Search results are not all worth the same. The #1 gets more click throughs and views than the #54 (who looks at # 167?) and the Top 20 results get 90% of the traffic. RankTank weights the Top 20 search results according to their position in the rankings. RankTank also classifies each search result by who claims it - the Enterprise/Brand, Consumers, the Media or Others. You enter the Top 20 results for any query into RankTank and RankTank calculates who owns the lion's share of the value of the Top 20 results-- the most critical branding, reputation and selling space online. RankTank works for traditional Web search and for social Web search.
