1) Remember who your audience is and write for them.
2) Make each blog post a conversation, encourage comments, add comments, keep it going. Give the people visiting your blog a reason to come back.
3) Read a lot of other blogs – seeing what others are doing shows you the possibilities.
1. Whos.amung.us
This widget allows us to see how many visitors we have had on our blog and where in the world they live.
2. Shelfari
The Shelfari widget allows you to showcase favorite books that you are reading in your class. Easy to use and install. The first step is to sign up for Safari and then you start to look for favourite books, simple. Shelfari is added as a widget and you can find the embed code for your shelf on their site. When you sign up you may want to sign up for a class Shelfari so your own personal books don’t show up on the shelf.
3. Google Translate
This widget is available right in the blogger platform. You have so many languages to choose from. If you don’t want Google Translate, how about looking for another widget in the Blogger platform.
