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!

Does Google read dynamic canonical tags?
Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load: <script> //Inject canonical link into page head if (window.location.href.indexOf("/subdirname1") != -1) { canonicalLink = window.location.href.replace("/kapiolani", ""); } if (window.location.href.indexOf("/subdirname2") != -1) { canonicalLink = window.location.href.replace("/straub", ""); } if (window.location.href.indexOf("/subdirname3") != -1) { canonicalLink = window.location.href.replace("/pali-momi", ""); } if (window.location.href.indexOf("/subdirname4") != -1) { canonicalLink = window.location.href.replace("/wilcox", ""); } if (canonicalLink != window.location.href) { var link = document.createElement('link'); link.rel = 'canonical'; link.href = canonicalLink; document.head.appendChild(link); } script>

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!

If you use canonicals do the meta descriptions need to be different?
For example, we have 3 different subsites with the same pages. We will put canonicals so they reference the main pages. Do the meta descriptions have to be different for each of the three pages? How does Google handle meta data when using canonicals?

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!

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.

Header Tags
Ok so I am writing different pages and the first heading is an H3 just because I wanted to it be a certain size. Then as you see the content, I have an H1 tag. Example page: http://www.oxfordmshomes.net/condos/acadia-court-Oxford-MS you can see that "Acadia First" is the first thing you see on the page and it uses an H3 element. Long story short, my hierarchy is wrong. Does this have any negative effect on my SEO efforts?
