5 Facts You Need To Know About Google Algorithm

Every one, and I mean every one of the netizen have at least once would have surely used Google to search for something over the internet. But have you ever wondered how the Google works and gives you millions of results within nano-second to your search query?Here is the simple answer:

It uses a special method called Algorithms to look for the information that the user has asked for, from millions of web pages over the internet. These algorithms are named after Google co-founders Larry Page and Sergey Brin.The mechanics of these Algorithms are as classified as any Government file, kept within the Google researchers and developers. Here, we are listing 5 important facts about Google algorithms that most of the people would be unaware of:

1. Searching, Crawling, Indexing and Displaying Web page results:

• The web contains over 30 trillion individual web pages, which are rapidly growing day by day. Google navigate the web by following links jumping from one web page to another. This is known as Crawling.
• Google then categorizes the web pages based on the content and site quality, and indexes that page. It indexes about 100 million GB of information for a single search.
• Then it uses “String Theory”, based on which it writes programs and formulas to sort out the best result possible from those indexed pages. During indexing method Google keeps in account hundreds of factors that determine which page is the best possible result, to put forward hundreds, thousands or millions of results.

2. PageRank Algorithm:

Page Rank means the value a web page gets during search queries. The novel PageRank algorithm was deduced by Lawrence Page and Sergey Brin, and so it is named as such. The mathematical calculation of calculating PR is given by:

Where,

= PageRank of web page A

= PageRank of web page T1, which links to web page A.

= No. of outbound links on web page

is the restraining factor which can be fixed between 0 to 1.

First thing to note is that, PageRank does not rank the site as a whole but ranks each page for its content. And relating to the above example, PageRank of web page A is recursively demarcated by the PRs of all those pages which links to page A.

3. Link Analysis and Google Site methods:

These methods denote the exploration of information Google does about website, its pages, the inbound and outbound links and other patterns. These methods look for and evaluate all the following factors in a website:

• The time duration of domain registration.
• The site’s physical address statistics.
• Keyword domains and non-keyword domains.
• The launching date for new domains and web pages.
• Amount of changes in a document and its change frequency.
• The internal linking between the documents.
• Anchor text links and variety of Anchor text.
• Link creation date.
• The changes and removals of various inbound and outbound links.
• Growth arrays of external links.
• External links authority.
• Link value proportions,
• Sharing of links.
• Existence of link duration's.
• Link patterns for new and old.

4. Content Quality matters 95 %:

Google uses robots (the crawlers) to identify and index a web page. And these robots are typical program robots and not human beings. So, these robots are not 100 % deemed to quantify the quality of content every time they crawl a web page. Although Google’s algorithms are smart enough and use quality of techniques like page dissection, natural language processing, links, user behaviour, and many other factors to qualitatively assume about the worth of content and links, but

sometimes even these robots fail to spot the best out of the heap, which occurs due to the wrong

assumption that may have been done by the Google Algorithms.

5. Factors behind PageRank Drops:

The above listed patterns (in point 3) are the most suitable notions that Google follows to rank a page and almost all the time it is spot on. The better these factors are, the better the site’s value and ranking will be, and vice versa. Meanwhile there are instances when a web page sees its ranking dropped even in the scenario of no changes to the above said patterns.

A website or web page can lose its ranking in two other cases as well:

• Algorithmic change:

Google is constantly changing its Algorithm patterns at intervals to help its robots and crawlers to better manage the billions of web pages over the internet, and thousands more adding day by day. These Algorithmic changes can affect the rankings of a web site or web page, even without a slight change in the respective web page.

• Manual penalty:

If a website violates the policy guidelines of Google, the tech giant over-rides its Algorithms and penalizes the site and drops its rankings. These manual penalties happen a lot due to spam practices by many webmasters.

Google is devising new ways day by day for better search experience for the users keeping in correspondence with the evolution of more and more websites are being developed day by day. These are the basic parameters that define the search technique the Google uses to give the result based on your query  within an eye blink.
