If you want to be successful with Internet Marketing then you need to begin with the end in mind. Far too often would be marketers have a 'build it and they will come' attitude. Sadly, many times 'they' don't come and those 'would be's' end up being forever 'wannabe's'. Let's not make the same mistake.
That is why any Internet Marketing campaign should begin with proper market
research. The good news is that there are plenty of tools available.
I would also recommend when purchasing a new domain it helps to have your target keyword as part of the domain name {HINT}.
Just for your information, these are the average fees paid PER CLICK by the top advertisers for the following keywords:
Cheap flight $ 4.00
Credit Card $ 15.45
Holiday $ 15.53
Mobile ring tone $ 5.15
Smoked fish $ 0.20
Vegetable delivery $ 0.05

So, it is important to know the value of your market before you commence investing a huge amount of time and effort. A broad rule of thumb is the more lucrative the market, the more time and effort you will need to invest to dominate that market. If you're getting started, much better to find a tiny niche to cut your teeth on. Sure, the rewards wont be as big, but at least you should achive a modicum of success, which will hopefully drive you onward and upward.
There are many sites where you can find the top paying keywords but I suggest you use the free traffic estimator in Google Adwords as a good starting point.
One other important point:
When a surfer uses 1 to 2 words they are generally just doing research i.e. digital camera. When they use 2, 3 or more words the surfer is generally looking to buy something as they are further down the buying 'path' i.e. Nikon digital camera. If they type in the actual product name i.e.Nikon D80 Digital SLR Camera then they ARE READY TO BUY and are usually completing the last stage of price and value comparisons amongst the various sites.
So ideally, you should be looking for business segments that you can wrap up in two or three words i.e.
vintage engagement rings
Note and one big long word of caution,

because this will get ridiculous when you start to add sub-domains
