The internet is really all about content, be they images, text, animation or video or a mix thereof. Your blog site will certainly benefit from articles or posts with interesting, entertaining and thought-provoking content. They are sure to attract visitors and even get other blog owners to link to your site. But it should stand out above other blogs of the same content. You need to be unique.
Quality writing and original posts create a steady influx of readers to your site. Having unique content can also prevent penalties that some search engines like Google might otherwise impose if your site has duplicate content with one that has a high page rank. Just be sure that you sustain your site’s content uniqueness. The last you want is to lose your reader base that’s you’ve taken pains to build up.
