Track Indexed Page Count over time for you and your competitors.

Indexed page count is the number of pages in a site that the search engines have discovered. Search engines weigh their search results heavily towards sites with a significant number of related pages. Too few pages provides little opportunity for keyphrase diversification, since any one page on the site can focus on only a limited number of phrases. Increasing a site's page count should increase the effectiveness of your search engine optimization efforts, and provide ample opportunity for keyphrase diversity.
