How to search for a testing job in london

Hi Guys ,

I am new to London and i have software testing experience but the problem I am facing here is, I am not sure how to start looking for a job . I have been applying  in jobserve for quite a while now but have not yet got any interview job . My friends here suggested me not to register in any job search website as our CV would be registered with them . I am so confused about this and not sure what to do . Can anyone help me with this ?
