Update 2015-10-02: Fixed some links.
The BBC have an article and short video interview with an expert from the National Careers Service, about blunders on CVs that ruin you chances of getting the job you want.
The main point is to tailor your CV to each job. One thing that can help is look at the person specification in the job advert.
And you must remember that your CV is like your shop window: just as a shop makes the display of goods in its window as attractive as possible to get customers to come in and buy, you must make the display of your experience, knowledge, skills, abilities and qualities on your CV as attractive as possible to get companies to interview and hire you.
Another piece of advice: you should spend at least 1 hour a week working on your CV.
The National Careers Service has some useful material to help with job hunting which I might post about more in future. (It is a service provided by the British Government for people in Britain, so while you can access the website from any country in the world, don't try making calls from outside the UK to their phone numbers for free advice!) Below is their "about us" page. Why not take a look around at what they offer?
