Cross Domain Canonical (Technical SEO)

[rblindwein2024]

Hello everyone,

I've been researching for a while now, but I'm getting nowhere. I hope someone can help me.

The initial situation: We have 3 online shops.

Online shop 1: 90,000 products --> By far the most SEO power

Online shop 2: 60,000 products

Online shop 3: 40,000 products

Problem:

- Products from online shop 2 are listed in 1

- Products from online shop 3 are listed in 2 and 1

Product listings are almost identical, so we have the problem of duplicate content. At the moment, each product refers to itself.

We would like to set a different focus for each online shop. Creating unique content is not possible.

I would like to implement cross domain canonical tags to signal to Google which is the canonical URL.

Now to my question. Where in Adobe Commerce can this be done?

I can only find the setting options: https://experienceleague.adobe.com/docs/commerce-admin/marketing/seo/meta-data.html#canonical-meta-t... 

"Use the canonical link meta tag for products"

"Use the canonical link meta tag for category"

However, I would like to decide for myself where the canonical tag is referenced.

What options are there here in Adobe Commerce / AEM Sites?

Best regards Robin

There is no out-of-the-box solution for your specific needs that you can just configure in administration.

What you're asking for requires some custom programming, but nithing an experienced agency couldn't deliver relatively easily.

Hi,

If the only similar pages are the product pages this is no big deal.

The duplicate content is not really punished by Google when it on product pages.

There are a lot of products that are sold on different websites and have the exact same product description.

Maybe you can organize your categories differently and change your product titles and H1 in each website. A big part of the job can be done automatically.

If you set up a cross domain canonical the only thing it will do is that you will lose your SEO trafic on websites 2 and 3.

It sounds like you're dealing with cross-domain canonical issues, which can be tricky when you're managing multiple shops with overlapping product listings. To make sure your SEO efforts aren’t being diluted, you’ll want to establish clear canonical URLs for each product, ensuring that search engines recognize the correct source for each one. In case you want to simplify managing this at scale, tools like CrawlSpider can help automate the identification and proper tagging of cross-domain URLs.
