With Blogger, a good start is the widgets. Those buttons and other items you can add on the side. An example is "Total Page Views" or "Blog Archive." Adding and rearranging those widgets are a good place to start when revamping your blog.
Content is another thing. How's your content? Is there enough of it? Fixing how much and how many posts you make is another area on your blog that you can revamp.
Background colors and word colors and fonts are another thing you can customize. You can choose a different theme "Awesome inc." Or "Simple."
Share your blog and help it grow. Not just with views but with content. Good luck with revamping your blog. I have a blog on Blogger as well. If you want, I can take a look at your blog. Other than that, I wish you the best of luck.
