When using the Social Media Networks to promote your book, you need a custom banner that is eye catching. Banners are almost as important as your book cover for attracting potential buyers. On an average, you have about 3 seconds to get the attention of someone browsing the Internet, so you need to be able to immediately grab his or her interest long enough to hold them there. Empire Publishing has in-house graphic designers with over 30 years experience. Each social media network requires a different size banner. We send you the correct sizes for Facebook, Twitter, Tumblr, and Google+.
