Google Analytics

There are many which provide help you to collects statistics about your site. econsultant lists 12 sites under web analytics. I have checked following

1. MyBlogLog provides basic things such as how many clicks, incoming links and outgoing links


2. Google Analytics - This is just great! You have all you need. You can see how many page views, how many visitors, from unique visitors, returning visitors, geographical area of the visitors, incoming and outgoing links, how long the users are staying(This information lets you know if users directed to your blog actually interested in) . That too graphical representation of executive summary and there are details reports.
   




3. Clicky Click - This is another way of putting it but does not tell you from where are the visitors coming only IP is provided. This is the big missing feature compared to Google Analytics but presentation is intresting though there arent any graphs

There are lot of others which of offer stats like sitemeter which give you aggregate of the number of visits, for high volume pages there is alexa widget
