          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.

              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

                  Should I use a canonical URL for images uploaded to a blog post in Wordpress?

                  Hi, I have a wordpress website that has articles/news posts witch contain imagery. I've noticed that in the Media Library, when you upload an image to a blog post it generates a new permalink ...article-name/article-image-01.jpg I have Yoast SEO plugin and have the option to set a canonical URL for this image. Should I point it back to the actual article? Thanks for any helpers with this.

                  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!

                  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 H2 tags carry more weight than h4 tags?

                  Of course H tags are key signals for relevance in search.  Does an h2 tag send a significantly "louder" signal than an h4 tag?

                  Special characters in URL

                  Hi There, We're in the process of changing our URL structure to be more SEO friendly. Right now I'm struggling to find a good way to handle slashes that are part of a targeted keyword. For example, if I have a product page and my product title is "1/2 ct Diamond Earrings in 14K Gold" which of the following URLs is the right way to go if I'm targeting the product title as the search keyword? example.com/jewelry/1-2-ct-diamond-earrings-in-14k-gold example.com/jewelry/12-ct-diamond-earrings-in-14k-gold example.com/jewelry/1_2-ct-diamond-earrings-in-14k-gold example.com/jewelry/1%2F2-ct-diamond-earrings-in-14k-gold Thanks!

                  Geotargeting duplicate content to different regions - href and canonical tag confusion

                  If you duplicate content onto a sub-folder for say a new US geotargeted site (to target kw spelling differences) and, in addition to GWT geotargeting settings, implement the 'Canonical' and 'Hreflang' tags on these new pages to show G different region and language version (en-us).  Then does the original/main site similar pages also need to have canonical and href tags ? The main/original sites page I don't really want to target a specific country (although existing signals (hosting etc) will be UK (primary target of main site) but pages show up in other country searches too (which we want). Im  presuming fine to leave the original/main site as it currently is although wording in google blog/webmaster central articles etc are a bit confusing hence why im asking for anyone elses opinion/input on this. Also is there are any benefit (or just best practice) to use 'www.example.com/en-us/...' in the subdirectory URL as opposed to just 'www.example.com/us/' many thanks in advance to any commentators 🙂

                  Should there be a canonical tag on my 404 error page?

                  In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
