Though some 80,000 blogs are being created every day, 10-20 percent of them may be spam, according to Umbria Communications, which monitors consumer-generated media, reports AdWeek. Umbria's research has found that 2.7 million blogs out of 20.3 million are spam blogs, or splogs, many of which are created solely as a shady marketing tactic, using stolen web content, often via RSS feeds, to profit from contextual ad programs.
Umbria examined blog search results in October from Technorati, IceRocket and BlogPulse, finding that on average 44 of the top 100 results were splogs.
Google's Blogger tool is often pointed to as a major culprit, because its open application program interface (API) has made it easier to mass-produce splogs via computer programs, according to Umbria CEO Howard Kaushansky.
