Internet marketing agency Portent Interactive has published their statistical model for planning search engine ranking and clickthru.
The model follows Portent's "white hat" SEO philosophy, predicting potential for success based on a web site's size, level of code cleanliness and content relevance, and competition. Based on two calculations -- Relative Position Index (RPI) and Click-Through Prediction -- this mathematical model works across all major search engines, and provides a stable model for planning search engine campaigns.
RPI measures search engine optimization potential and progress. It's a logorithmic scale that measures what your rank is, or will be, given a level of optimization, competition and a specific search term. An RPI of 0, for example, means you rank dead last for that term, and can't move up without a lengthy campaign. An RPI of 5 would mean you rank in the top .001%.
CTP uses RPI and measures whether high rank for a given keyphrase is a reasonable goal for that particular web site.
