Google PageRank - what is it?

Site PR is...

PageRank (PR) is a site evaluation criterion used by the Google search engine. This indicator indicates the credibility of the Internet resource from the point of view of Google. The main difference between PageRank and the TCI is that this indicator is calculated separately for each page of an Internet project. When forming the value, internal linking is taken into account, as well as links leading from other sites.

The PR score is related to the number of links leading to the site. To increase PageRank, you can place paid links, register in "white" directories, exchange hyperlinks with similar web projects. An effective method is considered to be articles containing a link to the site being promoted.

How to check the PR of a site - installing an informer

If you wish, you can install a special counter button on the pages of your web project. This will allow you to check the pagerank of a site by simply visiting your site. You can get the informer code at this link http://mainspy.ru/schetchik_tic. The counter will allow not only to check the site's PR, but also to demonstrate this indicator to visitors (including potential advertisers).

Website PR - what is it? Find out with the help of specialized services

There are special online services that allow you to determine PageRank. To check the PR, you can go to http://www.cy-pr.com/. This service provides a large amount of information about the Internet resource:

• expiration of the domain registration;
• hosting, server IP address;
• download speed;
• page encoding;
• visibility in search engines, etc.

If you use the Firefox or Internet Exlplorer browser, then checking PR pages can be done using the special Google Toolbar application.

Bulk PR check is performed by the service http://www.raskruty.ru/tools/cypr/. Each domain name must be entered in a special form on a new line. With the help of this tool, a mass check of the PR of up to 100 sites is carried out.

How to find out PageRank using programs

A very handy tool for SEO analysis is the free Site Auditor program. It allows you to find out PR, as well as check the position of an Internet resource in search engines. In addition, the webmaster will be able to set how many pages of the site are indexed by search engines. You need to enter a domain name in the http:// field to determine the PR of the site, the check is carried out within a few seconds.

How to check page PR

If you need to set the PageRank of a single document, you can use the http://xseo.in/ipr service. This system makes it possible to check up to 35 documents in one session. In addition, you can add an RDS bar module to your browser, designed for complex SEO analysis. In addition to PageRank, this module determines the site's CMS, the approximate number of incoming links, and many other indicators.

Greetings, dear readers of the blog site. Today we will continue to consider the main indicators of the success of promoting your site and focus on the concept of Google PageRank or PR for short. we talked about in this article

Today we will consider in detail all the same issues, but in relation to the PageRank indicator.

The Importance of Google and its PageRank for a Runet Webmaster

Therefore, in order to achieve good attendance in Runet, you will have to serve two gentlemen and try not to lose face in front of either of them (do not fall under pessimization or even worse - a ban).

Remarkably, often at the initial stage of development traffic from google may be significantly higher. Perhaps this is due to the fact that he is more loyal and not biased towards young projects, and especially blogs..

The PR indicator has an insignificant impact on the position of the document from your project in the search results. True, it is not the main criterion for determining the position, but ceteris paribus, its higher value will allow the page (document from your project) to stand above the document of similar relevance, but with a lower rank.

Relevance meant the correspondence of a particular page to the query entered by the user in the search line (). In a nutshell, the relevance of a page to a search query is determined by the presence of words in the TITLE (title) of the document, in the headings of articles, in STRONG and EM tags, etc. Read more about this at the link provided, and I also advise you to familiarize yourself with.

Role of PR will be especially important when ranking pages for a one-word query (when the user enters only one word in the search bar). In this case, it turns out that a lot of documents will be relevant to this query. It is in this case that our hero will play a key role in determining the positions for these documents that are identical in terms of relevance (corresponding to the entered query).

The PageRank indicator was invented by the founders of the campaign (Sergey Brin and Larry Page), who then successfully applied it in their currently most popular search engine in the world. The merit of this puzomerka in their success is undeniable. Let's now take a closer look at what PR is, how you can increase it, how to measure it, and how to set a counter that displays its current value.

Its main difference from the Yandex TIC is that it is calculated for each page of the site (document) separately. But the same scheme for assessing authority from the scientific world is taken as a basis, when the rank of an author depends on the quantity and quality of references to him from the scientific works of other authors.

The more indications and the better they are (the indication can be given by a student in his term paper or by a professor with more weight in the scientific world), the more authority this work of this author will receive.

Those. the main criterion in calculating PageRank, as well as in calculating the TIC, are links to the pages of the site. But unlike Yandex's puzomerka, it is not the authority of the author of scientific works (the entire resource) that is evaluated here, but the authority of individual scientific works of this author (website pages or, in other words, documents). True, Yandex has a similar puzomerka (VIC), but it is little known, because no one will ever be able to even approximately estimate its value.

It is true, because different works of the same author can differ significantly in the quality of execution and the relevance of the information provided in them. It is thanks to this selectivity that it becomes possible to use this puzomerka for ranking documents in search results, if they turn out to be equally significant in terms of the main relevance indicators.

Page ranking in Google search results, it can be simplified as follows:

1. First, the machine finds in its main index (there is also a snotty index that is not searched) all documents in which the words from the user's query occur
2. Then, among them, those are selected where the density of keywords is higher (from the user's request) in the text of the document, in its TITLE heading, in accent tags (H1 -H6, STRONG, EM), etc.
3. Also leading from other projects to these documents. This text also analyzes the density of keywords from the user's query. This thing is called link ranking.
4. Well, in the end, the results obtained can be slightly adjusted taking into account the Page Rank indicator. As a result, documents with the same relevance for this query will be placed in their places in the search results. Yandex also uses its VIC (weighted citation index) to adjust its search results

What is PR, how it is measured and how it is formed

In fact, it is a kind of measure (criterion of value) of a particular page on the Internet. Its value depends on the number and quality of backlinks leading from other pages to this document. The more links, the higher the PR value will be.

But what is also very important is the value of the static weight of the page from which the link to the document leads. The fact is that a part of the PageRank value of the donor page is transmitted by link.

But that's not all. The fact is that if there are several links from the donor page (one of which is to our document), then the transferred static weight will be divided equally between all these links.

The amount of PR that a page can link to is much less than its own value (it used to be 85 percent, but now it is less than 10 percent, according to observations). This amount of statweight will be divided between the documents to which it refers.

The ideal case would be if a page with a Page Rank equal to 10 (the maximum value) links to your document, . And it would be really cool if she was the only one.

In this case, a gigantic weight will be transferred to your document, sufficient, probably, for your page's PR to rise to 9. If, however, several more links (including yours) are put down from this ideal donor, then the weight transferred for each of them will already be divided for the total number and the nine you will no longer receive. It's a shame, right? And so I wanted to.

Yes, I almost forgot to tell you about how and in what way the PageRank value is measured, as well as about how to prohibit the transfer of vote (weight) via a link leading from the pages of your project. First, about the units of measurement. There are two scales and, accordingly, two values.

The first of the presentation options expresses it as a real number and has a linear change. Those. an increase in this value will be proportional to an increase in the amount of static weight transferred to this document through links from other Internet resources. This number is updated almost in real time and is constantly taken into account when ranking.

The second version of the PR representation is derived from the first. This value is called toolbar value and has a range of change from 0 to 10 (a total of eleven possible options). The toolbar digit is obtained from a real number according to a law close to logarithmic (strongly non-linear):

Real number denoting real stat weight	Toolbar number resulting from
from 0.00000001 to 5	1
from 6 to 25	2
from 26 to 125	3
from 126 to 625	4
from 626 to 3125	5
from 3126 to 15625	6
from 15626 to 78125	7
from 78126 to 390625	8
from 390626 to 1953125	9
from 1953126 to infinity	10

The toolbar number is not updated often - once every few months. Its zero value is usually assigned to new resources or projects that have fallen under the ban of Google, and only a few colossi all over the Internet have a value of 10.

As you can see from the table above, at first it doesn’t take many links with good weight to increase Page Rank, but with each new number, its further increase becomes more and more difficult, and often impossible task.

On average, well-optimized (both internally and externally) resources have a PR of the main page equal to 4 or 5, and some even achieve six, but further growth in this indicator is available only to very serious and global projects.

So, the limit of our dreams and possibilities is most likely 6, and even that is unlikely. You say that I'm a pessimist?! No, I'm more of a realist. But if you suddenly get (or have already received) a Page Rank equal to 7, then please unsubscribe about it in the comments (and be sure to put a link to https: // site so that everything will be fine with me too).

Prohibit the transfer of static weight through external links

In principle, this is not at all difficult to do. Google made sure that it was possible not to vote on another resource. To do this, it will be enough to add an attribute to the link tag A (I already provided a link to an article a little higher, where everything is chewed in detail). For example like this:

Everything about creating websites, blogs, forums, online stores, their promotion in search engines and making money on the site

After that, the status weight from the donor will not be transferred to the acceptor (the document to which the link leads). Why might you need to prohibit weight transfer? Everything is pretty simple here. You just need to remember that PR can be transmitted not only through links leading to other projects, but also through links leading to internal pages of your own resource.

Now imagine a situation where you have ten internal and ten external links in one document. There are twenty in total. The static weight transferred for each of them will be equal to one twentieth of the maximum possible that this document (donor) is able to give. Therefore, the acceptors will receive one-twentieth of the maximum possible weight (pagerank).

Now imagine that you have added the attribute to all external links, thereby forbidding the transfer of weight over them. As a result, all the weight that the donor is able to give will be distributed among ten internal links. For each of them, one tenth of the maximum possible weight will be transferred, which is twice as much as in the case without using the attribute.

So you prevent leakage PageRank from your project, accumulating it inside and increasing your own puzomerki. As a result, these pages of your resource, all other things being equal, will be able to take a higher place in Google search results due to the saved rank.

P.S. There is an opinion that now Google has somewhat changed the action of the attribute and your internal documents in the above example will still receive one-twentieth of the weight, and everything else will leak to no one knows where. Debatable, but...

However, I still mandatory prescribe in tags A, and other elements. Yes, and with paid placement of guards through the GGL, RotaPost, GetGoodLinks, Miralinks or WebArtex exchanges, the main requirement is often the minimum number of links through which the weight is transferred.

What can lead to an increase (decrease) in PR

The weight transferred via the backlink depends on the PR value of the donor document and the total number of outgoing links from it. Pay attention, I spoke not only about external, but also about internal links. Thanks to this wonderful opportunity and competent internal linking, you will be able to raise the PayRank for most documents of your project, even without using external links generally.

When calculating PageRank, all external and internal backlinks will be taken into account, except for those that lead from banned sites. Those. your ill-wishers will not be able to make your site disgusting by putting links to it from the pages of banned websites (after the introduction of the Penguin algorithm in Google, this statement can be considered controversial). But if you yourself post backlinks to banned projects (or just to outright GS), then you may suffer a sad fate.

The static weight of your documents may decrease if some of the leading links to them suddenly disappear or the Page Rank of some of them decreases. Despite the fact that the stat weight affects the position of documents in the Google search results, a high PR value does not guarantee a high position in the SERP. Otherwise, for any query entered, only super trusts with PRs of 10 and 9 would have ranked first in Google search results.

Identical links from one page will be counted by Google as one, and links from a web page to itself are not taken into account at all when calculating PageRank (you cannot vote for yourself). By the way, it is not a fact that the main one will have the highest stat weight among all the others. There may be internal pages equal or even superior to the main page in Rank.

It should be borne in mind that the Google search robot is rather inert and does not take into account all backlinks instantly. It may take time (up to several months) to fully account for them.

Where and how you can see the Page Rank of any site

In the form provided, you can enter one or more URLs, and then click on the "Check PR" button:

This method allows you to conduct a mass check of PayRank for a large number of projects at once. However, in most cases, the best option is to install SEO extensions for the browsers you use. In this case, the PageRank value for the page opened in the browser will be displayed on its panel.

For the Opera browser, there is, as well as:

Counter options for displaying PR

There are several options for counters that display PayDrunk for the document on which they are installed. True, there are options that show the PR only of the main page, because it is, as a rule, the highest and should make a greater impression, for example, on advertisers. You can see an example of such a counter.

You can get the code of a similar informer. In the window that opens, you will need to enter the main URL in the "Site URL" field (in this case, its value will be displayed on the created counter):

Click on the "Submit" button, and then select the desired design of the informer. As a result, an area with the resulting code will appear:

You will only have to insert it in the right place of your site template or in the text of some page (for example, intended for advertisers).

Choose the appearance of the informer and copy its code to the area located to the right of the counter picture. You will need to insert this code into your project template, as a result of which it will show visitors the PR of the open page. For example, like this:

As a guide to inserting code into a template, you can use the tips for inserting attendance counters into a Joomla, WordPress and SMF template - and .

How to check PR for all pages of your or someone else's site

It often happens that you need to find out the Page Rank indicator for all documents available on the project. Doing this individually can be very time consuming. It is for these cases that quite convenient services have been created.

Also, to understand how the Google search engine treats you, it will be useful to know how many of your documents are in its main index, and how many fell into the additional one, which is often called the snotty index (Supplemental Index). Why is it so important to know this? Well, it's pretty simple here. The search is conducted only on documents located in the main index.

Pages of sites located in the additional index (Supplemental Index) are not included in the search, except in very rare cases. Therefore, in terms of attracting visitors, they are completely useless ballast.

Of course, you don’t need to get rid of them, but it will be useful to know their number. Read more about all this in the article "".

The thematic citation index (TCI) of Yandex determines the "authority" of Internet resources, taking into account the qualitative characteristics of links to them from other sites. This qualitative characteristic is called the "weight" of the link. It is calculated according to a specially developed algorithm. The thematic proximity of the resource and the sites referring to it plays an important role. By itself, the number of links to a resource also affects the value of its TCI, but the TCI is determined not by the number of links, but by the sum of their weights.

The TIC can be measured for all resources referenced by any of the resources indexed by Yandex at least once.

When calculating the site's TCI, links from bulletin boards, forums, blogs, online conferences, unmoderated directories and other resources to which anyone can add links without control by the resource owner are not taken into account. Also, when calculating the TCI, links from sites located on free hostings are not taken into account, if they are not described in Yandex.Catalog. In other words, all such links have zero weight.

The citation indices of the so-called mirrors (aliases) are combined, that is, the weights of all non-repeating references to mirror addresses are summed to calculate the TCI of the main address. The main address is determined automatically and matches the address indexed by the search engine. You can change it with the Host directive.

Google PageRank

PageRank is a numerical value that characterizes the "importance" of a web page. The more links to a page, the more "important" it is. In addition, the "weight" of page A is determined by the weight of the link transmitted by page B. Thus, PageRank is a method of calculating the weight of a page by calculating the importance of links to it.

Classic PageRank View Model

The basic formula describing PR is as follows:

where d — damping factor, reflecting how much weight the donor page can transfer to the acceptor page. Usually it is taken equal to 0.85, which means that the page can transfer 85% of the weight (shared among all acceptors referred to by the donor). In other sources d is the probability with which the user will go to one of the acceptors, and not close the browser, which is basically the same. What is the numerical value of this parameter in Google they know only there, the rest will take it equal to 0.85 (apparently from the experimental data);
n — number of pages, linking to the acceptor page (which are not filtered);
T i- i-th referring page;
C — number of external links on the donor page.

PageRank Toolbar View

Since there can be many referring pages, and the total number of pages in the Google search engine is quite large (about a dozen billion pieces) and their number is constantly growing, it would be very wrong for webmasters to present page weight in absolute values. For this, the concept TLPR — Toolbar PageRank, which has a value from 0 to 10 (green scale in the Google Toolbar).

To fit all page weights between values ​​from 0 to 10 use logarithmic scale:

TLPR = Log base (PR) * a

where base- the base of the logarithm, which depends on the number of pages in the search engine (and possibly on a number of other factors). Some take it to be 7;
a is a reduction factor that satisfies the inequality 0< a ≤ 1. Оптимизаторам его можно принять равным единице для упрощения расчетов.

It is wrong to conclude from the above that zero TLPR means zero real PageRank. It can be seen from the first formula that even if n=0, we get the minimum PR min = (1-d) = 0.15. This value corresponds to TLPR ≈ -1. With such (negative) values ​​of the toolbar PR, it is considered that PR = N/A (or not yet determined), but it also affects the distribution of weight between acceptor links. It should also be noted that the toolbar value is intended only for displaying to webmasters in the Google Toolbar and does not affect the search results in the sickle. The real PR of the page influences the issuance in the sickle!

The real PageRank service will try to detect your site's future PR based on the quality and quantity of backlinks. Notice Expected PageRank can only be considered as a guess. The future Google PageRank of a site generated by our service may not be accurate.

It can be said that it is not PageRank Prediction, this is to a greater extent the definition of real PR. It's no secret that Google usually assigns less PR than it should be. The reasons vary, from selling links to a young site to minor Google policy violations that you may not be aware of.
Therefore, usually the real Page Rank should be higher than what you see on the Google toolbar. Our service determining real PageRank will show you what your PR should be if you remove all Google down factors.

A free comprehensive SEO audit service has been opened on our website, which calculates, among other things, the Real PR described here.
As a result, in the course of determining the real pagerank, you will be directed to the page of the result of a comprehensive analysis of the site being checked, which contains, among other things, the calculated values ​​of the Real PR.

Keep in mind, results from www. and without www. may differ significantly.
Attention, the results of the check are stored in the database. You can track changes in real PR over the past period on historical PageRank forecast charts.

The PageRank forecast service tries to predict the PR of a resource, what it could be with the next PageRank update. The Real PR tool performs complex calculations and comprehensive analysis to determine the future Google PageRank of a site.

We calculate the value of the predicted PageRank, but do not round it up, as Google does. Therefore, the real PR values ​​vary from 0.00 to 10.00, i.е. thousand-point scale.

Not so long ago, another *up* Google PageRank (PR) indicator passed. "How to check all pages of a large site for PR?". Since most online services allow you to check only 50 pages, which is too inconvenient when a website has hundreds or thousands of pages.

Fortunately, there are many different sites where it is possible to check the Google PageRank of a site and pages. Scripts that check the PR of the site, for the most part, allow you to find out the PR of only the main page. But the PR indicator is assigned not only to the main page, but also to each individual page, in addition, the PR of internal pages may be higher than that of the main one.

This may be due to a large number of backlinks and quality external links leading to the page. Usually, this is explained by the fact that individual pages are more often referred to when finding interesting material on them.

I was very surprised that many popular website analytics services do not have such a very useful feature. As for me, it would be a great addition to Google's webmaster tools.

Since the site map is loaded there, and for each page it would be possible to display its PR. Moreover, there is more trust in tools from Google than from third-party developers. Therefore, you often have to use several services to determine the veracity of the results.

You can use the program for mass checking the pr of the inner pages of PaRaMeter. The PaRaMeter program saves the results of all checks and then you can compare how PageRank has changed for the pages of your web resource.

In search of SEO tools, I came across a rather interesting SlavSSoft service, which allows you to massively determine the PR of the site's internal pages. To prevent server overload, there is a limit of a maximum of 500 pages - although I think this is quite enough for an average site.

In addition, the definition of PR does not occur when scanning pages, but according to the sitemap Sitemap, the address of which must be added to an empty line on the script page. If you do not have a Sitemap file, you can use other tools to determine the Google PR of internal pages, right there on the site.

After adding the address of the Sitemap file, the SEO analyzer will show the full list of pages in this file and start checking the PR of each of them. For SEO optimizers, this resource will be quite useful, especially for webmasters selling links on SAPE exchanges.

It will give you the opportunity to determine in advance the price of links from internal pages, and also control changes in PR, as a result of work on external optimization. In addition to mass checking PR, SEO service can analyze internal and external links, find out PR by data centers, and so on.

Here is a list of 2 such sites for checking the PR of the main page and internal pages of the site with a brief description of their work:

xseo.in - Checking PageRank is carried out one level deep from the given page. It is also possible to check the PR of all pages to be inserted
list. There are also a large number of useful and interesting services to check.

my-seotools.ru - The definition of PR does not occur when scanning pages, but according to the Sitemap site map, the address of which will need to be added to the empty line on
script page - I really liked this service. Displays in an attractive table near each url its PageRank, at the end of the table sums up the number of internal pages with different PR.

The only inconvenient thing is that the check goes on the first 100 pages, but if you register there, then 300 pages are available for checking for free or more but for a fee. The prices are not very high, but I personally don’t see the point in paying for such data.

If you do not need to check all the internal pages of the site, but only some of them - there are tools for checking Google PR of several pages at once, in one batch (by entering the address of each page manually). In addition, it is possible to check the PR of the main page for all Google data centers.

With the current trend towards closing all external links with the “noindex” and “nofollow” attributes, I advise you to use a tool to analyze the quality of closing of all links, including internal ones. It will not be superfluous to relink the internal pages of your website with contextual links. I recommend doing this, because it gives a greater effect compared to the output of similar news and has a great impact on increasing the Google PageRank of the site's pages.
