What is PR?
Let us imagine that the boss gave you the task to pick up the literature, pull the given info from there (and say about the food industry) and prepare this report for the head … such that he could read your prepared report looking smart and very knowledgeable about this topic.
Your actions ?
There are two options:
1. to collect magazines and books and read all night and in the morning without understanding anything to fly out of work or the boss screwed up reading your report – that not chickens but roosters are rushing.
2. collect magazines and books, spit on everything and contact the experts … and here is the most interesting.
You have for example 10 magazines.
You go to the student of the 1st year of the bird institute and ask to indicate which one journal is better to choose for reading. So, as a student – hens saw only in the soup, then his authority in this matter is small … we put him a PR = 1. He certainly does not consider himself so. But you can check it easily. We will ask 10 associate professors about a student and they will say that he is an oak tree (there are no references to students from associate professors) … but if we ask 10 students about the authority of our student .. then those .. same oaks will say yes (10 links with PR = 1 per student) … he is clever. But even here you can ask associate professors about these 10 students and associate professors who say that the students are stupid and sit without a scholarship and do not even see chickens in the soup (no links). After giving all 11 students 10 rubles for a tram and in return, having received 11 autographs (references) from them, you start to go further.
Conclusion: if a student advises you to read 5 magazines out of 10 then you should not believe him as you understand. But let’s not humiliate our student .. all the same, he correctly pointed out the journals on the farming and not on horse breeding.
Then we go to the associate professor (he has PR = 3). He was referred to as a specialist by 100 oak students (100 links with PR = 1).
Now it’s clear … where does the associate professor get PR = 3. This assistant professor advised you to read 3 journals. By giving him a box of beer and a kilo of sprat, you receive an autograph in gratitude from him (link), but that doesn’t suit you either (time is short). Then you go to a professor who has PR = 5. He pointed to 100 students with PR -1 and 20 associate professors with PR = 3. This professional advised you to read one magazine and you can trust him, but even that does not suit you … you are already in the thrill. Nevertheless, giving him your old motorcycle – in return, you will receive an autograph (link) Then you follow the advice to the academician with PR = 7. It was indicated by 100 students, 20 associate professors and 10 professors. Academician advised to read from the journal only one chapter in 5 sheets and he certainly can be trusted, but you are already too lazy to read. And anyway, driving him to a restaurant and paying him a taxi you get from his PR link = 7. Next, on a tip from this academician, you go to the Nobel laureate for cloning chickens and his PR = 9. It was referred to by 100 students, 20 associate professors and 10 professors and 5 academicians. This laureate showed you two sentences and said .. that if you read them from the end to the front … then you’ll open the chicken kingdom. Finally, buying him a Swiss gold watch as a gift and receiving an autograph from him in return (link to yourself) – you went to unscrew two sentences inside out. In the morning – bringing this abracadabra to your boss .. happily whisper to him about some kind of near indicated. The chef, and so preoccupied with his mistress, with distrust reads your creation and understands – he has nothing to do to him at the conference and sends you there. You boldly enter the Palace of Science and climb onto the podium with your report. After reading two magical sentences – hear in response the gloomy silence of the hall. Do not be afraid … the hall filled with academics, professors, associate professors and students feverishly checks links to you … you should trust you. Having found all the above links on you – the hall gives you PR = 10 and a storm of applause, flowers are accompanied by carrying you in the hands of academicians to the banquet hall. You are on Google for the request “kuverdstvo” first.
Of course, all this is analogy.
The bottom line is that it’s enough to have 2 links with PR 7 to your own, to replace for example 1000 links with PR = 1 or 500 with PR 3 or 50 with PR = 4 …. and so on.
That is what its practical necessity is.
p.s All figures are “from the ceiling” and are given only for clarity and understanding of the essence of PR.
