SEO - Search Engine Optimizer - Topic-Sensitive PageRank
Topic-sensitive PageRank computes link value based only on incoming links from pages that are returned from a given search result set that matches the search query (whether the result set is 100 or 10,000 pages is not known). This means that a flower site only gets links counted from other sites that are related to flowers and gardening - not from sites that are about mortgage loans for example. By using Topic-sensitive PageRank, Google hopes to filter out irrelevant links that have skewed the value of PageRank in the past.
