It just does not make any sense to put an icon for Facebook or Twitter in print ad without giving your URLs or official page titles for readers to find you quickly. I saw this big ad in TOI today with one of the call for actions being “Follow us on Twitter and Facebook”, despite the space being available to mention the URLs or official handles, there was just no mention of the same. To add to that the name is common enough to generate enough pages if you go ahead and search for it.
I recently observed even a television commercial doing the same – a prominent chocolate company ad on television stated “participate in our contest on Facebook and win prizes”, well the screen with this message lasts for few seconds, but all it mentions about the location to participate in contest is a plain “F” icon for Facebook. No mention of the page URL at all. And if you go ahead and search for that brand on Facebook, there are enough pages with that brand name to get you confused about the identity of the official page.
Please remember it’s not a web or interactive digital ad in front of your customers where they can click the icons and land up on your page. Won’t harm (esp. when you have space to utilize) to mention something like @yourname or /yourname near those icons. Easier for your customers to reach the right location quicker!
