问题
I have many links on my site that have query strings that contain %26 (which is a URL-encoded ampersand). For example:
?action=keyword_results&f=company&q=Bausch+%26+Lomb+Canada+Inc.
Apparently, Google Analytics is prematurely decoding the query string and it treats the text after the %26 as a separate parameter.
I use the Exclude URL Query Parameters option to exclude most query parameters (including action, f, and q) from our results. But I am getting stats for hundreds of pages with query strings like ?+Lomb+Canada+Inc. and I can't exclude them because they are all different.
I've tried a variety of Google searches to see if this is a known bug. But all I found was people having trouble because they weren't encoding the ampersand.
Am I doing something wrong? Is this a bug? Is there anything I can do to clean up my reports?
回答1:
You could try creating a "search and replace" filter on Request URI and use regex to replace '%26' with '&'. Unfortunately, I'm not too experienced with regex, so I can't really help you there; you might have to ask someone else to write one for you (or figure it out yourself, of course).

edit: I think it could something as easy as: search string for: %26 replace it with: &

But just create a separate profile and test it, I guess.
