Dynamically returning the cell position of a field in a pivot

Hi,

I have a pivot with data about search rankings.
The data consists of keywords matching webpages for many given positions.

Objectives: to build a formula that retrieves the rank of each keyword on a per webpage basis such as this one:
=(GETPIVOTDATA(TEXT("Rank",),$A$1,"Product","Internet","Webpage",$A$5,"Keyword",$A5))

Constraint:the formula needs to be pasted into a very long column alongside the companion pivot table without any modification.

The Catch: some keywords are associated with more than one webpage. Therefore, the hardcoded "Webpage" cell position ($A$5) in the formula above has to be modified as often as there are webpages in the pivot table...

Goal: to replace any hardcoded reference to the "Webpage" ($A$5 in the formula above)
by something dynamic (address, match, find ???) which would
- look for the closest cell above with a string containing "http://",
- return its position and
- feed it to the getpivotdata formula

I have included a spreadsheet to illustrate the situation.

Thanks for the time you take to review this request for help

*** Edited ***

LOOKUP approach, put this in cell D5 and copy down:
[D2]=IFERROR(GETPIVOTDATA(TEXT($B$4,),$A$1,"Product",$B$2,"Webpage",LOOKUP(2,1/(LEFT($A$5:$A5,4)="http"),$A$5:A5),"Keyword",$A5),"")


The LOOKUP function finds the last row in column A starting with "http" and has built-in array functionality so CTRL-SHIFT-ENTER is not required so should be more efficient than those type of array functions deriving the same result (tho, I may stand corrected!)

For more on the LOOKUP function and how it works in this instance, see this tip:

Hello Dave,

I accept your solution for my situation.
 
More important, you just teached me a neat trick with the (2,1/(A:A<>""),A:A) part, very informative with the linked explanations.

Thanks a lot, much appreciated.

Note: yesternight, I worked on it and came up with a cumbersome solution that provided me with the cell position:

=IF(ISERROR(CELL("address",INDEX(a:a,MATCH(VLOOKUP(a28,URL,1,FALSE),a:a,0)))),OFFSET(b27,0,0),(CELL("address",INDEX(a:a,MATCH(VLOOKUP(a28,URL,1,FALSE),a:a,0)))))

Benching against a named range listing all the URLs and upon an error, I was able to retrieve the position of the above cell containing the url then feed it back into the getpivotdata formula to extract the rank...

The provided solution is simple yet effective.

However, the most valuable takeaway from Dave resides in the linked information from a previous contribution he made that explains how the Lookup(2,1/(A:A<>""),A:A) works.

See: http://www.experts-exchange.com/Programming/Languages/Visual_Basic/Q_27669653.html#a37829864

I learned something important here.
Thanks Dave for your comprehensive solution.
