If you have a wordpress blog that you dont pay much attention to then you should install the wp-o-matic wordpress plugin which will turn your blog into an Autoblog.  What this plugin does is automatically adds articles to your blog via an autofeed that pulls feeds from website rss feeds you specify.  You can set it to run at specified times throughout the day adding as many articles as you like.  You will need to setup a cron job via your hosting account in order for it to work.

When you download the plugin simply extract the files locally to your computer and then FTP to your server and upload the plugin folder to the following directory in your hosting account:

Root/wp-content/plugins/

Login to wordpress and active at the plugin

Then under settings click on wp-o-matic and start the installation process.  Follow the onscreen instructions which asks you to setup a cron job.  If your not sure how to setup a cron job follow the following video which shows you how to install and setup the wp-o-matic plugin:

 You can add as many different campaigns as you like

Although if you can i still would recommend your own unique content as your blog will highly benefit from adding unique articles that aren’t duplicated from another blog.
