If you've arrived here looking for a domain parking definition, i will try to be as short as possible but i will concentrate on how to make money with parking.
Domain parking it's a service that some Parking companies (sedo, name drive and others) offer where you point your domain to them, tell what is your domain about (music, sports, etc), and they automatically build a site (with little or no content) with paid ads.
When someone clicks the ads, you make money.
That's all.
Sounds easy? It is! You don't have to design a site, prepare content, no hosting bills to pay, no nothing! This is a paradise for the lazy domainer.
Now...
will you make money with this? This is a good point and the answer is easy.
There are guys making big money with parking...
and guys earning nothing from it.
Why? Since Parked Domains have no content, It's not easy to drive traffic for them and you have to use some special techniques to get more traffic (fortunately they work pretty fine!).
At this moment you might be asking...
How do they do?How do the big domainers make money with parking? Answer it's easy: They are even more lazy than you.
They get (register) domains that get traffic from the minute zero.
They get expired domains (that still receive traffic), misspelled domains (also called typo domains) that receive big traffic and more! See? Everything it's reduced to domain registration.
This is how the big domainers make money with parking.
