Being short: Having one domain per state (country's states. Brazil in this case) on the same ccTLD and redirecting users to the localized website, all of them possibly but not necessarily linking back to the parent site, is good for SEO? Or can this impact negatively?
The website already has different content for each state, it's just a possible course of action to get other states to rank better, since most search is done for specific states. We have a lot of reach on a couple states, but we want to get other states to rank better, and having them on the domain and website name looked like a really good idea.
