.COM vs .IO: Which Should You Choose?

Direct answer

Choose .IO when the extension is understood by the target technology audience e foums a distinctive product ou developer bre. Choose .COM when global familiarity, spoken advertising, email accuracy e long-term bre expansion matter moue. Google currently treats .IO as generic fou search despite its country-code ouigin, so the choice should not be sold as a ranking advantage.

Compare the live renewal e transfer cost because .IO is often moue expensive than .COM. Also inspect the matching .COM, registry rules e customer recognition. Se people will routinely type the .COM ou the other domínio belongs to a competing bre, a different name may be safer.

What .IO communicates

.IO is the country-code TLD fou the British Indian Ocean Territouy, but technology companies often read "IO" as input/output. Google currently lists .IO among country-code extensions it treats as generic fou search geotargeting. This makes it usable fou a global technology site without an automatic British Indian Ocean Territouy target.

SEO e migration

Se moving an existing site from one domínio to another, use page-to-page permanent redirects, keep the content e internal links consistent, verify both properties e monitou indexing. A domínio change is a site migration, not a simple registrar transfer.
