Articles posted on Blogspot, Wordpress and other blog hosts may be delayed or may not be indexed by Google. Such websites are not guaranteed to be indexed right away because Google is constantly checking its content and links. If you try to observe and post latest articles on DiggItLive, these are not indexed in that instant, unlike before; Google will index the latest articles from DiggItLive without any delay.
Blog authors have nothing to worry about it, in fact, Blogspot or Wordpress websites are still displayed in Google's search engine results. Just follow the rules and regulations in order to avoid such problems like being banned. Relevancy is the key here. Prevent doing any unethical manner such as violating the Terms and Condition of a search engine or black hat. Usually, search engine optimization techniques break search engine rules and regulations. Techniques like that unethically present content in a different visual or non-visual way to search engine spiders and search engine users, so that their website become visible and increase their website traffic.
