PageRank Increasing for Search Engines

How to raise PageRank of the web-pages? This question is getting more urgent today. It’s all because this parameter affects the site position in search result list. Here I want to suggest you an easy way to increase PageRank of your pages only by small changes in them. If you are carrying the problem of […]

Website creation and PageRank

What is PageRank? Google uses PageRank of just PR to define the importance of a page. It’s wrong to think that PageRank is the main factor in page ranking i.e. positions defining in search results. But understanding the principles of its forming may help to understand the logic of search engines when defining the ‘weight’ […]

Backlinks and Google PageRank

First of all there are two PageRank indexes. The first one shows a number in Google Toolbar, characterizing the PageRank of your page and is updated every 3-4 months. Another PageRank is always updated and is used in search engine ranking algorithm. The first one is used only by web-masters for rating indication and the […]

Factors affecting PageRank

Frequent site updates don’t raise PageRank automatically. A high PageRank can’t guarantee high positions in search results. The DMOZ and the Yahoo! catalogues don’t raise PageRank automatically. .edu and .gov sites don’t raise PageRank automatically. Other pages may have higher PageRank than the front page. The Wikipedia site links don’t raise PageRank automatically. The links […]

PageRank explained

The first company to receive the patent for outbound links accounting system was Google Inc. This algorithm was named PageRank (PR). Here goes some information about this algorithm and its possible affection the search results ranking process. PageRank (PR) index calculation is made separately for each web-page. This index is defined according to the citation […]

How precise is Google Toolbar?

Google Toolbar shows a site weight not very precisely, but it’s the only tool giving you at least some information any time you want. If you know the toolbar limitations you know at least what you see. So there are two limits in Google Toolbar: 1. Sometimes the toolbar defines weight approximately. If you open […]

Algorithms Google PageRank

The original algorithm of PageRank was described by Lawrence Page and Sergey Brin. It’s calculated by the formula: PageRank(A) = (1-d) + d(PageRank(T1)/C(T1) + … + PageRank(Tn)/C(Tn)) Where – PageRank(A) is the PageRank of the A page, – PageRank(Ti) is the PageRank of the Ti page which has a link to the A, – C(Ti) […]

Why is a page with a lower PageRank displayed above mine?

I want to thank Phil Craven for the given right to publish the information. You may find the original article at PageRank doesn’t define the page’s rating in search results itself. If it were so, all the PageRank 10 pages were shown on the top of the results and after them PageRank 9 pages […]

PageRank History

PageRank is one of the link ranking algorithms. This algorithm is applied to a collection of documents linked by the hyperlinks  (such as web-sites of the World Wide Web), and assigns each of them a certain numeric value, measuring the “importance” or the “authority” among the other documents. Commonly speaking the algorithm may be applied […]

Smart Media Management

A system is called ‘smart’ if a user perceives the actions and reactions of the system as being smart. Media is therefore managed smartly if a computer system helps a user to perform an extensive set of operations on a large media database quickly, efficiently, and conveniently. Such operations include searching, browsing, manipulating, sharing, and […]

Automated Inspection

Manufacturers who depend on automated inspection systems for process monitoring and quality control generate large databases of product and defect imagery. As these image repositories grow in size, the manufacturer’s ability to reuse this data is limited by the large volumes, and the difficulties and intricacies of automating the description of imagery for cataloging, searching, […]

Photodiodes See the Light

The purpose of any photodetector is to convert electromagnetic radiation into an electronic signal—ideally one that is proportional to incident light intensity. Because they are compact, versatile, and can be produced economically in high volume, p-i-n photodiodes have become the detector of choice in applications from biomedical instrumentation to telecommunications.
