Michel, yeah i found it, it had gone to my junk mail for some reason.
It looks like you have it set up right to me, i would lower the daily spend though coz if somebody in your area objects to your new advertising campaign and keep clicking on you, you could be a couple of hundred quid down in no time.
Your add shows if i type in carpet fitter west london
so the only thing i can think is nobodys searching in west london
in my experience people will either search more broadley ie "London"
Or they will narrow it down ie, "Kilburn" "Islington" "Hamersmith"
just add these to your keywords
Try this and it should work
