Understanding Google’s Modus Operandi

No Comments

This post came from Robert Adler (BOFU2U) of AutomatedTendencies.com.Robert has a solid reputation in the internet advertising community.He is known for creative thinking, and his speciality is using the search engine for a vast number of wicked things.When he has free time, he likes to put some of his thoughts without context in various closed chats on Skype because this delights and confuses most of those who chat with him.If I ever had a moment of enlightenment in my way of understanding search; it was right after reading one of those posts and a long night after that in which I started to comprehend it part by part.
Robert began by clarifying the base operation of the search engine omitting the storage of information into five basic functions:

  1. Crawlers
  2. Parsers
  3. Classifiers
  4. Judges
  5. Monitors (I will speak more about these in a later post).


Crawlers may contain many different aspects of their daily routine.Mainly, they’re known for collecting pages and sending them back to their parents for indexing and classification.They’re the first line of soldiers.The militia.The lowest rank of Google’s infrastructure.These are the guys who obtain what needs to be achieved.Simplified to the lowest level, think of these as similar as you think of dog which you tell to fetch a ball, bone, or anything else.Dog’s job is to bring the object and then by chance, brings it back to you.They don’t inspect the object, and they don’t analyse or classify it, they only grab it and return it.


When the crawler collects large chunks of unstructured data from what is now your site/blog post it has to convert it into a format that it is easier to understand for the classifier.When you were in school, a teacher would often suggest or recommend that before writing a paper you write an outline first.This would expand on the structure and topic and deliverance would be a lot better.This, however, is opposite, the paper is the first step, and then you slam it to an outline.However, since these guys aren’t classifying anything or something like that, they’re only making the material which is easier to read and which would speed up the rest of the work process.


Classifiers are there to determine the actual subject of a page.Not just that, but to decide if the link is ‘’related ’’or‘’ relevant to a page it is connected to.This is more than just for the page, but also on the website level, category and also on a tag level rather than just the page of the content itself (will speak more about this later).


Judges, as I like to say, to simplify are at the level after the classifiers that use the previous step and spread the ‘’juice’’ or ‘’scores’’ in accordance with the information that was given to them by the classifiers.This is what decides if a page should receive credit for something, or how it should be evaluated from the links pointing inwards to it.Are the links pointing in old?How old is the page so the credit can be properly distributed to the children it’s linking to.This is all done on the judge level.

Connecting the Dots

Have you ever noticed that Majestic Topical Trust Flow’s topics are as same as DMOZ’s open directory category tree?Have you ever asked yourself why?

If you take a look at top ten results for 50-100 keywords in a particular niche, have you registered a pattern in the topical trust flow?

E.G. The most of top 10 results for TEFL keywords are ARTS/EDUCATION, and REFERENCE/EDUCATION or that fashion subjects are dominated by SHOPPING/CLOTHING?

The longer you look at the data, the clearer it becomes that tools like Majestic are giving you a close up at the effects of the classification/judge parts of Google’s scoring work process (topical page rank).This aids a search engine to establish if some keyword is an appropriate match for some search query.This also lets the search engine to feel whether a sense or a link graph is important below the first and second tier of links by adding a flavour to page rank.Before topic, sensitive page rank was introduced Google was limited by what it would see under the first tier because of CPU run time.Even though search engine still can’t see past level one, now it can sense a spam or a low-quality link profile.

Topical page rank/topical trust flow goes through links like water flows through pipes as the regular page rank does.A clear thematic signal gives the impression to the search engine that a site is an authority in its foundation.So, what’s the focal point?It’s very simple, first find out which classification the search engine thinks to be a perfect match for the sought-after keywords and go for a robust onsite plan supported with links that are relevant, both for topic and theme, making sure your website fits the proper classification.
