This is an excellent tool; no hesitation to recommend to others.
I would say if you are using it for advertising sales its a great tool. If you own your own business and want to see what the competition is doing it is also a great too. If you did not have a great need for assessing marketing/advertising budgets and campaigns then it would probably be less important.
It would be great if it expanded to Facebook.
I do not make the decision to renew, but if I did I would most likely renew.
The support team at SpyFu works hard and stands by their product. They answer relatively quickly and have always been more than willing to help out when an issue has appeared. With this said, I have only used their customer/product support fleetingly because the platform performs what I need it to do. A lot of the questions that I have had are in help/support pages on the site.
SpyFu is just an overall better package contained in one place. A full comprehensive competitive analysis can be completed with the use SpyFu. In the past, many other competitive tools would be needed, but here, it is all together. SpyFu presents everything in a user-friendly well-organized manner where you can create PDFs to share research compiled with the team, even if they haven't used SpyFu.
This tool has saved us efficiency and guess work regarding content creation. As a small team being able to direct content efforts in the right direction the first time really helps with time restraints.
There has been some loss of time due to needing to filter results and better understand the landscape but those time losses are offset by the smart content creation efficiencies.
The charts that can be exported to give a quick executive level buy-in help move the approval process through quicker and for us to be more nimble with our efforts.
