I have been curious to know if the All-in-one-SEO plugin really makes a difference on your wordpress blog. I have it on mine, but I'm wondering what the difference is WITHOUT it?
It allows you to add meta-keywords,meta description etc to individual posts..
If you use it religiously for every post you make, it allows you to quickly build up a more search engine friendly database of your articles, as you can use it to write your title for search engines not the readers.
The best one according to my opinion is the "Canonical" which preventing duplicate content.
And of course with AIOSP you can make the <title> and <h1> different, so you will get a better keyword variation.

Wordpress handles about 80% - 90% of the search engine optimization by itself. And that is without any add-ons.
With that in mind, I do not recommend any plug-ins that are supposed to SEO your wordpress blog.
The only thing that I really recommend is that you change your permalink structure. So that the URL uses long tail keywords.
