          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

                • Dynamic Canonical Tag for Search Results Filtering Page

                  canonical indexation search page categorization search results crawl

                  Hi everyone, I run a website in the travel industry where most users land on a location page (e.g. domain.com/product/location, before performing a search by selecting dates and times. This then takes them to a pre filtered dynamic search results page with options for their selected location on a separate URL (e.g. /book/results). The /book/results page can only be accessed on our website by performing a search, and URL's with search parameters from this page have never been indexed in the past. We work with some large partners who use our booking engine who have recently started linking to these pre filtered search results pages. This is not being done on a large scale and at present we only have a couple of hundred of these search results pages indexed. I could easily add a noindex or self-referencing canonical tag to the /book/results page to remove them, however it’s been suggested that adding a dynamic canonical tag to our pre filtered results pages pointing to the location page (based on the location information in the query string) could be beneficial for the SEO of our location pages. This makes sense as the partner websites that link to our /book/results page are very high authority and any way that this could be passed to our location pages (which are our most important in terms of rankings) sounds good, however I have a couple of concerns. • Is using a dynamic canonical tag in this way considered spammy / manipulative? • Whilst all the content that appears on the pre filtered /book/results page is present on the static location page where the search initiates and which the canonical tag would point to, it is presented differently and there is a lot more content on the static location page that isn’t present on the /book/results page. Is this likely to see the canonical tag being ignored / link equity not being passed as hoped, and are there greater risks to this that I should be worried about? I can’t find many examples of other sites where this has been implemented but the closest would probably be booking.com. https://www.booking.com/searchresults.it.html?label=gen173nr-1FCAEoggI46AdIM1gEaFCIAQGYARS4ARfIAQzYAQHoAQH4AQuIAgGoAgO4ArajrpcGwAIB0gIkYmUxYjNlZWMtYWQzMi00NWJmLTk5NTItNzY1MzljZTVhOTk02AIG4AIB&sid=d4030ebf4f04bb7ddcb2b04d1bade521&dest_id=-2601889&dest_type=city& Canonical points to https://www.booking.com/city/gb/london.it.html In our scenario however there is a greater difference between the content on both pages (and booking.com have a load of search results pages indexed which is not what we’re looking for) Would be great to get any feedback on this before I rule it out. Thanks!

                  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

                  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?

                  Should I Parent/Child my Website Pages (need help with terminology too)

                  Hello I have a website that I am trying to SEO optimise.
                  The current structure of the site is that all pages are linked directly after the domain:
                  example:   www.domain.com**/page01**  www.domain.com**/page02** The website is however logically organised in the following form:
                  www.domain.com**/page01/page02** Sometimes the parenting goes to 3 levels: (please help me with the right term here) Domain
                  ↳ Page001
                       ↳ Page002
                            ↳Page003 My question is: should keep the current structure, or is it worth the effort to re-link the website in a parented way. Are there any benefites to one or the other, and could you point to some video tutorials or documentation to read. BqoDAsx.jpg DMMIC5o.jpg

                  Isnt it better to have headlines in H1 and H2 tags instead of p tags?

                  I am working with a simple site http://http://lightsigns.com/Uniko_Manufacturing_Limited.html They seek more SEO traffic. However, the two big headlines that read "Wholesale Supply to the Sign and Display Industries" which is on line 241 and 242 of the source code, its in a p tag, i.e. <p <span class="webkit-html-tag">style</p <span>="padding-top: 0pt; " class="paragraph_style_1">Wholesale Supply to the and <p <span class="webkit-html-tag">style</p <span>="padding-bottom: 0pt; " class="paragraph_style_1">Sign and Display Industries Likewise, the product titles are in p tags, also. For example, on the Slide-in Light Box product page, http://lightsigns.com/Slide_In_light_box.html , I have done keyword research and no one is using the words slide in light box.Plus, it is also a p tag, ie. line 43 reads style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style">Slide-in Light Box If I suggest that they make an H2 tag with SEO-optimized keywords such as Display Light Box - Slide-In LIght Box, would this indeed help SEO? In summary, is it correct to say that H1 and H2 tags are stronger signals to the search bots of what the page is about?

                  Drupal URL Aliases vs 301 Redirects + Do URL Aliases create duplicates?

                  Hi all! I have just begun work on a Drupal site which heavily uses the URL Aliases feature. I fear that it is creating duplicate links. For example:: we have http://www.URL.com/index.php and http://www.URL.com/ In addition we are about to switch a lot of links and want to keep the search engine benefit. Am I right in thinking URL aliases change the URL, while leaving the old URL live and without creating search engine friendly redirects such as 301s? Thanks for any help! Christian
