Themes are templates which are outlook and design of the blog. Free and premium both themes are available on the websites. Premium themes are paid themes which are used by professionals, companies and pro-bloggers. Free themes are widely used that’s why professional bloggers don’t prefer free themes. Theme developers also keep hidden credit links of their blogs and websites in the free themes which make negative effect on the theme users. Premium WordPress themes are recommended by professionals and pro-bloggers. Premium WordPress themes are free of such code injections and other errors. Blogs which are being operated on Premium WordPress themes always get better ranking.
