To turn one sale into three you could tell your customer if they refer four friends to your web site, and if friends buy from you, they will receive a full rebate of their purchase price, therefore turning one sale into three.

When you sell a product, give your customers option of joining an affiliate program so they can make commissions of their own selling your products. Their belief in product is unshakeable because they bought it! It is far easier for anyone to sell something they believe in than someone selling ‘cold.’

After making your first sale, follow-up with customer. It makes sense to follow-up with a "thank you" email which includes an advertisement for another product you sell. Backend marketing is blue print to your business’s success. It costs dearly to harness each customer but following up with further offers is completely free, so why not follow-up every few months?

In international bestseller "Blink," Malcolm Gladwell explains why our decisions to choose brands, select a mate, sue our doctor or make choices that decide Presidential elections, aren't as simple as they seem.

Why we often let unconscious biases affect our opinions about people who are taller or have a different skin colour. And why we find it even harder to explain them when asked.

I consider "Blink" essential reading for all marketers. I mean, which blue-blooded marketer wouldn't love to know how workings of their customer’s brain will decide if their new packaging is going to work or fail?

Or why their new website is converting far fewer visitors than old one? Of course we would.

But is it really possible to understand why people choose Budweiser over Coors? George W. over John Kerry? Coke over Pepsi?

No one knows for sure. And asking people why they took those decisions doesn't necessarily give right answers.

Why? Because most of us really haven't a clue as to why we make those choices.

95% of consumer decision-making occurs subconsciously, according to research from Harvard University, cited in an article in Time. That's a hell of a lot of decisions we have little or no conscious control over. http://www.time.com/time/insidebiz/article/0,9171,1101040308-596161,00.html&e=9707

In Blink, Gladwell also shows how sometimes sort of data that marketers rely on - such as market research and focus groups - can fail miserably because they don't always predict actual consumer behaviour, as Coca-Cola discovered during New Coke fiasco.

But new research is beginning to shine a light on mysterious workings of neural processes behind those snap decisions.
