Hi Wael,
I don’t quite understand what you mean, could you explain further over email? info@matt-jackson.com

Hello Matt,
I don’t find this code in header.twig. where should I add it.

{% if canonical %}
{{canonical}}
{% endif %}

Best,
D.K.

Hi Anna, I recommend the extension called “Path Manager” be Geekodev, it’s really good for controlling the canonical links in Opencart.

Thank you for your awesome article! Just wondering if there is a way to check if the page is category or product or else then we can have a canonical tag according to that? So I can just put that code into head.tpl file without having to config each custom code for homepage, about page, category pages and product pages?

Hi Bu, in most situations these will canonical back to the main category page.

If not, then you can block the URL variations in the robots.txt if they follow a pattern and don’t conflict with other urls.

Hi Kay,

Thanks for your comment. I said that the {% if canonical %} ..etc code should be in your header.twig already.

The new code should be added to the controller file called “category.php” found at catalog/controller/product, after this line: $this->document->setDescription($category_info[‘meta_description’]);

The new code to add is: if (isset($this->request->get[‘route’])) {
$this->document->addLink($this->config->get(‘config_url’), ‘canonical’);
}

Let me know if that works for you.

Cheers

Thanks for your valuable insights. Using 3.0.3.2 and say your comment about

{% if canonical %}
{{canonical}}
{% endif %}

should be in the header.twig. Are you saying this needs to be added to the header.twig or should this already be in there. If it needs adding, can you confirm where to place in the twig file and here the twig file is located. Thanks so much.

Hi Debbie,

I haven’t tested it with a multistore, but if you’ve implemented it I can check to see if it’s active, just send me an email with the sites – info@matt-jackson.com
