If you have a URL containing non-Latin characters or Latin characters with accents and diacritics (e.g. "ø", "å", "æ"), you need to use a Punycode translation of your URL when you create ads in Google Ads.
Punycode is a representation of non-standard characters that do not fall within the scope of the encoding system ASCII. You can use a Punycode converter to convert non-standard URLs into Punycode. Using a Punycode URL during the registration with Cobiro is necessary to analyze your website, suggest proper keywords and successfully run your ads. Your real URL will be still working and normally displayed for your website visitors.
