When running a website, it’s important to know who your visitors are. How many are there? Are there enough to pay for your site? Are the numbers growing? Where do they come from (physically / electronically)? How do they get to your site? What were they looking for? Are you giving it to them? Which pages did they visit? What browser were they using? Does your site look right on their browser? How long did they stay on your site? Was it easy for them to find what they were looking for? Did they convert, from visitor to customer? Did they do what you expected?
