Regex and Google Analytics
First off we have the standards:
* ^s*[^s]+s*$ – one keyword
* ^s*[^s]+(s+[^s]+){1}s*$ – two keywords
* ^s*[^s]+(s+[^s]+){2}s*$ – three keywords
* ^s*[^s]+(s+[^s]+){3}s*$ – four keywords
* etc.
You can also use ranges (remember my post on Regex?) to sort your keywords into groups. Unfortunately, while the range command {x,y} works just fine in filters, it won’t work in advanced segments.
* ^s*[^s]+(s+[^s]+){1,4}s*$ – two to five keywords
* ^s*[^s]+(s+[^s]+){5,}s* – six or more keywords
