When it comes to increasing traffic and to track all visitors on your blog, you can't beat Feedjit. I have one on all 3 of my blogs and not only is it overly simple to configure and install, it's also free.
What does it do? It keeps track of all your blog visitors; it will show where your visitor came from, what country, state, etc. and also if they visited your blog by clicking on another blog or site's link. It also shows how they left your site. For example, I have 2 blogs that offer download links for scrap freebies; if that visitor clicks on the download link, it shows on Feedjit. This widget is a wonderful addition to any blog, and it's attractive.
If you go to Feedjit.com you will first see options to take advantage of the Feedjit Pro and Advanced Versions. If you want a free version, simply click at the top where it says "Plans and Pricing." Under Feedjit Pro you will see small text that says "You can get free live traffic feed on this page" - click this link for your free version. This will take you to the page where you can then customize your colors to match your blog and then you can automatically have it installed on your blog.
After viewing it on your blog, you will see on the widget "Put your face here" - click that and you will be directed to Feedjit where you can sign in either to Twitter to get more followers, to Facebook, or to your blog where you will get more traffic. Two of my blogs are linked to Twitter (and I have more followers because of it) and my newest blog is linked to that blog so I can get more traffic. You can upload a picture that will appear not only on your own Feedjit widget, but to any blog you visit that has Feedjit installed. When you visit another's blog, your picture and identity will appear with a direct link to your own blog or website. This naturally makes others, seeing as how you visited their blog, want to visit yours, therefore giving you more traffic.
I have clicked on many of my visitor's links to view their blog or to leave a thank you for visiting mine. Some people however, do not wish to have a picture installed, so you will be provided with only the place they came from. It is much better to have your profile already installed through Feedjit, so that your direct link will show.
I love being able to see right away the visitors, traffic and links, and besides that, it looks good!
