New trends in search engine ranking algorithms-search engine technology

As we all know, GOOGLE's PageRank set page KEYWORD relevance (TITLE, HEADING, DESCRIPTION, anchor text, alt tag, CONTENT, keyword density/PLACEMENTS, PAGESIZE) it is a comprehensive ranking algorithm integrated with link popularity (incoming links, outbound links, insite cross links). It is also the most advanced algorithm for commercial applications.
A little high, a little high, around PAGERANK many SEO experts then came up with a lot of countermeasures to optimize the website, especially in the external links took a lot of time. It can be said that SEO's internal and external optimization technologies and strategies for PAGERANK websites are quite mature, and even reach the level of legitimate SPAMMING.

Therefore, GOOGLE has also adjusted PAGERANK to improve its sensitivity in monitoring various cheating methods, such as Bridge pages, Ghost Pages, ip cloaking, and link farm). (SHIT! Once upon a while, I believed what an expert in China said: "link is everything, and any external link is useful." it almost hurt my website. Fortunately, my website's external link is "solid ", not blocked by GOOGLE :)). But in general, these adjustments do not fundamentally solve the problem of legitimate SEO cheating.

At present, many foreign search engine experts have studied this issue and put forward corresponding solutions. The most popular among them is to use "authoritative non-associated external links" as an important factor in determining rankings. When you hear this, you may think about logging on to the DMOZ, YAHOO, and other directories! But it is not completely correct !! The importance of these directories is increasing, but the "authoritative unassociated external links" mentioned in this article indicates whether a specific keyword page appears in the corresponding authoritative website link. For example: if the keyword is PHARMACEUTICALS (drug) and appears on a webpage link of the us fda website, it will be given a high "authority" score by the search engine. Generally speaking, I think the authoritative website they refer to refers to some websites of well-known industry associations, websites of academic institutions, websites of government agencies, websites of enterprises with certain influences, and various authoritative directories, that is to say, if the website you link has a certain authority in terms of specific keywords and related words, it is a good link (note: non-associated websites). The more such links, the better.

What is "non-associated website "? The best answer is to give you a definition of "associated websites:
-- The first three eight bytes of the IP address are the same
-- The primary domain name is the same. Both WWW. ABC. COM and WWW. ABC. COM. CN or SEO. ABC. COM are associated websites.
