GA and other 3rd party tools work well for small business. As companies grow they should invest in moving clickstream analysis in house. The lack of visibility into bot detection makes GA and other 3rd party tools sub optimal solutions.
As "web stats" - sure. GA is a great alternative to parsing your own server logs, which doesn't make sense to SMB.
But ROI? GA will tell you absolutely nothing about why nobody cares about your product or service, or why your competitor X is succeeding while you are not.
You will get what you pay for, simple click statistics, but don't expect any business insights on ROI.
