I have a national website and an international website. The international website covers the rest of the world so not country specific. This website is based on a subdomain of my national site
When I type the brand in my national Google the international site homepage ranks higher than the national homepage. The international site homepage has a higher Page Authority in Moz so my thoughts to make the national site rank higher goes towards regional relevance link building and geo targeting in the Search Console.
Link building is a long game however and I was wondering if there is something more technical I could do to increase these chances?
