If you sell houses then the chances of you getting to the top of Google for the keyword "houses" are going to be slim, to say the least. If you are working in an extremely competitive market, then you need to look outside of the box and start looking at easier keywords that you can rank for, because realistically, it is going to take a lot of time, effort and a little bit of luck to top the charts for the most competitive search terms.

Many people think that they should always go for the most popular keywords, but these often tend to be the most competitive, so you need to look at the long tail keywords. If you targeted 5 long tail keywords that all attracted 200 searches a month but were less competitive than one that attracted 1000 searches a month, you stand more chance of getting the traffic you want in a much shorter time.
