Each search engine uses its own software program, but they all work in a similar way. However, Google is the search engine which is the most common in use today. Well, all the search engines perform three basic tasks: Crawling – Indexing – and Ranking.
Basic Tasks of Search Engines
The following are not only the tasks but also the features of search engine that enable it to do amazing things.
- First, They examine the content they learn about and have permission to see; that’s called Crawling.
- Second, They categorize each piece of content; that’s called Indexing.
- Third, They decide which content is most useful to the searchers; that’s called Ranking Ranking.
Search Engines crawl the internet to discover content, like webpages, images, and videos. Each search engine uses computer programs to make their way through the pages; these are known as crawlers, spiders, or bots, which is short for robot. The bots hop from page to page by following links to other pages.
These bots never stop! Their sole purpose is to visit and revisit pages, looking for new links and new content to include in the Indexing, which is the second part of the process. The index is the gigantic list of all the web pages and content found by the bots. The search engine uses this index as a source of information displayed on the search engine results pages (SERP), but not everything the bots find makes it into a search engine’s index. Search Engines may find multiple copies of the exact same piece of content located on different websites.
From the indexed list, the crawlers then find the most relevant pick or piece of content on any website and bring it to your screen. Now, it depends on the expertise, authoritativeness, and trustworthiness of a website carved into its content. These are also the factors of Google’s E.A.T. metric used to qualify websites. A website’s ability to fulfill the E.A.T algorithm makes it able to stand either as the top-ranked website or the least-ranked website.
Still not clear with What is the primary goal of a search engine? Let’s take a deeper dive into the sophisticated journey of exploring search engines.
What is the Purpose of Search Engine?
Imagine you are not searching for a coffee shop but a coffee maker. You might notice that the top-of-the-line Coffee King 2000 has the same word-to-word description on the websites of many major retailers. The description might have been provided by the manufacturer, but now the search engine has a decision to make as to which version to keep in the index. There is really no need for hundreds of duplicates, so it’s unlikely that every page will be.
So, what if you own a website that’s selling coffee makers? You are likely better off writing your own description of the Coffee King 2000. Well, that covers crawling and Indexing, which just leaves us with Ranking Ranking. Think About what happens after you type in a search. The search engine compares the words and phrases to its index and looks for matching results.
But that’s not all. Search engines have become an advantageous ground for businesses, allowing them to optimize their online handles like websites and social media with effective search engine optimization (SEO) techniques.
