Links are great. They signpost people to related content and add additional context and depth. Embed links in the natural flow of the content; never use "click here" or "read this" for a link – it's not in the least bit useful. Unspecific and non-descriptive link text like this is especially unhelpful if you're using a screenreader.
A good link tells you what to expect if you click on it. A well-integrated link could be changed to plain text and the sentence would still make sense:
If you're writing for print and need to spell out the URL, write it all in lower case, and don't include the "www" – it's pretty redundant nowadays.
There's also no need for the "https://". It's increasingly standard and it's an extra hassle for people to type it in after reading it in print. Plus, they'll be able to see the padlock sign in the address bar once they're on the relevant page if they're worried about security:
In print, highlight the URL in bold, and punctuate the sentence as normal.
Write email addresses in lower case, with normal punctuation. In web content, make email addresses mailto: links. In print, make them bold:
Never write “E:” followed by an email address – the format it's in makes it obvious that it's an email.
There's no need to put a hyphen in "email". That's a 90s thing that would make us look behind the times.
