I agree, the SEO plugin is helpful. I use the one by Yoast. I think I need to check out the cache plugin. One of the most helpful plugins, I find essential is Akismet. This keeps the comment spam out of my inbox. I find it amazing, how many people resort to trying to post nonsense ads. Like how they can help me build more traffic. I seriously doubt they even have a blog or website themselves. Let alone know what they are talking about.
