HI All I need to ask you some things about improving our blog. I want to track a couple of things about my posts that I write. I know that if we use the Analytics from Google we can track our details of the visitors. Do we need it to do for every page or for every post. But a post is a separate page after all - if we click on its title. Secondly, as comments can be counted separately for every post, can views be counted separately for all the posts and articles too? I mean where there is the "comments", can we manipulated the HTML code to get the views too? Thirdly how can I get the "thumbs up" button from facebook that we see near some articles? And finally how about the "Tweet" and "Retweet" buttons. Please tell me how to get these for my posts separeatly and in every post that I publish as an article?
