Basic SEO course – Chapter – 6

Multiple Google algorithms together make a ranking system, that is designed to short hundreds of billions of web pages already stored in the index of Google. Idea is to identify the most relevant result for a given query in a fraction of a second and make a result page that helps users to find what they’re looking for. Google’s ranking systems are made of a whole series of algorithms to identify the most useful information. Search algorithms work on many underlying factors, some of them are for understanding the meaning of a query, identifying the relevance of web pages, checking the quality of content, understanding the usability of web pages, and reading context and settings of the end-user.

Let me explain, we can not speak for Google, information written here takes insight from the official page talking about Google’s algorithm.

Let us start with understanding the meaning of user query
It is indeed very most important to understand what a user is searching for, the intent behind a user query. Google’s language module tries to decipher what strings of words a user is looking in the index. Applying natural language understanding, and connecting all word strings, spelling mistakes Google’s algorithm knows what is meaning of search. According to Google, it took over five years to develop this system and improve results that we see today. Apart from synonyms, algorithms also identifies the category of information searched, it is a specific search, news search, or broad information?
The user is looking for local information, local shop address, or a research paper, based on these factors it shows fresh content or old page with authority content.

Calculating relevance of web pages based on searched word meaning
This algorithm calculates the relevance of the web page by analyzing content written. It checks the words on a page, words in headings beyond simple keyword matching to check if page answers the questions, not just repeating the questions. For example, if a user is looking for car information, the page should contain all information related to that car, pictures of car, engine information, specific details.

Checking quality of web pages
The next algorithm determines the reliability of the web page, to check expertise, authoritativeness, and trustworthiness on a given topic searched by end-user. It checks if other people are giving value to that content by linking, by talking about that page on social platforms, forums, etc but not limited to. There is a spam algorithm to identify artificial links to a spammy bad quality page.

Understanding Usability
It is all about how well a user can use that page if that page is designed to work on different platforms (device compatibility), the usability of the page, easy navigation, website owners are free to improve quality for this and Google informs in advance if they are going to add a new algorithm and what that is going to do, for an example in January 2018 Google announced that our algorithms would begin to consider the “page speed” of sites, six months before the changes went live. To help website owners, Google provided detailed guidance and tools like PageSpeed Insights.

Context and settings
Location information, search history, and search settings plays a key role in what is visible in the result page. It identifies country and location to determine result eleven to that area. For example, if you search for cricket in India, Google will display the latest game information related to Indian cricket. It will rank relevant pages having the latest information about that game.

Apart from these known Google’s algorithms, there are many that keep search results neat and user-specific, and location-specific. Some of the most talked algorithms are BERT (Bidirectional Encoder Representations from Transformers), Panda, launch on February 24, 2011, Penguin, launched on April 24, 2012, Hummingbird, launched on August 22, 2013, Pigeon, launched on July 24, 2014 (US); December 22, 2014 (UK, Canada, Australia), Mobile, launched on April 21, 2015, RankBrain, launched on October 26, 2015, Possum, launched on September 1, 2016, Fred, launched on March 8, 2017.

Assignment: Make a list of all known Google’s algorithms and write what they do, when they are launched, what king of public information known about them on official Google’s page.
