Blekko Bans 1.1 Million Spammy Domains Via New Algorithm
They’re calling the new algorithm “AdSpam.” “One of the strongest signals that a page is spam is aggressive participation in self-service
online advertising networks,” says the company. When they compare low quality sites (based on existing signals) and see lots of keyword based ads alongside that content, it’s very likely to be blocked.
“Domains with low quality content plus keyword ads are “machines that print money,” says Blekko CEO Rich Skrenta. “Machines that print money will be exploited.”
Blekko is processing around 1 million search queries per day and has 500,000 unique monthly visitors, he says.
