Hoping you can help me out with some best practice here. I run an Aussie based job board called the Backpacker Job Board. The site ranks really well and has plenty of traffic.
I want to launch a New Zealand version of the site. I've got a stripped down version of the site at the following URL. It has the same categories - but different content. (currently blocked by robots.txt while I develop).
Is it possible that launching this NZ site will cause problems for the rankings of my .com.au? The site structure and code is pretty much the same.
Furthermore, noting that the job listings will be unique to each site but the categories would be the same, would it be worthwhile using the rel alternative tag on category pages? Is this more for languages rather than for geotargeting?
<link rel="alternate" hreflang="en-au" href="http://www.example.com.au/jobs/fruit-picking-jobs/" /> <link rel="alternate" hreflang="en-nz" href="http://www.example.co.nz/jobs/fruit-picking-jobs/" />
These aren't exactly translations of each page rather their own distinct category. ie. One is for fruit picking jobs in Australia and the other for Fruit picking jobs in New Zealand.
