PageRank is an algorithm used by the Google search engine to measure the authority of a webpage. While the details of PageRank are proprietary, it is generally believed that the number and importance of inbound links to that page are a significant factor.
PageRank was the original concept behind the creation of Google. Given this line of thinking, a link to a site is similar to a citation in that it implies authority. It's key to understand that nobody really knows what goes into PageRank. Many believe that there are dozens if not hundreds of factors, but that the roots go back to the original concept of linking.
If you have been working in the industry for more than a few years, you will undoubtedly remember the excitement that came when you heard that there had been an update to the PageRank toolbar. With any luck, your recent efforts would have delivered an increase in your PageRank score, knowing that this meant that Google was now viewing your site as more authoritative than it previously was. An increase in your PageRank score was a great demonstrator that your SEO strategy and, in particular, your link building strategy was working.
But that is not because it is no longer important, just that it is no longer a public-facing metric. And when SEOs can no longer measure something, they eventually stop talking about it.
In this guide, we will dive deep into everything you need to know about Google PageRank, and its importance in This is what we all came to associate with PageRank and the metric that SEOs became universally obsessed with. And what it is important to understand is that PageRank is all about links.
We can simplify the PageRank algorithm to describe it as a way for the importance of a webpage to be measured by analyzing the quantity and quality of the links that point to it.
Perhaps unsurprisingly, PageRank is a complex algorithm that assigns a score of importance to a page on the web. But as far as the everyday SEO was concerned, PageRank was a linear representation of a logarithmic scale of between 0 and 10 that was displayed on the PageRank toolbar.
A PageRank score of 0 is typically a low-quality website, whereas, on the other hand, a score of 10 would represent only the most authoritative sites on the web. The key to understanding PageRank scores is that it uses a logarithmic scale. Not sure what that means in layman's terms? A logarithmic scale is a way of displaying numerical data over a very wide range of values in a compact way—typically the largest numbers in the data are hundreds or even thousands of times larger than the smallest numbers.
As reported by Search Engine Watch , "It has an estimated base of The reason why SEOs became so fixated on this metric is that PageRank passes from one page to another, meaning that a website can gain authority by being linked to from another that has a higher PageRank score. Quite simply, PageRank that is passed between websites by links helps a website to rank higher, and the algorithm is based around the concept that a page is deemed to be important if other important pages link to it.
Google still uses PageRank as part of its algorithm today, but the original patent has expired and, in this original form, hasn't actually been used since , and the one that we now see is ultimately far more complex.
The first PageRank patent was filed on September 1, , and became the original algorithm that Google used to calculate the importance of a web page and rank these. In short, Google was literally formed based upon Sergey Brin's idea that information on the web could be ranked based upon a page's link popularity, that the more links point to a page, the higher it ranks.
And if we take a look at the paper that introduced Google , we can clearly see PageRank referenced when explaining the search engine's features:. The Google search engine has two important features that help it produce high precision results. First, it makes use of the link structure of the Web to calculate a quality ranking for each web page. This ranking is called PageRank and is described in detail in [Page 98]. Second, Google utilizes link to improve search results. The paper goes on to explain that, "The citation link graph of the web is an important resource that has largely gone unused in existing web search engines.
In , Google introduced the toolbar that we all now come to remember as the way in which we could see our site's and our competitors' PageRank score. As a result of this, SEOs began to become fixated solely on increasing PageRank as a metric for improving rankings, driven largely by a simplified understanding of the algorithm that suggested that a web page with the highest number of links should rank the highest.
The recent wiped out of fraud websites really did some good to the internet. It made the internet a cleaner place for the hardworking and honest to goodness people running blogs, and websites. Thanks for visiting my blog and leaving a nice comment.
This was interesting information to learn. Thanks so much! I think this info is good for people who want to be technical. Businesses that are striving to place on top pages. Other than that, blogging for fun doesn't need good page rank. If you like, email me directly and we can converse. Two things to take away from for sure are: 1 traffic - 2 content - the more your content affects people the more they are valued.
Other items take a bit more pages to explain. Thanks for your great comment. Hi, because of the great demands, I've written a more detailed, key requirements in Part II. Google Pagerank Part II. I'm a bit late, but thanks for the tips. I was surprised to learn that I only have a ranking of 2 when I'm on page one for most relevant searches, and many times I'm no. Wish I understood why my ranking is so low? Any ideas? Jacquie, I was going to ask you which pages ranked you 1?
Because Ranking 1 is not good with Google. Please see above the 1,2,3, etc. Google as stated has a formula to which they use to rate sites, so as commented previous, your "content" has tremendous impact on how your site will be ranked. I couldn't check you site, since your link didn't work for me today.
So if you take a look at the sites with the higher ranks above for example- Government site, the information on this site affects everyone I am not saying that you need this type of info on your site but just wanted to point out the mindset Google has, and analyze your contents to make your comparison for better understanding how they've ranked other sites and see if that helps.
But remember, Google isn't the only ranking system out there - but they are very powerful. PR is a mystery to me. I have two blogs and both are PR 3. Hi Len, thanks for linking to my article. To answer your question honestly, the equation certainly doesn't work out for some sites. The -now three- secrets that most of us agreed on is the combo of: 1 traffic, 2 quality of content 3 number of quality links - for example linking your site to a PR rank of 3 which is my site will increase your chances of being rated higher quicker, of course you will need many more than just one quality link.
Hope this helps, there are other ingredients which we have clues about - but they do not always match-up to the sites. Thanks for the expklanation, I added it to wikipedia in Dutch. I wondered why I got a PR5 on my site www. Wonderful, a PR 5 is so awesome, congrats. And thank you Kees for adding my post to Wikipedia Dutch. But u say most of the websites fall in this zone :. Good luck to all of us.
PR high or low depending on what you're in blogging for. PR isn't the only thing Advertisers look for and it isn't the most important element for all the bloggers. I hope you have your goals sorted out, smiles. Excellent article, now i know what those page rank stand for, or at least have an idea where a website is if a check o that website page rank.
I'm not a SEO expert but this information really help me in understanding those page rank. What about Traffic Rank any information on this item? I wish I knew what to do to get my PR above 0 after 5 months of blogging original content. Thanks for the good description of the PR scale. Then I ran across a Google page, quite by accident, that stated that if you are a 0, that your blog is not "indexed", which basically means it is not registered by Google.
I don't know if registered is the right word -- it's not recognized by Google yet, bc it has not been catalogued into their list of blogs yet. This article by Google went on to say that, if you were reading this article, and you were still a 0, that they may have just not had time to get to your blog yet, to review that it was a legimate blog, and to add it to their list of blogs, so that they could index it catalogue it , add it to the list of blogs they would continue to give PR ratings to, decide to move up and down in their Google search engine esp if you "pinged" your blog , etc.
Blogger Broadcast. It was actually blocked and deemed not appropriate due to reasons given by a generic email from Google. A zero is however the lowest rank I agree that a zero could also mean that your site has not been crawled by the robots.
And that you could use the webmaster tools from the Google support forum to get your site crawled immedidately. Thank you for finally giving me the answer to a question even wikipedia and other "highly ranked" blogs could not without going into a confusing diatribe about probability formulas and what not Thanks for such a nice comment. I try to keep it simple and straight forward as I would want to know answers that I can understand myself. PR drives me crazy. When I was new in blogging I was very conscious of it.
I can't even sleep or I dreamed about it. Now, I don't really care. It will always be a mystery to me. You are welcome, I hope it has helped you with your blog and what your goals are for it. Best, Amanda. Starting a site and getting listed is very simple if you stick by the rules But it teached me a lot during the time of working out the reasons why, so for that, I am thankful I learned a great lesson, that can only come from experience.
I was wondering what page rank is and when i looked in other site i couldnt understand them. Now what do i do with it lets say if im 5? If you're a 5, and you are monetizing your blog, then PR 5 will give you a lot of leverage with advertisers. So try to get to atleast a 3 and you will see the interest come. Make sure your contact info is easy to get to. Perhaps post it in more than one place. Techsute Answered on your blog. Download the Google tool bar link from the article and your page rank will show up.
You can then type in another one of your blog URLs in afterwards, if you like, to find the ranking of each of your blogs. I prefer this method, esp since I don't always prefer to have a lot of gadgets on my blog s. Another reason a blogger may not want the Google PR gadget on their blog is that if it reflects a score that is not particularly high say a score of 3 or below , then it could reflect poorly on the blog and the blogger. I was told that if one really, really wanted to put this gadget on their blog, to only do it if their blog if they had a PR rating of say 5 or more, not for the purpose of just checking their PR rating.
I thought that made sense to me. Plus i don't like a lot of gadgets on my blog! Thanks for your comments Krissy and appreciate the additional input as well. I do know about the PR checker site. I have it on my other blog. The Google bar is quick for scanning blogs and websites you might like to do business with rahter than having to enter their links in PR checker.
Both tools are great resources, and again, glad you mentioned it. I now have a PR2 after a year of playing about what have i learned it takes time and you cant rush getting a high page rank now to go for a 3 cant be impossible. Yes, it does take time to build the Page rank. Yet, someone always find ways to make things easy to make money.
I am sure you can buy back-links to boost your page-rank but it is not the same. I thought the post will be about the real meaning of the numbers at the eyes of Google. Nice work. Hi, Very good and most needed information. Appreciate u for sharing such valuable information. Thank you. Hi back to you. Thank you for your comment. A more detailed article on the key requirements to improving your page rank. I've been able to earn some money with a PR3.
If you're really speaking of an income, I would bet you will need a few PR5 websites. Very informative article thank you for sharing! This is going to help on my page rank 3 website!! Thank you! I love hearing positive encouragement, I also wish you well of obtaining the PR that you want. Best Amanda. You are welcome. It isn't easy, but keep it up and sooner or later you will achieve what you want.
Looks like you have the content to. I would like to see you achieve your goal too. Good luck. Best wishes, Amanda. The page ranks interpretation is just a comparison of the scale and level we are dealing with everyday. Glad it made sense to you. Nice article. I dont agree with your opinion on page rank 2.
Rather, we measure what others on the web feel is important enough to deserve a link. And because Google does not accept payment for placement within our results, the information you see when you conduct a search is based on totally objective criteria.
How pages are ranked is, of course, of keen interest to SEOs. For many, the original reason of linking has been lost out of the desire to simply do whatever they believe Google might like.
That score, while a great resource for surfers, has also provided one of the few windows into how Google ranks web pages. Some webmasters, desperate to get inside Google, keep flying into that window like confused birds, smacking their heads and losing their orientation…. Enough, please, enough. Forget the Google Toolbar meter. Just forget Google, when it comes to link building. Get a link to your pages from an high PR page and yes, some of that PageRank importance is transmitted to your page.
All those pages are going to send tons and tons of PageRank your way! But important for what? They all link to you like this:. The importance of the links is less, true. But they do have some importance. They carry some weight. Plus, what they say — the relevancy of the words — is key. Search for something, then see if anything below the top ranked page has a PageRank score higher than the top listing. If so and it is so , that shows PageRank is not the most important factor.
See how the search results have PageRank meters in them? See how Movies. The page with a lower PageRank still got the higher search rank! Like seeing these scores in your results? Seem odd? It makes sense and underscores my key point. PageRank is one of many, many factors used to produce search rankings. It lists them in order of importance for what you searched on.
