Google Analytics is a website owner’s favorite tool for analyzing website usage: it shows where users came from, their geographical location, what pages they visited, how long they lingered, etc. It’s available free of charge from Google.
One limitation of Google Analytics is that its website usage reports are delayed by 24 hours. If you can’t wait that long, now you can sign up with Google Analytics Premium. It offers real-time website usage information, training, a Service Level Agreement (SLA), 24 hour telephone support, and a dedicated account executive. Its cost: $150,000 per year.
For high-volume e-commerce sites with time-sensitive items (think eBay, Amazon, etc.), Google Analytics Premium may make sense.
For now, I’ll remain with the plain-Jane free of charge Google Analytics.
