Canonical Tags for Pagination on PLP

[sja-dS]

• FACT-Finder-Web-Components Magento2-Module version (see composer.json):
  • 1.6.8 (with FF NG v1.1.3)
• Magento edition and version:
  • 2.4 B2B
• PHP version:
  • 7.4
• Expected behavior:
  • On a Product List Page the Canonical Meta Tag in the Header should always reference to the current Page
• Actual behavior:
  When you are on a page, e.g. https://www.myagrar.de/pflanzenschutzmittel/?page=2 the canonical Reference is <link rel="canonical" href="https://www.myagrar.de/pflanzenschutzmittel/"> but in this case it should reference to https://www.myagrar.de/pflanzenschutzmittel/?page=2
• Steps to reproduce:
  • Open above Links and look the Codecode

Hi @sja-dS
The issue has been already queued an we will look for possible solutions, i guess modyfing the page parameter in href with new number will be sufficient.

hi @sja-dS Is page parameter the only one we should take into account? What about different parameters that also manipulates the content of the page like sorting or filtering?

Hey @a-laurowski
I sent the question to our Customer, what would the best for him and send you the answer as soon as I get them.

Hey @a-laurowski
I got some Feedback from our Marketing Department.
The page Parameter would be sufficent.

hi @sja-dS

Please check the following PR if its suitable for you #338

My concern is that according to an article https://www.searchenginejournal.com/technical-seo/url-parameter-handling/#close any parameter which changes page content should be contained in the canonical link. I think this is something we need to discuss internally.

The goal of the module is always to provide the best flexibility and perhaps we should consider a mechanism which allows user to at least select which kind of parameters (paging, sort order, filters) should be applied in the canonical link

@a-laurowski
PR looks fine to me
A config which parameters should be used would be perfect.
I'm not a SEO Expert so i don't know what would be best Solution. So the Config would be the best and flexible Option, I think

hi @sja-dS
With current amount of work in other areas than Magento2 module i'm afraid i can't tell the exact date. I think the end of September is a realistic scenario of next release but things may have changed.

For the time being, if you need this functionality, please add it to one of yours template. It could be placed anywhere in the DOM (after.body.start block in my opinion is good place), the most important thing is that it has to be wrapped inside the ffReady event listener if you want to be sure a given callback is successfully registered.

Hi @sja-dS

We have some new thoughts on this problem.
First we need to take into consideration that when you interact with the product listing all actions done by Web Components are asynchronous.

We think that the only case to cover is to provide correct link only on initial rendering of the page, further asynchronous actions like changing page or filtering are irrelevant.

As a proof of this way of intuition you can check the page source. It looks that dynamical changes on the canonical link are not contained there and page source is more or less this what web crawlers will see during their visit.
So from our point of view it is important for this link to be formed yet on the server side. And because dynamical changes does not impact the page source and because the web crawlers will not perform any asynchronous filtering, page changing or anything like that, a dynamical changes on the canonical link is pointless
