Securing various domain extensions or common misspellings of your primary domain as aliases can help you prevent others from using similar domains to potentially divert traffic or harm your reputation.
Domain aliases make it convenient for users to access your website using different variations of your domain name. This ensures that visitors can reach your site even if they mistype the domain.
Domain aliases are useful for creating specific URLs for marketing campaigns, promotions, or events. This allows you to track the effectiveness of different campaigns.
For businesses operating in multiple countries, domain aliases can be used to create country-specific versions of a website.
