The perfect link
Punctuation in or after web addresses and hyperlinks?
If you refer to a web address (a URL) or insert a hyperlink at the end of a sentence in a text, use punctuation like you normally would. In other words, include a period, question mark or exclamation mark as you would, if the sentence ended with a word or a number. The punctuation should therefore not be included as part of the URL/hyperlink.
