Premium Wordpress Plugins

Hey Guys , I was wondering if we could share what you think of some premium wordpress plugins that work well together on the same blog.

BackUp Buddy - this is my favorite premium plugin. it makes it easy to make exact copies of sites with only one click

WP-Robot - makes autoblogs, although i think Carty's Autoblogging Software/Autoblog Samurai is better

SEOPressor - checks your on-page seo, although it's easy to do this manually

PHPurchase - Creates a very advanced shopping cart

Scribe SEO Plugin - not sure what this one does but it's ridiculously expensive. something seo related obviously but i doubt its worth the price

Indexing Tool Plugin - helps your backlinks get indexed

Backlinks Energizer - helps your backlinks get indexed

WPSyndicator - posts your sites content to Web20 sites

WPUnique - makes your sites content unique

Onlywire - posts your sites content to social bookmarking sites. has a free version, but you have to pay to use it without limits

thats all i can think of

Caffeinated Content?
