You can walk into several large local service companies and find almost $500,000 worth of sales brochures displayed on their walls.
What you cannot do is tell where those brochures came from and what company stands behind them. No two look the same. No two reinforce a common message.
Their inconsistency makes the company look inconsistent and disorganized. A whole set of negative associations follow from that.
If you run ABC's Business Services, you want people to say "Oh, that brochure is from ABC"s Business Services". Word alone will not get that response because our memories are primarily visual. We remember faces but forget names. So show a common face, make that investment worthwhile.
Morale of the story : Repeat yourself visually, too. It makes you look more organized and professional, and easier to remember.
