One of the grand research and industrial challenges in recent years is efficient web search, inherently involving the issue of page ranking. In this paper we address the issue of representing and quantifying web ranking trends as a measure of web pages. We study the rank position of a web page among different snapshots of the web graph and propose normalized measures of ranking trends that are comparable among web graph snapshots of different sizes. We define the rank changerate (racer) as a measure quantifying the web graph evolution. Thereafter, we examine different ways to aggregate the rank change rates and quantify the trends over a group of web pages. We outline the problem of identifying highly dynamic web pages and discuss possible future work. In our experimental evaluation we study the dynamics of web pages, especially those highly ranked.
