I use Google Analytics to measure stats for my blog. It is just starting and hasn’t appeared in search results yet so the numbers are fairly low. It is pretty easy for someone new to use it and gain insights about their website though. There is even a “real time” function where you can see who is on your website at the moment. Another advantage is you can see where your visitors are coming from geographically. It also shows you how your visitors are being forwarded to your website, be in organic search, referral, social or direct.
Organic search comes from a search engine such as Google or Bing. Referral is from another website putting up a link. Social is from Facebook, Twitter, or another social media site. Direct is when someone puts your website’s URL directly into their web browser.
