From my personal experience, I've found that almost every major CMS has some sort of SEO plugin which usually enhances the default SEO features if any are built-in. This is especially true for WordPress which has a lot of useful ones but are often not too newbie friendly unfortunately. With that said, do you use any and if so, were you satisfied? I've been satisfied with the ones I've used on WP and on my forums.
I installed All in One SEO plugin on my blog. I think this plugin is quite newbie friendly as I know how to use it. After all, I think the default SEO features on Wordpress are advanced enough to help you optimize your blog.
