Because most scoring frameworks need numbers nobody has. Somebody invents an impact score out of ten, the total looks rigorous, and the ordering is really the inventor's opinion with arithmetic on top.
The priority matrix plots opportunities by plausible value against estimated effort.
Value comes from the affected page's actual impressions, click curve and any revenue it has influenced. Effort comes from fix type and your own completed items. Neither is invented.
A quarter's work is chosen from the top-left of the matrix — high plausible value, low effort — and the reasoning is visible to everyone who has to live with it.
It will not decide for you. Something in the high-effort, high-value corner may be exactly right; the matrix informs the conversation rather than replacing it.
Page value from real performance, effort from historical completion, and the backlog it orders.
Your own click curve and revenue, not an industry model.
Yes, and manual estimates improve the model.
Per property, and it can be filtered by section or owner.
Fourteen days, every module, no card. Or half an hour with someone who will run it on your own records and tell you where it does not help.
