Considering a user’s standpoint, search engines are nothing less than a miracle. All you have to do is input a query into the address bar and the results from the World Wide Web are ranked and sorted within seconds.
Popular search engines like Google and Bing have already started to offer answers directly within the search results. It saves both time and clicks. How do search engines work? Before we get to that let us share what exactly is a search engine.
What is a search engine?
In layman’s terms, a search engine is a combination of two things. One is a database of information and the second is a myriad of algorithms that determine which results should be ranked and returned.
Search engines like Google and Bing comprise of trillions of web pages. The algorithms evaluate multiple factors for delivering a relevant result.
Now the question that comes up here is how the search engines work.
How do search engines work?
To perform effectively, it is imperative for the search engines to know and understand exactly what sort of information is available and present it to users. The aim is to offer the most relevant result for the user. There are three fundamental processes involved, crawling, indexing, and ranking.
Crawling: This is the initial step for a search engine to work. The search engines send out web-crawlers. The web-crawlers are also known as bots or spiders. These web–crawlers review all the existing content of a website.
On reviewing the new and existing websites the bots look at data. The data includes sitemaps, keywords, page speed, URLs, and codes to discover the content types being displayed.
Indexing: Once the website is reviewed, the search engines now decide to organize and segregate the information. The indexing process involves reviewing website data for positive or negative ranking signals and save it in the right location of the servers.
Ranking: While indexing, the search engines start making decisions on where a particular content needs to be displayed on the search engine results page (SERP). The ranking is done by evaluating the different factors depending on the quality and relevancy of the end user’s query.
During this process, the search engines determine how valuable a website is for an end-user. The decisions are again based on algorithms. Once you understand how the algorithms work, it will help in creating better content to improve search engine ranking.
Every platform uses unique ranking factors for determining where the websites fall within the search engine results page. Keeping those ranking factors in mind helps in creating tailored content for specific pages to rank well.
How does Google Search Algorithm work?
Google is the most popular search engine present in the World Wide Web at present. It owns 90% of the market resulting in 3.5 billion individual searches daily. New websites are created regularly. Google finds the webpages by following the links from the existing content that it crawled previously.
Google’s website index comprises of billions of webpages and thousands of gigabytes of data. For organizing such massive information, Google makes use of a machine-learning algorithm called RankBrain and a knowledge base called Knowledge Graph. All these work together to offer the most relevant content to the end-user.
Google checks out five major factors when someone performs a search. These are as follows;
Query meaning: It determines the exact meaning/intent behind the end user’s query.
Web page relevance: So, the intent of the search query is determined. Then they review the content present in the ranking web pages to sort out which one will be the most relevant. Keywords play a vital role here. The keywords present on a website should match Google’s understanding of the query presented by the user.
Content quality: Once the keywords are matched, Google takes it one step further and reviews the quality of the content present on the ranked web pages. This is how it prioritizes the results, looking at the authority of the given websites, page rank, and freshness.
Web page usability: Google offers ranking priority to websites that are easy to navigate, loads quickly, and is responsive.
Additional context setting: This step seeks the previous user engagements and specific settings within Google.
When all these information is processed, Google offers the results in the search engine results page.
How does the Bing Search algorithm work?
Bing is a proprietary search algorithm of Microsoft. It uses an open-source vector-search algorithm known as the Space Partition Tree and Graph (SPTAG) for bringing the results. Since it uses an open-source algorithm, anyone can check out the nuts and bolts code of how Bing search engine works.
As much as Google is hush-hush about it crawls the websites and uses its algorithm, Bing makes things easy. The Bing search algorithm is divided into two separate modules. The Index builder and the Searcher.
The Index Builder works in categorizing the website information into vectors. While the Searcher enables Bing to connect with search queries and vectors in the index. Instead of being a keyword-first model like Google, Bing breaks up information into different data points known as vectors.
The Bing search queries are based on the algorithmic principle known as Approximate Nearest Neighbour. It uses a deep learning and natural-language model for offering search results.
Another major difference between Bing and Google is, Bing doesn’t include pages without ranking authority. Thus, the new pages have difficulty in ranking if they don’t have backlinks of an existing webpage with more domain authority.
To create tailored content for Bing, observe the differences between featured snippets and the top-ranking sites. It prioritizes content differently from Google.
How does the DuckDuckGo search algorithm work?
It comprises of a proprietary web-crawler known as DuckDuckBot to scour through the web pages and its content. Most of the information showed by DuckDuckGo on the results page is compiled from 400+ additional third-party sources. These sources include Yahoo, Bing, and Wikipedia.
Unlike Google or Bing, DuckDuckGo doesn’t capture personal information of their users, including the past searches or IP address. Due to this dedication towards privacy, the algorithm finds it hard to offer personalized results. Again, due to such a focus on privacy,
DuckDuckGo has got the most streamlined results page by far.
Another interesting aspect of this platform is, it allows the users to use customized parameters called Bangs. It enables them to bypass the search results page.
How does YouTube Search Algorithm work?
By far the most popular video-hosting platform is YouTube. The search engine is almost similar to Google that owns the platform. It is primarily focused on keywords and relevancy. The algorithm is broken down into two separate functions. They are, ranking videos in search and surfacing the relevant recommendations.
Few specific reasons why certain videos rank higher than others include, not outwardly defined, like all Google properties. The freshness of the video and frequency of the YouTube channel in uploading the video also works as an important factor.
At present, there are 1.3 billion users on YouTube with 300 hours of video being uploaded every minute. Thus, it becomes difficult for the algorithm to focus on finding ways to sift such a huge amount of data.
YouTube balances on recommending videos based on how recently a video was uploaded and also the individual’s past search behaviour.
In the end, it all comes down to comprehending the end-user requirement. You will not be able to create customized and high-ranking content if you are not aware of what your target audience is looking for.
