Premium SEO Pack not a bad plugin

But, in the paid version, judging by the reviews of the plugin a lot of unnecessary, and in the free version you need knowledge to correctly configure the plugin, also developers do not know or ignore the news, the title in Google can be written up to 65 signs, and description can make up to 320 signs in Google, and this is a drawback, in the plugin, and in the end I want to say that working with any plugin requires knowledge of SEO – one plugin on the site anything can not do!
