There’s no second thought to it: every single net user would have, at least, used the famous search engine Google once. However, not many of the net users give it a single thought to how this famous search engine works to provide you endless search results in a flicker of a second. Here’s how it all works:
Google is driven by a unique and expertly-formulated method dubbed Algorithms to search out the information being sought after by the user. In doing so, it’s simply due to these algorithms that Google filters out select results from a whooping number of websites and web pages available on net.
Larry Page and Sergey Brin, the co-founders of Google, are given the credit for the development of these algorithms.
While the listing of these algorithms are considered to be impetrative and expressly considerate, they are regarded as important as any other Government file and are secured within the reach of only Google researchers, developers and other higher officials.
Here’s a list of top five Google algorithms that almost all of us should be aware of in order to make the most of Google services.
1. How Google index web pages to display 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.
There are more than 30 trillion web pages out there on the web, and the number will only grow each day. To navigate from one web page to another, Google makes use of a process known as Crawling through which it searches the web for the most relevant entries.
Following the crawl of all web pages, Google formulates a category of all web pages based on terms of the quality of web site and content to index that particular web page. For every single search, Google search tends to search out the entire web to find around 100mn GB of data for each search.
After the search of web to index content based on quality of website and content, it then makes use of its “String Theory” to script formulas and programs which form the basis of finding out quality results to filter out the indexed pages.
During the process of indexing, Google considers a number of factors that set forth different guidelines to show the first results first, i.e. the best results are shown at the top of the search engine results page. And in such sequence, Google keeps one result after the other to display hundreds and millions of web pages.
2. What is Page Rank?
You must have surely heard of Page Rank, which basically refers to the value of a web page on the search engine, i.e. how qualitative and efficient in terms of quality it is when we talk about its position in search queries. The algorithm was introduced by the co-founder of Google, Lawrence Page and Sergey Brin, and has therefore been named after its founders.
About Page Rank, you must understand one thing clearly, i.e. the Page Rank does not stand for a web site on the whole, and it is rather related to any particular web page depending upon its content.
3. Link Analysis
The Link Analysis algorithm of Google stands for its scrutiny of all the inbound and bound links, web pages, content, and information displayed by a website. In general, the website analysis and, in particular, the Link Analysis algorithm is based on evaluating the following critical elements of a web site.
· Physical address of the website and its statistics
· Age of domain
· Use of keywords in the domain
· Date of creation of new domains, sub-domains and web pages
· Frequency of change or updating of data on the website
· Links displayed on the website and their internal links
· Anchor text and outbound links to different links
· Date of link creation
· Changes in inbound and outbound links
· Authority and sharing of external links
· Proportion and value of links
· Link sharing and growth of external links
· Old/New link patterns
4. Uniqueness of content and its quality
More often than not, it is undermined but the quality of content and its originality does matter a great deal, at least as far as 90 to 95 percent. Google makes use of robots crawlers for the purpose of identifying and indexing web pages.
These robots are, in general, robots, of course! And so, they are not destined to be 100% certain in terms of the quantity and uniqueness of the content of any web page. But then, the algorithms set by Google are competent enough to figure out the quality of the content each time they crawl a web page.
The algorithms set by Google makes use of various techniques such as user behavior, page dissection, links, natural language processing, etc. to asses and rate the effectiveness and quality of the web content. But still, being robots, they sometimes fail to figure out the best content out of a hoard of web sites and web pages out there. And it may happen mainly because of various assumptions that have been set by Google while laying these algorithms.
5. Why Page Rank falls?
You might often wonder why there’s always a drop in the page rank of your web page. Here’s the reason behind fall in the page rank:
As stated above, Google follows various algorithms to estimate the value and worth of a web page or web site and on the basis of its evaluation it provides suitable page rank to a web page, no wonder its estimation is right on the money most of the times.
However, it has often been noticed that page rank may drop significantly even when there’s low or no change in the links, keywords, content quality, and/or in other elements of a web page.
A loss in page rank of a web site may be attributed to the following aspects:
Changes in algorithms:
Google constantly revises its search engine patterns and algorithms to make sure its crawlers and robots easily manage the ever-growing number of web pages on the net. Such changes in Google algorithms can result in slight change in page rank of a web page, without any significant change in the content and features of the particular webpage.
In case a web site is found to be in violation of the guidelines set forth as per the policies of Google, the Californian IT behemoth can place a penalty against the web site by dropping its page rank, depending upon the severity of violation. These penalties may be placed due to various reasons; including spamming.
Google is coming up with various new methodologies to enhance user experience in this age of developing Internet and web usage. These are only a few of the algorithms that Google uses to ensure you get the most appropriate results for all your queries.
