Generating high quality leads should be a top issue for 100% of marketers not just 59%. Why? If you are constantly looking to support the growth of your business then leads are always going to be paramount. 

From experience there is still a significant disjoint when measuring lead source through to  sale. This is partly because humans are used in the process but more often than not the correct technology isn't being used or understood fully by B2B marketers. 

I appreciate that Kissmetrics is a measurement tool but i dont think they should shy away from hammering home the point, after all without it there is no point!
