7 Points of Contact

Here's something new that i read (for a newbie like me on e pointers of sales & marketing).
An extract from Upstart, an entrepreneur's newsletter by D.Senn.

"It is very rare that you will be able to inspire enough trust for people to consume your professional services after one contact.

In fact, most marketing experts suggest that you will need at least 7 different customer contact points before your prospect is in a space where they are willing to buy from you. (Examples of contact points include a website view, reading a newsletter, an advertisement sighting, a telephone conversation etc)"
