The most interesting thing about using their services is that they are very knowledgeable regarding all aspects of online advertising for small businesses in general - not just Search Engines! It's hard sometimes coming up with new ideas because some areas can be overwhelming (ie Google Analytics), but I've yet found anything really confusing or lacking there as well. They're also great people who respond quickly when you do have questions or concerns via email/phone calls etc - which helps immensely during launch times especially since everything runs so smoothly once it does start rolling out properly!!
