The best kind of marketing is the kind that gives at the same time it wants to get something. The Bing Search engine has an ingenious marketing idea; each day for the month of December a visitor can obtain a gift per day. Some gifts are ads for products, but sprinkled among the products are freebies---patterns for holiday decorations, holiday music and video, special deals from vendors.
And these are the types of things that bring customers back to you over and over again. I may not have frequented Bing's search engine much over the previous month, but just about every day since I got my December email I've been going back to the site to see what's next.
It's fun. It's inspirational.
