% of clicks from % of keywords

[shorebreak]

Hi all,

I'm trying to get a sense of what % of click-throughs or transactions typically come from what % of your total keyword lists.

I see keyword portfolios where 95% of transactions come from the top 5 (out of 2000) keywords, others where 80% of transactions come from the top 10%, and then some programs where the spread is much more even.

Anyone care to share anecdotes?
