I need help with a PHP canonical URL tags
-
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

Dynamic Canonical Tag for Search Results Filtering Page
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!

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?

Quick Fix to "Duplicate page without canonical tag"?
When we pull up Google Search Console, in the Index Coverage section, under the category of Excluded, there is a sub-category called ‘Duplicate page without canonical tag’. The majority of the 665 pages in that section are from a test environment. If we were to include in the robots.txt file, a wildcard to cover every URL that started with the particular root URL ("www.domain.com/host/"), could we eliminate the majority of these errors? That solution is not one of the 5 or 6 recommended solutions that the Google Search Console Help section text suggests. It seems like a simple effective solution. Are we missing something?

How long does it take for canonical tags to work
How long on average does it take for a canonical tag to work? Understand that canonicals are just a suggestion, but after adding a canonical tag and submitting the page via Google fetch, assuming Google follows the canonical, would you expect it to work after a day or two or does it take longer? We added canonicals to old PPC landing pages that are ranking organically, though our new landing pages (which we want to rank organically) are not identical and have a bit more content/features. They are similar though. Canonicals were added to the old pages (pointing to new pages) and requested indexing via search console. Old pages are still ranking and new pages not so much. FYI we are unable to 301 old PPC pages due to other non negotiable reasons unfortunately. Thanks.

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

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?
