Signed up and used them for 6 months at 2k a month. They mirror your site so they can monitor clicks and record calls to your site. I found some value in the phone recordings initially but they bug the tar out of you to rate "so they can improve your standing". First problem was I went 4 months without them recording the calls. Sales rep was nice but blamed her techies on the non recording. I managed my own adwords for a year before bringing them on. RL's results were about 10% more costly than mine. I understand they mark up the clicks fairly substantially. One of my issues was putting me on "partner sites". They say the clicks were cheap, less than $. 25 each. Well, that just lowers the overall cost of their clicks for comparative purposes! I finally dumped them after the contract. I still get calls from the rep saying I'm going to be sorry I left them just when their proprietary algorithm was gathering enough data to really help me take off. I think its bull$#*! personally. They will not share their search terms saying its proprietary. So, at the end of the day when you fire them you have nothing to show for it. Your history, your search terms, anything that can help you formulate a new plan is none of your business - even though you paid for it. I'm back to my own adwords account with a person managing it for me for a 20% fee. Better feedback, better results. I just wish I had my $12k back.
