The SEO research tool and also the training resources.

SpyFu's overall dashboard is incredible. It breaks down many different important categories all onto one simple screen. They also make it easy to look at different time frames.

One thing that I really like about SpyFu is its ability to show me a detailed analysis of my competitor's SEO strategy. With this information, I can see which keywords they are targeting and where they are ranking, and accordingly I can plan my strategy. SpyFu's keyword research tools are also very useful. They provide accurate data on search volume and competition, which helps me identify the best keywords to target in my SEO and PPC campaigns. One more feature that I appreciate about SpyFu is regarding PPC is that it allows me to see which ads my competitors are running, and how much they are spending on each one. This information helps me create more effective ad campaigns and better allocate my advertising budget.
