A sping (for spam ping ) is a ping sent from a splog (spam blog ) to make recipients think content of interest has been updated although that may not be the case. The intention is to lead users to the splog where they will be exposed to marketing or advertising content. Frequent spings to sites like technorati.com will cause a splog to appear quite active, raising its page ranking and therefore its visibility. According to various reports, 60-75% of all pings sent from blogs are actually spings.
