PageRank is a value rating system assigned by Google to each website. The scale runs from zero to 10 and (generally speaking) the higher the number the more popular/credible the website according to Google. The rating scale is exponential meaning that the difference between a 1 and a 2 is not much, while the difference between a PageRank 5 and 6 is often significant. If you have any PageRank at all, that’s a good thing. Almost 50% of all domains have a PageRank zero. If your PageRank is low – don’t worry – a good SEO service can help increase it like us.
