You covered all the bases when coming up with a domain name, entered your preferred option into the IONOS domain check, and the result was that the URL is already taken?
No need to worry, we're here to help you find a domain! On the same results page that informs you of the availability of your preferred URL, we will also show you numerous alternatives or recommendations that fit your original choice. There are now numerous top level domains which you can use. For example, if .com is already taken, why not try .co, or one of the many other new domain endings. You can find domain endings for specific fields, like .restaurant for gastronomy websites, or .tech for technology companies. In any case, you're certain to find a suitable domain name for your online project.
Alternatively, you can always make a slight change to the spelling of your preferred web address - like using a hyphen to break up words, or even changing the order of words in your URL. That way, for example, handymansmith.com can easily become smith-handyman-business.com. Be creative and allow yourself to compromise on your original choice when finding a domain name.
