International advice.... can anyone help and check my site?

Hi ALL,

I'm running 3 sites, internationally .com, com.au and co.nz

Can anyone please look at my site and give me feedback about the hreflang tags, I ran a W3C and i have errors stating https://validator.nu/?doc=http%3A%2F%2Fzenory.co.nz

for www.zenory.com and its relevant domains

Hi Alex, although I'm starting to doubt myself I'd say the issue is in the values of the hreflang tags. The values are using the ISO codes and I'm pretty sure they're separated with a dash instead of an underscore.

Yes Martijn is spot on.

The format is language-country not language_country.

Thanks Martijn,  I noticed my competitor has the underscore also instead of the dash....

Why would I need to use the x-default?

Thanks Michael!
