FAQ

Domain

What matters when choosing a domain?
A domain should be short, memorable, and clearly tied to the brand. The extension depends on the target market, for example a country-specific one for a single market. Risk of confusion and trademark rights should be checked before registration. A keyword in the name, by contrast, brings no reliable ranking advantage.
What needs attention during a domain migration?
Key items are 301 redirects from old to new addresses, adjusted DNS records, a valid SSL certificate, and updated internal links. The change of address should be reported in Google Search Console. The old domain name stays registered so redirects keep working and nobody else takes over the address.
How do a domain, a subdomain, and a URL differ?
The domain is the name, such as example.com. A subdomain is a prefix like blog.example.com that usually designates a separate area. The URL is the complete address of a resource, with protocol, domain, and path. For SEO and operations it matters that search engines often treat subdomains separately.
