For many people using Google Analytics, a major drawback when analyzing data is the max 500 rows constraint in their reports.  For a person who wants to look at all keywords & search phrases over the last year, it could take hours to export and compile.

The easiest way to get this data without running numerous reports is to add “&limit=50000” to the end of your URL.  Although you will still see 500 lines in the browser being displayed, when you export you will be exporting all rows up to the 50,000 line mark.
