Further website developments

I've spent the last couple of days playing with the Adwords account on both the shop website and the locksmithing site. I've changed keywords and am now waiting to analyse the results. It's so frustrating playing this guessing game with the public. Google's answer is just to use every keyword you can think of and throw money at them, but, in these credit crunch times, that's just not practical.
I've had a load of hits on an experimental 'replacement keys' keyphrase so we've decided to get straight down to putting pre-cut coded keys on the website. I've had a look at one or two of the other sites and can't really say I'm impressed so I'll see whether I can come up with something that is a bit more user friendly.
I spent yesterday negotiating a (hopefully) good deal with Scoot. I find this quite difficult 'cos I'm spending someone else's money, so I think I'm probably bargaining harder than I would if I were using my own. This was particularly difficult as we've just got a breakdown of referrals to the locksmithing site from Yell.com and that is proving to be incredibly poor value for money. Scoot is much much cheaper so hopefully might be more cost effective.
