What is Google Pagerank?
Pagerank is an SEO term for a scoring system that gives points to each web page in the virtual world which is owned by Google. Points are earned each page will be included in the final assessment for a position on the search page. The larger point is, the greater the "help" given to your position. But keep in mind, that the portion given to pagerank is now not at first. So just because you have a PR3 course you can not beat PR0, if this PR0 excel at other points.
How to Calculate Google Pagerank?
Pagerank formulaPagerank formula The formula for calculating the Google PageRank itself is:
00:15 + PR = 0.85 (PR (T1) / C (T1) + PR (T2) / C (T2) + ... + PR (Tn) / C(Tn))
PR (T1) the value of T1 pagerank page
C (T1), the number of outgoing links from the page T1, apply so from T2 to Tn.
The formula is what will iterated repeatedly until the specified limits Google. The final condition of iteration is what will be the point to your pages.
Case Example Calculation Pagerank
Now we see an example of its application case is a matter between two web pages:
In the above case, both starting with the PR2 (actually we do not know the value of what the PR, but we are assuming equally PR2 value you want to change them both to whatever the result will be the same later, not believe?
The first calculation:
PR Page 1 = 0:15 + 0.85 (2/1) = 1.85
PR Page 2 = 0.15 + 0.85 (1.85/1) = 1.72
We did the second iteration:
PR Page 1 = 0.15 + 0.85 (1.72/1) = 1.61
PR Page 2 = 0.15 + 0.85 (1.61/1) = 1.51
We did the third iteration:
PR Page 1 = 0.15 + 0.85 (1.51/1) = 1.43
PR Page 2 = 0.15 + 0.85 (1.43/1) = 1.21
PR Page 1 = 0.15 + 0.85 (1.21/1) = 1.17
PR Page 2 = 0.15 + 0.85 (1.17/1) = 1.14
PR Page 1 = 0.15 + 0.85 (1.14/1) = 1.11
PR Page 2 = 0.15 + 0.85 (1.11/1) = 1.09
You can see that the figure is closer to PR1, which is why many people believe that the default value of the PR of a page is PR1. That will change it later is how many incoming links and outgoing links from that page.
So let's make the calculation is a little more complex. What if it involves 4 pages, 1 homepage, 1 page article, and 2 pages of other websites. See the picture below:
We give again assuming the initial PR for this, it's up to the fourth page whatever. This time we assume everything is worth PR1. What would happen if all four pages of this assembled as above? Let's see:
The first iteration:
Home page PR = 0:15 + 0.85 (1/3 + 1/1) = 1.28
PR Page Articles = 0.15 + 0.85 (1.28/1) = 1.24
PR Page External 1 = 0.15 + 0.85 (1.24/3) = 0.50
External Page PR 2 = 0.15 + 0.85 (1.24/3) = 0.50
The second iteration with values above:
Home page PR = 0.15 + 0.85 (0.50/1 + 1.24/3) = 0.93
PR Page Articles = 0.15 + 0.85 (0.93/1) = 0.94
PR Page External 1 = 0.15 + 0.85 (0.94/3) = 0.42
External Page PR 2 = 0.15 + 0.85 (0.94/3) = 0.42
After 40 iterations the value to be as below:
Home page PR = 0.64
Article Page PR = 0.69
PR Page External 1 = 0:34
External Page PR 2 = 0:34
General questions about the calculation
General questions about the calculation of pagerankof pagerank What do you see? Do you feel anything strange? Maybe there will be saying: "The total initial PR it is 4x1 = 4, why after iterated total value of less than 4?" You need to note that the value of 1 for each page was just an assumption only. You would love the entry value assumptions whatever, the end result will not be far from this value. All that because of the structure of the links between the fourth page.
Maybe some are asking: "Why is the home page that accepts 2 incoming links and outgoing links only give 1 value is smaller than the page the article is receiving only 1 incoming links but gave 3 outbound links? Does not link out of the yard more articles and links the inclusion of a few? Why PR is larger?"
The answer is simple, for each round of counting, Google PageRank was assessed only from the incoming links rather than outgoing links. But since this is ultimately circular iteration number of links that came out earlier will return affect the value of the input.
To make you understand, then you should see only one iteration cycle. Home value is smaller because despite the inclusion of a link but there are two points, both of them small. Links that go to the homepage comes from one page article is divided into 3 points and 1 external pages that are small points.
Unlike the article page, although the inclusion of only one link, namely from the porch, but there is only one link out of the porch, so the point is not divided. So if you want to increase your Google PageRank of a page, there are three things that must be to consider, namely: Number of backlinks, PR of each backlink, and the number of outgoing links of each backlink.
So just because the incoming links to your homepage more than the incoming links to the articles are not necessarily greater value veranda. Preview the value of the points forwarded by each backlink earlier.
Whether we can also calculate pagerank set by Google? It seems not, we will hit 2 major problems:
- 1. We do not know what the criteria set by Google to stop the iteration.
- 2. We do not know how the circuit schematic entire webpage in this virtual universe.
Trying to calculate the PageRank of your page is a futility, because the increase backlinks it is impossible to prosecute you with your human power. You have to make a robot that explore the entire virtual world. And if you did eventually make a robot like that, might as well make your own search engine.
So simplify it mind you. Simply find backlinks that much and if it's all one way dofollow backlinks, then there would be no problem for you. Only one way it means other people's blogs pointing to your blog, and your blog is not pointing back to the blog man.
Regarding Additional Knowledge Pagerank
Is the image links also continue pagerank?
If you mean like a banner then the answer is YES! Just do not let you "sell" banner that continue pagerank. If the Google algorithm captures this, then you are slammed pagerank. Such events experienced one foreign news agency, which originally pageranknya 7 but later given sanction to 3.
How do I increase pagerank?
Simple as to increase pagerank you need is to get backlinks to your blog. While searching backlinks is part of of the SEO optimization Offpage that will greatly affect your blog's ranking in the SERP.
Why is increasingly difficult to rise to a higher pagerank?
You've seen the last iteration, the higher the PR that you're after, the more pages that are involved, and the more evenly pagerank making it increasingly difficult to climb. If you want to know to rise from PR0 to PR1 maybe 100 backlinks is enough, but to rise from PR9 to PR10 backlinks you need additional billions. Perhaps the illustration below you can realize how difficult it.
Can you see? Increasingly steep ladder, and the struggle for PR7 yet nothing compared to you want to go up to PR8 to PR10. You really have to have something to offer to the rest of the world to penetrate PR8.
Is pagerank of backlinks only do we need to pay attention to?
The answer is NO! Of backlinks that are assessed not only points aka link juice page, there are at least 4 major points assessed from a backlink:
- Points are given pages.
- Voting anchor text that it provides.
- Article points to the relevance between your article.
- Points reputation of the web page domain.
The best way to maintain the stability of PageRank
Stability pagerank happen if put it relatively stable. For example, if you rely on the article page as a source pagerank homepage, then make sure there are no outbound link on the homepage, because it will reduce the points page article. To do this use the rel nofollow, and you should not change so nofollow dofollow blogs.
