Google Analytics : 2 different periods

Hi again,

I need to compare data from Google Analytics between 2 different periods, for example "sessions" from this week versus last week.

How can I do this in "Formula" ? Is there any syntaxe to write it ?

Hope you can help me, I thank you for your replies.

Why not create two formulas, one for each period?

Hi again,

I want to compare 2 different periods to calculate the variation (+10% CTR, + $1.50 CPC, etc).
Maybe do you have a better way to obtain this result ?

Thank you Niels.

That should be pretty simple to build using Excel formulas?

If I have time someday I'll write a pretty blog post about it.
