leave it to Google to decide what's better, but then again, Yoast SEO plugin rules my blog -- okay, let's say I am a bad coder. Any help, suggestions, and thoughts are highly appreciated. 🙂 Update 1: Paginated pages -- including category pages and tag pages -- have unique snippets; no full-length posts. Thought I'd make that clear.

                  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!

                  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

                  Robots.txt and canonical tag

                  In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?

                  Duplicate canonical URLs in WordPress

                  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. Robert Dempsey
