Google PageRank Explained

Everybody using internet is aware of the power of Google. Google is everywhere whether its search engine, email, social networking, online marketing, blogging etc.

But most important of all these is it's search engine which share approximately 60% of all searches made all over the world.This explains the importance of rank SERP (Search Engine Results Page) fo Google.The higher the ranking on SERP the more free visitors you will get from Google.

While displaying the results for a particular query Google takes into consideration a lot of factors.

Two most impotant factors being (source - Google's Corporate Information) -
  • PageRank Technology
  • Hypertext-Matching Analysis.
Now here comes the importance of Google PageRank.

What is Google PageRank?

According to Google - PageRank is Google's view of importance of a webpage. Pagerank is given out of 10.

Thus a webpage with a higher pagerank will be more important in view of Google as compared to the one with lower pagerank. Hence, a webpage with a better pagerank will get higher position in the SERP.
e.g. A webpage with Google PageRank of 5/10 will be more important and hence placed higher in Google SERP than the webpage with Google PageRank of 3/10.

How does Google determines a PageRank for any webpage ?

Lets see what Google says -

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".

So Google takes into account the backlinks each webpage gets from different other webpages. Each backlink a webpage gets is considered as a vote by Google in the favour that webpage. But at the same time Google also analyzes the webpage from which a baclink is given.

Let's examine the following figure for some better understanding -


In the above figure A,B,C,D,E and F are different webpages. Here you can see that page C has got a higher pagerank than page E, even though it have fewer links as compared to page E. It's because of the importance of the page from which page C is receiving a link and also the number of outbound links from that page. In the above case as you can see page B has got most importance and is having only one outbound link to page C, so up to 90% of its PageRank is carried to page C.

In the essence, a page with higher baklinks from quality pages (those with higher pagerank) will have a better pagerank.

Thus, improving your Google PageRank helps you by getting you more visitors through search engines and ultimately can result into better revenue from your website/blog.

Do you have too many "real" friends on Facebook?

"Remember five years ago when no one had Facebook and you didn't know what the guy you took high school biology with was having for lunch?" Jimmy Kimmel asked the audience on his show last night. "Remember how that was fine? Let's go back to that."

If you didn't watch "Jimmy Kimmel Live" November 11, you might think Kimmel started a campaign to end Facebook, but he's not. Instead, he announced a new national holiday called "National Unfriend Day," where he encourages you to "cut out some of the friend fat in your life" on Facebook and otherwise.

Today, November 17, Kimmel wants you to look at all of your Facebook friends and decide: who is really your friend? A friend, as he says, is not someone who "asks what 'Harry Potter' character you are."

See two Video Presentations (watch one after another as they are logically connected):

On his show yesterday evening, Kimmel celebrated the arrival of National Unfriend Day with its very own anthem sung by country artists Brad Paisley and Darius Rucker.

To all the friends I've un'ed before
Who sent me quizzes about Jersey Shore
You made my life a hell
With your stupid LOL
To all the friends I've un'ed before
To all the guys from grammar school
Posting shirtless pictures by their pool
Your fat and sweaty back
Really makes me want to yak
To all the friends I've un'ed before
Our time on earth goes by so quickly
We have to make each moment great
So I cannot waste one more minute
Reading your dumb status update

Kimmel may have a point, but this rather funny joke of a holiday seems to be more a late night comedy sketch than an event manufactured out of real concern for the status of friendship.

Still, National UnFriend Day is good natured -- at least for those not being unfriended -- and you might even consider taking the day to cut some friend fat of our own.

Facebook had no immediate comment on how the festivities were being marked at company headquarters. Needless to say, Zuckerberg is not likely to be adding Kimmel to his friends list anytime soon.

TinEye – Reverse search using your Images

When you prepare your blog post, you may need to add several images, which will help your readers to understand better the content, or will make the post more attractive and readable. Let’s say, you have found an image but you are not satisfied with quality, resolution, or you prefer having the same pic, but without visible watermark. Definitely, you may continue image searching through the popular sites, but there might be difficulties to locate what you exactly need. Here, you find a new useful service - TinEye - a reverse image search engine.


Using it is quite simple. You submit an image to TinEye and find out where it came from, how it is being used, if modified versions of the image exist, or to find higher resolution versions. When you submit an image to be searched, TinEye creates a unique and compact digital signature or 'fingerprint' for it, then compares this fingerprint to every other image in the index to retrieve matches. TinEye can even find a partial fingerprint match.

Note that TinEye does not typically find similar images (i.e. a different image with the same subject matter); it finds exact matches including those that have been edited, like cropped or resized.

TinEye is the first image search engine on the web to use image identification technology rather than keywords, metadata or watermarks. It is free to use for non-commercial searching. TinEye regularly crawls the web, looking for new images, and in addition accepts contributions of complete online image collections. To date, TinEye has indexed out 1.8 million images from the web to help you find what you're looking for.

Examples of use

    • Find out where an image came from, or get more information about it
    • Research or track the appearance of an image online
    • Find higher resolution versions of an image
    • Locate web pages that make use of an image you have created
    • Discover modified or edited versions of an image
Free services limitation

The free for non-commercial use version of TinEye at tineye.com allows you to do up to 50 searches per day, up to 150 searches per week.


TinEye must be able to save your search image to permanently link to your search results. Unregistered users of TinEye cannot save their search images, as they are automatically discarded after 72 hours. Links to these searches will stop working after 72 hours, unless a registered user happens to save the same image. Registered users of TinEye can save their search images if history is enabled in their user Profile. Saved searches are available from the History page, and permanent URL links to any saved search can be bookmarked or shared with friends.
Registration to TinEye is free.
