What is PageRank?

November 3rd, 2008

PageRank is a patented method to assign a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web. Google runs on a unique combination of advanced hardware and software. The speed of Google search we experience can be attributed in part to the efficiency of their search algorithm and partly to the thousands of low cost PC’s they’ve networked together to create a superfast search engine.

The heart of their software / search algorithm is PageRank, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University. And while they have dozens of engineers working to improve every aspect of Google on a daily basis, PageRank continues to provide the basis for all of our web search tools.

PageRank Explained

PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.” Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don’t match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page’s content (and the content of the pages linking to it) to determine if it’s a good match for your query.

Google Toolbar PageRank
The Google Toolbar’s PageRank feature displays a visited page’s PageRank as a whole number between 0 and 10. Google has not disclosed the precise method for determining a Toolbar PageRank value. Google representatives, such as engineer Matt Cutts, have publicly indicated that the Toolbar PageRank is republished about once every three months, indicating that the Toolbar PageRank values are generally unreliable measurements of actual PageRank value for most periods of the year.

False or spoofed PageRank

While the Pagerank shown in the Toolbar is considered to be accurate (at the time of publication by Google) for most sites, it must be noted that this value is also easily manipulated. A current flaw is that any low PageRank page that is redirected, via a 302 server header or a “Refresh” meta tag, to a high PageRank page causes the lower PageRank page to acquire the PageRank of the destination page. In theory a new, PR0 page with no incoming links can be redirected to the Google home page - which is a PageRank 10 - and by the next PageRank update the PageRank of the new page will be upgraded to a Page Rank of 10. This is called spoofing and is a known failing or bug in the system. Any page’s Page Rank can be spoofed to a higher or lower number of the webmaster’s choice and only Google has access to the real PageRank of the page. Spoofing is generally detected by running a Google search for a URL with questionable PageRank, as the results will display the URL of an entirely different site (the one redirected to) in its results.

Avoid six strategies to not get banned from SE

November 2nd, 2008

Most of webmasters do know the import of having high search engine rankings. High rankings means high traffic, translated into increased profit.. Webmasters look for all sorts of tactics to improve a website’s position in search results.. However you need to avoid some tactics, generally termed Black Hat SEO, because it may cause a website to be penalized /banned from search engines. So below are the six popular Black Hat search engine optimization tactics:
1. Keyword Stuffing:
The more often you use your keywords on a page, the higher you keyword density. However, search engines don’t look for exceptionally high keyword density, but reasonable keyword density. If you repeat your keywords too often, search engines might think that your website is spamming.
2. Cloaking
Cloaking is when websites serve one web page to search engine spiders and a different to human visitors. This can be used to mislead the search engine with regard to the content on the website.
There are, however, some methods of cloaking which are not regarded as a deceptive, such as delivering unique content to users based on their location, or allowing search engines to index password protected pages.
3. Hidden Text
Another method of deceiving search engines with regard to a website’s content is by including hidden text. Text can be rendered invisible by setting it as the same color as the background, using negative margins, or placing it in an invisible containing element.
4. Gateway Pages
Sometimes additional websites or web pages are created with the sole purpose of ranking highly in search engines and generating traffic for another website. If these pages provide no value to visitors and are only used for rankings, your website may be penalized.
5. URL Redirection
This occurs when a user, or search engine, is unknowingly redirected to another website. Sometimes this practice is used to acquire the pagerank of the destination page. At other times, it is used to redirect users to a malicious website.
6. Link Farms
Google Pagerank and other similar ranking algorithms for other search engines place a lot of weight on link popularity. Black Hat search engine optimizers often take advantage of this by creating something known as a link farm, which is consists of a community of websites which link to each other.
Search engines have gotten progressively smarter in their quest to deliver highly relevant search results. So even if these tactics give you some success, it will only be temporary and could result in an indefinite ban of your domain name.

March 4th, 2008

How time does run!! Have you the idea? I am able to fell that time is running so much faster for me. Time is a old gipsy man. I have failed to adjust my working time with the day’s time. I am not satisfied with my performance as I have failed to manage time properly. Now I am felling that it is running so much roughly for me.
And I have nothing to do but realizing the fact that I have not done my work.
Today I may go to my native place for meeting with my parents. But I am not sure weather I am able to manage time properly. My mental condition is not fully supported me to flow me this type of journey but I have to do this for my own interest.
Have you any idea to stop the fast running of time?
If any one can  then mail me please. I am waiting to learn how to stop it’s fast running. It ill me much as I failed to adjust myself with this journey.
