.io
The .io domain extension is an Internet country code top-level domain (ccTLD) assigned to the British Indian Ocean Territory. However, it has grown popular among information technology industries as "IO" is a commonly used abbreviation for input/output in computing. Additionally, the .io extension has gained popularity among startup companies due to the availability of desired names compared to the saturated .com domain. Despite its higher cost than other domains, firms often choose .io due to its tech-savvy and modern connotations. It also benefits from search engine optimisation, especially on tech-focused searches.
