Pagerank is primarily a measure of a particular website’s incoming links. In order to increase your own pagerank, you will need links from sites that have a higher pagerank than yours. Ideally, the sites with the highest pagerank would be the most important; however, this is not often the case. Take a look at the top ten results for any keyword and you will see many instances of pages with a lower pagerank outranking those with a higher pagerank.
When the next PR update happens, it is unlikely to give you any sort of rankings boost, whatsoever. The reason for this is that there are over 100 different factors that Google takes into consideration when determining a page’s position in the search engine results, and pagerank is only one of those factors. Google is constantly getting smarter at determining what sites deserve the top positions in the search results. As Google has evolved, pagerank has played less of a role in that determination.
So instead of concerning yourself with just one rankings factor, your website will fare much better if you take a holistic approach to your SEO and try to satisfy all of the other rankings factors. Although, it is nice to be given a score from Google in the form of a pagerank, the only score that really matters is where your site ranks in the search engines and how much traffic it gets. Pagerank does not mean traffic, so the best thing to do is to ignore the next PR update altogether and work on things that can bring traffic to your site.
