Hi! I was thinking about those article directories and I wonder if their articles are really good for a website??? I saw opinions about those articles badly affecting SEO but I don't know exactly how... Maybe because of the page rank or something... or simply because so much people are using them... they actually can fill an entire search engine first results page and there is no room for others to get placed high . On the other side I saw a site that do use free articles from article directories but and also original articles... and are actually placed on the first position on SERP. What is the real answer...??
