Duplicate content and no default Next JS redirect from trailing slash

Support
1

I have deployed next.js 11.1.0 test site and noticed that the redirect from trailing slash is not functional.

Both URLs load creating duplicate content and a major SEO issue.

https://cranky-ramanujan-052eb9.netlify.app/templates
https://cranky-ramanujan-052eb9.netlify.app/templates/

Default next.js behavior is to remove trailing slash. For example “/templates/” should redirect to “/templates”.

It tested as expected on localhost and vercel server.

I tried to set trailingSlash: false and used Pretty URLs netlify settings without luck. Please let me know how to make netlify support the default Next.js functionality.

Hi there, @cmsbased :wave:

Welcome to the Netlify Forums! Sorry to hear you are having difficulties, and thanks for sharing some of the steps you have already taken. Would you mind sharing your repo with us, as well as your most recent deploy log? Thanks in advance!

The repo is private so I just deployed strapi corporate starter in public repo:

Same problem replicated via URLs below:

Hi @cmsbased,

Does this give you any insights:

6

Hi. It is not about my target site or SEO. It is all about default Netlify behavior. Vercel and localhost redirect, while netlify loads a duplicate set of content. If I deploy the default next.js starter app, redirect works as expected on Netlify. Not the case with strapi starter. I suspect there is something going on with dynamic routes or third party packages. Either way, you have room for extra improvement of Next.JS compatibility. I would also really appreciate a workaround.

I have just also realized that there are i18n locales defined in Strapi starter, so this could be the first place to look for Netlify incompatibilities .

7

In that case, wouldn’t that indicate something wrong with the configuration or something for that starter?

I’m sorry, I’m not a NextJS expert, so making random guesses here.

8

It works as expected on localhost and vercel servers. It only fails to work properly on Netlify.

Hi there, @cmsbased :wave:

I want to assure you we haven’t forgotten about your questions. I am meeting with members of our team who specialize in Nextjs tomorrow, so I will bring your questions to them so that they can dive in further. Thanks for your patience, and stay tuned!

Hey there, @cmsbased :wave:

Thanks for your patience here while I spoke with the Support team as well as our NextJs experts.

I fully hear how this is an obstacle for you in terms of your SEO. We have an open feature request to improve trailing slash handling, but unfortunately we cannot offer you a workaround at the moment. Should there be movement on the feature request, we will follow up on this thread to update you.

16

hi. it is updated?
It works as expected on localhost and vercel servers.

17

Hey there, @Bilegt :wave:

Unfortunately, I do not have an update for you at this time. Thanks for your patience.

On Vercel trailing slashes are easily removed and the redirection is done automatically
But on Netlify trailing slashes are not removed and any content with both trailing slash or not trailing slash will be considered different by Google.

I suggest using Canonical tags so Google always knows the source of truth

But I have also been able to force all links to have a trailing slash or to not have a trailing slash. Dependent on what you want by using these Netlify Edge Functions
