How to promote yourself?

Viral marketing is a marketing phenomenon that facilitates and encourages people to pass along a marketing message voluntarily.[2] Viral promotions may take the form of funny video clips, interactive Flash games, advergames, images, or even text messages.
It is claimed that a satisfied customer tells an average of three people about a product or service he/she likes, and eleven people about a product or service which he/she did not like.[3] Viral marketing is based on this natural human behaviour.
This is a great, low-cost way to spread an idea, your name, your brand because if you have the right ingredients your idea can take off and spread like wild fire…without you even breaking a sweat.
One of the most popular campaigns we picked was created on a $1000 budget. A few others were created by in-house shops or single-man operations. That’s not to say you shouldn’t hire an experienced viral agency to help (many of the best are represented here too.) But, if you can’t afford it and you are a *very* clever and/or lucky marketer, viral can still be do-it-yourself tactic.
Now…for that list. Real estate agents of all stripes–prepare to be inspired!
1. Known as “Real Estate’s Greatest Sales Legend,” the slimy Ted Truit and his interactive website (quiz and all!) created a firestorm of response from Virginia REALTORS, and birthed an effective image campaign for VAR.

So try to demonstrate why you are totally different from your competition. One way is to use your business card placing as many testimonials from previous clients as possible on the other side.
