General guidance, to be adapted to your case.
In Cantù we work with companies between Milan and Lugano and set up domains and multilingual websites consistently. For the rules on registering a .ch, always check the official sources.
Registering multiple extensions of the same domain is worthwhile to protect your brand name or cover more markets, but only the ones that are really useful. For a company in Como or Brianza with customers in Ticino, it can make sense to pair the .ch with the .it.
The domain name affects SEO only indirectly: it helps recognition and trust, but content and the technical quality of the website weigh more. From Cantù we help companies in Como and Milan combine domain, website and SEO content.
If the domain you want is already taken, you can try a variant of the name, another extension, or check whether the domain can be transferred, without infringing anyone else's trademark. From Cantù we help companies in Como and Brianza find the alternative most consistent with the brand.
To transfer a domain to another provider, you request the authorisation code from your current supplier, enter it with the new one and confirm the move, after checking the owner, the domain lock and the DNS records. In Cantù we handle the whole procedure for companies in Como and Brianza.
An email address on your company domain makes you more credible and recognisable, stays the property of the company even when people change and can be protected with anti-virus and anti-spam. For businesses in Como and Brianza it is often the first contact with customers, so it is part of the image.
