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

Trailing slash URLs and canonical links
Hi, I've seen a fair amount of topics speaking about the difference between domain names ending with or without trailing slashes, the impact on crawlers and how it behaves with canonical links.
Technical SEO | | GhillC
However, it sticks to domain names only.
What about subfolders and pages then? How does it behaves with those? Say I've a site structured like this:
https://www.domain.com
https://www.domain.com/page1 And for each of my pages, I've an automatic canonical link ending with a slash.
Eg. rel="canonical" href="https://www.domain.com/page1/" /> for the above page. SEM Rush flags this as a canonical error. But is it exactly?
Are all my canonical links wrong because of that slash? And as subsidiary question, both domain.com/page1 and domain.com/page1/ are accessible. Is it this a mistake or it doesn't make any difference (I've read that those are considered different pages)? Thanks!

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?

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>

Canonical Tag when using Ajax and PhantomJS
Hello, We have a site that is built using an AJAX application. We include the meta fragment tag in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

Changing title tags, do we need 301 redirects
I found many duplicate title tags and I'm in the process of changing it Do I need 301 redirects in place when I switch it? I am only changing the title tag. Also, we are switching over to a new site very soon, I am worried that we might be using too many 301 redirect "hops" because we are doing a lot of optimization as well. (video from matt cutts describing 301 redirects and hops: http://www.youtube.com/watch?v=r1lVPrYoBkA. Does anyone have any experience in doing too many redirect hops that it affected your rankings? Any good ideas to avoid this?

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

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 ?
