I know a site that I run on Wordpress. I know there are some SEO plugins for Wordpress like e.g. "All in One SEO Pack" or "SEO Slugs" which removes common words like 'a', 'the', 'in' from post slugs to improve SEO.

So I just wonder if I shall install these plugins and if both of them? Are they good and will they really improve SEO of my WP blog?

I also wonder if there is anything else that shall be done on every WP blog to improve its SEO?
