In 2011, blocking went main stream. Tiny Blekko kicked things off, followed soon by Google. There’s a good chance that Bing will eventually do the same.
Bp: Personal Blocking
Blocking allows anyone who doesn’t like a search result from a site to block that site from ever appearing again in their search results.
It’s as if everyone gets to be their own personal spam police. For sites that are banned, you won’t know the user has blocked you, nor will you be riincluded after a set time period expires.

Bt: Trust Blocking
Hey, who cares if a few people block you! There’s always plenty of other fish in the sea. They’ll still see you. Then again, maybe they won’t.
See, both Blekko and Google also use the aggregate blocking activity by their searchers as a negative ranking factor. Sites that are blocked by lots of individuals are effectively being nominated for overall blocking, or at least a penalty downgrade.
Bottom line? You want an engaging, quality site that’s not going to be blocked by individuals, lest you face a more widespread penalty.
