What do you like best?
Quickly identify your client's top search results, the competitors appearing in their top search results, and the imputed values of an organic search term let you show the client the traffic value in dollar terms, makes a powerful business case for client investment in search traffic, you can demonstrate their competitor's ROI, and calculate an ROI for their search marketing with confidence. Also I love the ability to add keywords when they are not currently being indexed by SpyFu, a great feature when your client is in a smaller industry or working with niche search terms.
What do you dislike?
The speed, I wish it was faster and more responsive, the data is fantastic, but it can be a slog when you are trying to build a competitor comparison for a larger website with lots of competitors. I will say the speed has improved dramatically in the past year! Also the client recon industries are probably the biggest markets for search marketing, but I tend to fish in smaller ponds, so the tool is not tuned to help me prospect as much as I'd like.
