Unsolved Next JS and Missing content

[4thWhale]

Hello
We recently migrated our page to next JS which is supposed to be great for SEO
On almost all our pages we are getting the same errors

Missing Canonical Tag

Missing Title

Missing or Invalid H1

Missing Description

We don't understand this because we have all of that content on every page. We believe that maybe NextJs is having a incompatibility with Moz. Has anyone had any experience with this?

Thanks for your response.

Because we are using Nextjs, it has a built in pre rendering (one of the main draws towards it)

When you mention fallback functionality, can you be more specific about what you mean?

Thanks

Hi

Moz Pro is not a JavaScript capable crawler. So it will be seeing a raw HTML version of these pages.

That said, search engines also have varying and often limited JavaScript capability, and most SEOs would advise you to have decent fallback functionality - perhaps through pre rendering, for example.

You can tell through Google's cache, Search Console, and how you're appearing in SERPs, roughly how Google sees your pages. But keep in mind that Google's handling without any non-JS fallback may be buggy, and other search engines and crawlers (including social networks, for example) will only do worse.
