A solid page rank is important to ensure that search engines index a website quickly and rank the pages high for specific keywords. This ensures that a web page will for instance, come up on the first page of Google or Yahoo search results for a keyword relevant to the main product or topic of the web page. If a web page doesn’t come up under the first 20 results it will simply not get enough traffic. Having a page rank of 5/10 at Google is an impressive feat to say the least. What is more impressive is that a company doesn’t need to break the bank in order to do so.
The example is Limopros which is a sit that was moved from 3 to 6 Google Page Rank within 12 month span of time and earned the site a whopping 350% increase in traffic, allowed the customer to cut off all PPC making the company very profitable.
