PageRank is one of factors that Google uses to evaluate your web site and determine its position in Google search engine results. PageRank is a number from 0 to 10.
Generally, if your web site has a higher PageRank, it will appear earlier in Google search results pages, all other factors being equal. In fact, you can see a significant improvement in where your pages appear in search engine results when your PageRank increases.
