SpyFu displays side-by-side data on your competitors' paid and organic search results, so you can easily see where it's more cost-effective to bid on a particular keyword as opposed to trying to rank for  it organically. That way you can use your time more efficiently by writing content around those keywords that drive a lot of traffic but are more expensive to bid on.
