Pagerank directories promote themselves by offering website owners the chance to promote their sites on content pages with a high Google pagerank. Pagerank is one of the many factors Google uses when determining the relevance of your website in relation to various search queries. It is based on the idea that the more sites linking to your own, the more popular and better it must be. One way to boost your rankings is to submit your site details to directories which offer links on high ranking pages. The more high pageranked sites your website appears on the better for your eventual search rankings.
