1. Customize your blog. This will make it look new and shiny, ready for some more posts. Try and Customize your blog so that it matches what it is about.
2. Use an anti-spam plugin for WordPress to avoid spam. Akismet is a good anti-spam plugin for WordPress.
3. Put some widgets on your blog. This makes your blog look good because the widgets are useful.
4. Check for spelling mistakes before publishing a post. Correct any spelling mistakes before publishing a post.
