A class of linked websites with an ignominious and contemptible ranking is termed as bad Neighbourhood. Search engines degrade the rankings of the sites deemed as bad neighbors, as to avoid them from faking their rankings and trying to affect the quality and plausibility of a certified site. A site falls into the category of a bad neighborhood, either due to their abysmal and substandard behavior or their connection with shady and unrespectable sites. If you come across a site involving way more than normal spamming, lame advertisements or impoverished style of writing, then you may regard it to be a bad neighbor and block it or remove it from your search engine as soon as possible.
