Admin Link development & Spam mass
09 Nov 05: Four incredibly intelligent Californians, Zoltan Gyongyi, Pavel Berkhin, Hector Garcia-Molina, and Jan Pedersen, released a whitepaper discussing a possible approach to identify links from spam domains. Their approach sheds light on some quite intriguing ideas on how Google might judge the top quality of inbound links.
Excellent links Vs Bad links
Since the Jagger update, Google seems to be emphasizing link relevance and link quality a lot more. Whilst relevance is pretty straight forward to understand, quality of an inbound link might be a foreign subject to those not involved in search engine marketing as part of their daily lives. So let’s 1st talk about excellent links versus poor links. Not all links are equal. Links from common websites carry a lot more weight than links from virtually unknown websites.
It is a well-recognized truth that Google’s initial success lay in their capacity to find web sites and rank them based on links from other internet sites. As Google’s popularity grew, some webmasters tried to outsmart the Google algorithm by falsely inflating the importance of their internet site with unnatural inbound link development. Links that are developed in such a way, with the mere intention of fooling Google’s algorithm to gain higher rankings are regarded as to be bad links.
