Premium SEO Pack has a lot of features that make the plugin fairly appealing but from testing the plugin is rather bulky and can bring your website to a stop. While it comes with many features it does not seem to do any of them particularly well. I find it to be slow clunky and it didn’t do that much for my SEO. In fact Yoast has done better for my SEO and it is a free plugin. However, the plugin has tools that could in theory increase traffic through backlinks and it comes with some features that are not found in the free version of Yoast that are actually quite handy.
