Ive been a customer for 3 years and every year Metric Theory keeps improving the ROI on our account generating impressive growth in our online demand. Ive had 15 years of managing a PPC account. Ive done it myself. Ive hired consultants. By far Metric Theory has been the best option in keeping up with this rapidly changing environment and maintaining costs at a reasonable levels. Highly recommended!
Our experience with Metric Theory was mixed. They did a great job making our adwords more specific and thus lower costs per click but set up many campaigns with the wrong landing pages, ad copy and limited keywords that all had to be redone. This has caused months of extra work for us. Unfortunately, we do not recommend them.
