Tagging and clustering are awesome, lots of clients have always requested this kind of segmenting. Love the filtering by Striking, emerging, etc. (this is how I like to segment).

Several things, actually, with these 2 being standouts: - pixel tracking - not just rank tracking. This helps you understand why you might be driving less traffic even though your rankings are consistent. (eg it's further down the page than it used to be!) - frequency options - LOTs of options for how often you track a keyword or keyword group, so you can keep a closer eye on volatile rankings while reducing your budget with less frequent tracking on keywords that are less volatile. It's just a great way to take your tracking to the next level, if/when the tool you have today isn't cutting it!
