Google Best Practices for URL Structure of AMP Pages

Google’s John Mueller recently explained the do’s and don’ts of choosing a URL structure for AMP pages.

This was explained during a Google Webmaster Central hangout held on April 9.

Mueller answered the question of whether Google prefers a certain type of URL structure when it comes to AMP pages.

Here is the question that was submitted by a site owner:

“I was wondering if there is a best practice for URL structure of AMP pages. If you use subdomain or top level folder, you can have better parsing possibility in different tools.

But I was wondering if there is any benefit to Google if you place your AMP pages under the root domain instead of a subdomain or settings.

Muller’s response

Mueller talks about the URL structure of AMP pages

Mueller said the only thing Google is concerned about is that AMP page URLs are all on the same domain.

As long as the AMP URLs are all on the same domain, how you choose to structure them is acceptable to Google.

“From Google’s perspective, I think the only critical criteria for AMP pages is that they must belong to the same domain.

So if you have it in the subdomain, or a subdirectory, that’s all perfectly fine.

If that’s all that matters to Google, then what should site owners choose?

Mueller’s advice to site owners is to go with the URL structure that best suits your current setup.

This means that the structure of the URL must be:

  • Easy to follow
  • Easy to monitor
  • Easy to maintain
  • Compatible with your CMS
  • Compatible with your server.

“In general, with these types of related pages, I would recommend doing them in a way that works best for you. So something where it’s easy for you to follow, it’s easy for you to monitor, it’s easy for you have to maintain this configuration, so if it works well for your CMS, for example, or if it works well for your server configuration, it’s a good choice.

If you’re looking for a specific optimization technique for AMP URLs, you might be out of luck.

Mueller says nothing makes a big difference when it comes to AMP URLs.

“I wouldn’t worry if there’s any adjustment from Google that makes a big difference when it comes to these alternate URLs.”

There is one thing site owners need to be aware of, but it is something that applies to all URLs.

Be careful not to change your URL structure too often.

Ideally, you should choose one and keep it for as long as possible.

If the structure is changed, Google must reprocess all URLs, which can negatively impact rankings.

“The other thing I would be careful with these alternate URLs is that you don’t change the templates too often.

So ideally, if you choose something like a subdirectory or subdomain, try to stick with it for as long as you can.

It’s not quite the same as changing your primary URLs as far as search goes, but anytime you change URLs in general, we have to kind of reprocess that.

If you change the alternative URLs associated with each page of your site, it means that we have to process a large number of URLs to understand this new configuration.

So choose subdomain, subdirectory or settings if you want. Whatever suits you best. And try to keep this configuration, ideally, for the long term.
