What are you using for Content? Mod or CMS?
 

I have been using Postnuke for content for many years then got VBulletin and migrated everything over to it, my SEO has taken a big dive since then, I am using vbnews and VBArticles and VBSEO, I find that my site has gone down about 10 places on Google and Yahoo for "PBX".
I am contemplating going back to postnuke or using Joomla, but was wondering what you guys are using and what success rate your having with content and search engine placement.
Also what article system is easiest to manage and does news and content in one?

Thanks for your suggesitons/feedback.

Joomla for me, takes a bit of getting used to but tons of skins and mods

Whats your traffic from search engines like though?

A ton of sites took a dive in rankings recently and they continue to fluctuate all the time anymore it seems. I'd watch the total number of referrers you are getting, and what keywords are sending traffic and how much traffic from each one.

Use a Analytic program such as Google Analytics to track it if you need to
