AutoBlog - AutoDelete + [Free WP Plugins]
I was looking for a solution and most people recommended i go for a dedicated hosting.
After doing a cost benefit analysis. i noticed the adsense income from the autoblog wasn't sufficient to cover for a dedicated host and leave some profits.
the autoblog I have is a news site and gets hundreds of news post daily. So I decided to keep it that way, a news site. any posts older than 14 days are deleted automatically.
Its a wordpress site that uses free plugins listed thus: [no aff. links]
PHP MyVideoBlog | Wordpress AutoBlogging Plugin (the lite version is free and works perfect for me)
SEO SearchTerms Tagging 2
Auto Delete Posts
I stopped using FeedWordPress reason being i wanted a video blog not text blog
hope this will be helpful to someone
