Using Keyword Difficulty Report along with OSE to calculate SEO Pricing?

[easystreetint]

Has anyone thought of or created a algorithm or Excel function that uses the results from the Keyword Difficulty Report percentage of difficulty and SERP ranking analysis set against potential client's own OSE rankings to come  up with an estimated SEO pricing tool?

I might use the keyword difficulty tool to determine which jobs I would not want to accept  -  due to lack of time and staff - to attack a brutal, maybe impossible target.

I might also use it to get some idea of how difficult a job might be.

However, the best data that you might have is a chart that compares keyword difficulty of your previous clients, their relative starting point in the SERPs and the amount of money that was required to produce whatever result was achieved.

Then a variable that only you can answer is your relative effectiveness in different niches.  If I was given the job of competition for "hydraulic jacks" I might know exactly how to approach that and have industry knowledge, quick resources and allies at hand - these will enable me to jump right up the SERPs.  However, if I get the job of attacking "easy chairs" I might be really challenged because I don't have the same level of knowledge and support - plus the competitive landscape will be very different.
