Some engines simply counted the number of links coming into a page (inbound links), but Google took the idea further. Each inbound link comes from a page which itself has inbound links. The more inbound links on the linking page, the more important that page is and, therefore, the more important the link to our page is.  So Google gives more weight to inbound links from important pages that it does to inbound links from lesser pages.

Google is the world’s number one search engine, and currently provides the results for around 80% of all the searches done in the world. Because of that, it is vitally important for any website that relies on search engine traffic to do well in Google. Ranking  well in Google means making the site ‘important’ in Google’s eyes and, to do that, the site must have good inbound links – as many of them as possible, and preferably from important pages (pages with medium to high PageRank values).
