I was wondering if there are advertising industry standards on displaying website URLs in print ads? (for brick & mortar company having a website).
Definitely not http://
If you omit (the redundant) www you can increase the text size of the URL in your ad.
I have seen some less tech-savvy folks not understand that www. is optional, and couldn’t find a URL in an advertisement.
So it depends on who you’re targeting – tech savvy or not. If you’re not sure, put in the www.
