According to me Both Page Rank and search engine results Page are extremely important , but only Rating Page takes you to the top of the SERP and bring the relevant web traffic you need for your website. And to get a good keyword position to make a good SEO On Page , choose and make good use of keywords and wait for the result on the search engine results Page.
Good SERP is always more important. PR is just one of the factors that affects your SERP ranking. It also depends on what is the purpose of you domain: 1) if you are a link seller, then PR and SERP are both important 2) But if your purpose is to get good relevant traffic and generate business then PR is of no use.... only Good 1st page ranking on SERP on you desired keywords is important. hope that helps. thanks
Depend on what your goals are, I'd say. Most will say SERP, and I agree. But for example a higher PR will give you lower Adwords advertising costs, among other things.
Both of them have importance in internet marketing.if you want to sell some product on your site then your site PR is most important.and if you only need traffic and google result then SERP is important.
