SEARCH ENGINE ALGORITHMS

PageRank Algorithm PageRank Algorithm, originated from Google’s founder,LarryPage, is used to identify the importance of web-pagesdivided in levels of 1-10 of which 10 represents full score, thehigher PR value (PageRank value), the more popular the pages.as in (1): when the PR value of a website has its score as 1, it means that this website has not popularity while the PR valueof 7-10 indicates that such website is very popular (or extremely important) [2]. Supposing Page-A has its page-t1, t2,and… tn linked to it, then Page-A has its PR value algorithm asfollows:PR(A)=(1-d)+d{PR(t1)/C(t1) … PR(tn)/C(tn)}

HillTop AlgorithmThere exists a fundamental flaw for PageRank Algorithmsince an absolute “importance value” is assigned to a webpagebased on its linked quantity and quality. However, the”PageRank value” is not a word for a query, so even when awebpage only occasionally mentions key word departing froma thematic query in the content, the page can also obtain ahigher ranking because of its high level of “PageRank value”[3].The Hilltop Algorithm is a fast positioning method subject to classification of “experts” proposed by Krishna Bharat andGeorge A. Mihaila, which has been applied by Google to thefront-end of Pagerank. That is, the request is treated firstly when it reaches using Hilltop Algorithm and given weight. Secondly, when nothing is searched out, it returns to “0” afterwhich the Pagerank Algorithm is used for calculations. Finally,related ranking is conducted according to the result upon the weighing of two algorithms

New Algorithm for Search EnginesAt present, in order to provide users the accurate results searched in a more scientific and rational way, Google uses itssequencing technology combining PageRank and HillTop todetermine the ranking of a webpage. Such a new algorithm hasits formula as follows:{(1-d)+a(RS)}*{(1-e)+b(PR*fb)}*{(1-f)+c(LS)} Of which, a, b and c are the regulation controls of weightand d, e, f are the damping controls while fb is the factor base.The new algorithm consists of three parts, the RS CorrelationScores, PR Page Rank Scores and the LS Industry

Tactics for Domain Name and HostIn the initial planning of a website, the selection of a domain name is also an important factor related to the searchengine optimization (SEO) of a enterprise’s website. A searchengine pays priorities to different domain name suffixes,especially to domain names with suffixes like edu or govHowever, this class of domain names can only be used by theeducation sector and government agencies while a corporate website has no right to apply for any registration. Under thesame circumstances, non-commercial website suffixes like .organd .net have more advantages for a higher ranking than .com.For Chinese websites, the Chinese domain suffixes of .cnand .com.cn have certain advantages than .com of non-regionalnature.As for a website space, it should be ensured that the storage space of web-pages is considered by a search engine to be “safe” without any contrary to the relevant rules? “Safe”pointed out here includes two aspects, namely, the runningstability of the space and its network environment.

Tactics for Website ContentThe actual content of a website is an important factor of theoptimization strategies for a website. When a website isxpected to be searched in the front pages among the search results, then real content thereof is needed. The search engine spiders can only determine the quality of a website based on its content rather than judging from pictures or flash animations. All pages should be provided with enough content to be searched by a search engine as index. This is the basic need for the successful optimization tactics for a search engine[4].

Tactics for Keywords Keywords are a factor for mathematical operations using search engine algorithm. It is used to determine the correlation between several billions of web-pages and the specific search. Those deemed as the most relevant to a keyword by search algorithms will be arranged in sequence[5]. So, it should identify the core keyword in the position and perspective of a customer as far as possible. In order to get a better ranking for a website, the density of keywords must be defined well within the scope allowed by search engines. Some studies have shown that the density of keywords within 2% -8% is thought to be useful for the improving of a website’s ranking. On the contrary, excessive use of keywords will result in keywordstuffing which would be difficult to read to cause loss of visiting flow rate[6]

Tactics for Links Links are the soul of a website, through whose hyperlinks users may obtain a wealth of website content. Besides, the search engine spider also tracks in-depth layers of a website’s links to complete the crawl of information of a website. Search engines, especially Google, will determine a website’s ranking basically subject to the number of high-quality external links pointing to this website, i.e., external links or reverse links known as inbound links or back-links. The outbound links to other sites from a website as well as the links connecting pages each other within a website would also bring about more or less impact onto rankings[7]. https://arudhrainnovations.com/
