What kind of website will be attacked in this algorithm update? Let's take a look at some of the highlights of this "Web Spam algorithm Update":

1, Google introduced a number of different elements of the identification system to detect the site

Search engine in some way to determine the Web site related to the cluster, such as on the same host, looking for these pages as the goal of the bridge page and related articles, once determined that this is a cluster, the cluster within the file may receive search engine retrieval, see if this text belongs to their internal text, If it is not found to be an external link into the text, it will be considered cheating, and in the detection of internal files, the search engine will focus on the contents of meta tags, if found in meta tags stuffed with duplicate keywords, or have hidden in the page text, Or the page contains a lot of irrelevant links, so unfortunately, such a site is also included in the search Engine spam blacklist.

2, use the statistical language model to identify the Web page

In this Google algorithm update, Google has also been more advanced development, they use statistical language model, speech recognition, machine translation to identify the Web page "unnatural word distribution", and even determine the synonyms in the context. So Google in the face of huge data information, there is a more simple algorithm work.
