Hello,
We do have a client with a site in multiple versions (one domain per country). French and Spanish versions work really fine, but the problem comes up with the .com and .co.uk versions.
This is my hreflang piece of code:
When I go to Google.co.uk and search the exact match domain keyword "how much cost an app", I only find the howmuchcostanapp.com domain (1st or 2nd page) instead of howmuchcostanapp.co.uk. The UK one is not appearing! This is very strange. I have spent a lot of time trying to solve this, but I don't know what else to do.
Thanks a lot in advance for your comments and help!
