Why buy a .co domain?

A global domain

Although initially promoted as the country-specific TLD for Colombia, it is indexed by search engines as a global domain extension. This means your website will reach a global audience. It's also the domain of choice for freelancers, companies, and/or corporations, because "co" is associated with business.

Almost a .com

The .co domain is a suitable alternative to a .com and makes a great choice if your .com domain name is unavailable. It might also sound better or be more memorable, which is essential in an ever-growing global marketplace.

The choice of startups

The .co domain is widely used by other entrepreneurs and cutting-edge startups just like yours. Show your customers that you've got bigger aspirations, that you are networked, and raise your visibility with this recognizable domain.

Join the growing and popular .co mmunity

More and more businesses prefer the .co domain extension as an alternative to the .com.

Web addresses that use the popular .com extension are becoming increasingly unavailable. The .co ending is also often (mis-) interpreted as “company,” “community,” “connect,” or “collaborate,” which gives you more room to be creative. The extension can even be set up to respect its original, geographic use as the country-specific domain for Colombia. Some great examples of companies using it for this purpose include tripadvisor.co or jaguar.co. The popular social media platform X also uses t.co as a destination extension for its URL shortening service.

.co domain - FAQ

The .co domain has been classified as a generic country code top-level domain or gccTLD, just like .cc or .io. In contrast, the .com is classified as a generic top-level domain or gTLD. Using a .co domain as a webmaster or website operator will not lead to indexing or ranking problems on Google. Indexing and ranking are determined by things such as content, user-friendliness, page load speed, and other technical requirements.

If you want to improve your ranking on the search engine results page (SERP) in Colombia, you should set your country domain to Colombia in the Google Search Console (GSC). For more informations about this powerful tool, visit our Google Search Console – Things to know before you start article.
