Many of the query parameters used in your URLs may not be relevant for analytics. For instance, an “orderid” parameter in your confirmation page URL may be needed from a Website programming standpoint, but it would probably be most useful to strip “orderid” out of the URL for consolidation in the Pages report and elsewhere in Google Analytics.
Does the query parameter affect page content? Will it be useful for analyzing traffic data? If the answer to either of these questions is no, you should exclude the parameter from your URLs to simplify reporting.
