Assuming that you have successfully set up your blog and theme, the next logical step to retrieve your blog to the next level is to use a very important plugin for most of the WordPress sites.

I have collected a list of the most useful and important plugins that you should start using on your WordPress blog. Here's the list:

After visitors come to your website, you want to make sure that the website remains fast and keep online. W3 Total cache Plugin will help you with it if you don't want to spend extra money in server resources.

Even if you can spend more money on the server, it's still a good idea to use this plugin to get the most out of your server now. However, if you don't want to tamper with too many choices and want something that is not only effective but it is easy to arrange too, you must try WP Super Cache.
