Before install a more (and new) plugins on your blog, think deeply if you need them, because the more plugins you install, the slower the website uploads. For example, look for plugins that covers – more or less – the same functions, All in One SEO Pack and Worpress SEO works quite the same, so choose one and discard the another, and if it’s already installed, feel free to uninstall it. In addition, XML Sitemaps it’s already included on WordPress SEO plugin, so if you go for this one, you don’t need to install XML Sitemaps because it doesn’t require another plugin. We can look at Permalinks also, they’re working customized on the blog, therefore they don’t need a plugin to carry on with their properties.
Bonus: let me give you an extra suggestion for a bunch of essential plugins that you may want to install in your blog for improve its performance:
- Disqus Comment System.

- W3 Total Cache.
- WP Smush .it.
