A Basic Guide about Search Engine and How it Works

 

You must be amazed why I have shared the following graphic of search engine result?

This graphic is powerful in itself that I cannot stop myself to share this with you.

Google Search results per second

When I opened internetlivestats.com page to know the Google search numbers, by the time it has already done 67,790 searches just in one-second (red box). Generally, it conducts 56,681 average searches in one-second (black box), which converts to over 8.2 billion searches per day worldwide.

This is the Power of a Search Engine.

Before moving to any technical aspect of Search Engine Optimization, it is necessary to understand the basic functioning of search engines because your website’s visibility is dependent on the search engines results.

Earlier, there were different mediums to market the products and services, like TV commercials, billboards, radio ads, yellow pages, magazine ads etc.

For a focused and loyal customer, these mediums are still performing well.

But for a wider circulation, the Internet is considered a far better medium.

Nowadays most of the people have Internet access in their homes, offices,etc. For every single information, they depend on the Internet and the search engines.

That is why search engines have become the most effective way of learning and monetizing.

While going through all this information above, you all must be wondering What is a Search Engine?

Let’s start with answering this question.

What is a Search Engine ?

Search Engine is a software designed to search for the information on the World Wide Web (www). Or you may call it a medium to find the solutions to your queries on the Internet.

In a simple language, it is like a customer care executive seated at the information window. Responsible to deliver solutions for your search queries in no time (0.52 seconds).

There are various steps that describe the entire functioning of a search engine. We will discuss them one by one.

But first take a look at the below graphic which shows the screenshot of a Google search query.

To get a clarity of the process we first need to understand what is a Search Engine Result Page (SERP).

Search Engine Result Page (SERP):

SERP-Search Engine Result Page

SERP is the first page of a search engine where you type a query.

In the above graphic, I have shown the example of a query i.e. ‘Google Adwords’.

Also, I have used Google Search Engine to search the results.

So I first entered www.google.com in the address bar.

1. Address Bar:

The address bar is like a search box where you enter the name of the website. It acts as a search box for finding address or phone number in a directory.

First, you need to enter the website address (Ex: www.abcd.com or abcd.com ) on this bar if you know it exactly.

If you enter the wrong address, you will land nowhere. The search results will show that this website cannot be reached. So, be particular with what entry you are going to make.

There is another option that will guide you to your desired page. You can open any search engine in your address bar and from there you can search your query.

Nowadays most of the web browsers come with the default search engines settings.

2. Search Box:

When the main page of the search engine is opened, you will find a bar having a blank space and the search button.

This bar is the search box.

Here you can type any query you want to search on the Internet.

3. The Number of Indexed Sites:

When you enter your search query, Google or any other search engine displays the number of results it has fetched.

These search results are actually the number of websites that have been indexed with your search query (“Google AdWords.”)

It also displays the time taken in listing those results.

In the early 90’s search engines were not so much efficient, they took years to list out 10 million websites.

But nowadays search engines can list out almost 10 billion websites in just 0.52 second.

4. Number One Search Result:

The website with the most appropriate content or the most optimised content will display in the first position. This position is the most competitive one.

Website optimisation is very important as this enhances the visibility. Chances of your website being on the first page of the search results depend on this. The optimisation is done to drive the organic traffic to the websites.

Search Engine is like a Xerox Machine. It makes a copy of the document you have.

“The basic difference between a Search Engine and a Xerox machine is that Xerox machine does not store your data but the Search Engines do store your website/document data in the central database.”

How a Search Engine Works ?

A search engine basically works on algorithms which are a top secret.

But still, on the basis of practical experiences and analytical approaches, Google Webmasters have categorised working of search engines.

There are five steps which lead your website/blog/URLs to appear in any search engine. These steps are as follows:

  1. Website Creation
  2. Submission
  3. Crawling
  4. Indexing
  5. Information Retrieval

The first two are the manual process which are undertaken at the user end.

While the last three are the automated process undertaken by the search engine bots.

We will discuss all these steps in detail one by one.

1) Website Creation:

search engine-website creation

Website creation is the most important step. This step decides the future of your website.

So first of all, you need to understand the basic concept of website designing.

There are many steps involved in designing a website.

These steps may vary from business to business. But the below-mentioned steps are a must to follow in building and running a successful website.

  • Niche Decision
  • Information Collection
  • Planning
  • Setting Up new website
  • Designing & Appearance
  • Execution & Trials
  • Maintenance

2) Submission:

search engine-website submission

Creating your website is an important step. But it is not enough to gain popularity.

From this point, the actual process of recognition starts.

If you will not take necessary steps, your website visibility on search engines will take longer time.

This is like searching some unindexed facts in a book. You have to spend a huge amount of time for searching that fact all by yourself.

So after website creation, you must take the first step of indexing the website in search engines.

There are two ways to submit your website to the search engines.

  1. URL Submission
  2. Sitemap Submission
  1. URL Submission

    There are various platforms in search engines that accept the URL of your website to index.

    But there is no guarantee that your website URL will be indexed.

    That is why you should always submit your website to major search engines (e.g. Google, Yahoo!, Bing and Ask).

  2. Sitemap Submission

    Sitemap is submitted in the cases where the size of a website or a blog is huge.

    A sitemap is nothing but a combination of web pages connected in an organised manner.

    These combinations consist of a document used as a planning tool for web design or a list of web pages arranged in a hierarchy.

    This can be in any form in which a search engine can use it to reach the content and index it completely.

    Sitemap is organised in a manner such that a spider bot can easily move from home page to other pages and its components.

    There are two types of sitemaps:

    a) XML Sitemap

    b) HTML Sitemap

    XML Sitemap is invisible and submitted through Google Webmaster tool. A user doesn’t need to recheck the entire thing. He/she can submit and resubmit a sitemap in Google search console. Rest of the things Google itself will take care of. HTML Sitemap is usually written in HTML language. The user cannot submit this to Google Webmaster tool because of the difference in format.

3) Crawling:search engine crawling

Crawling is the main process performed by the search engines. In this, several small spider bots move into the Internet web.

They collect information and bring them back to their central store/safehouse.

We can correlate these web bots with the insects. Their food is text and they follow a path.

For the better collection of text (indexing of website), they need to follow clean paths (no broken links).

Otherwise, they will deviate from their original path and the information they carry will not be sent to the central web server.

So it is important that your website should be well organised that can be easily found and indexed by Google bots.

4) Indexing:

When spider bots search or crawl over links they start with a list of URLs called seed URLs.

Then they index all hyperlinks and make a copy of that web page.

All the web pages cannot be indexed altogether. Because the bandwidth of crawls is not infinite. They are efficient and scalable.

So when these crawlers come to the central server database. They transfer all the data to the server for analysis.

There are certain crawling policies on which indexing of the pages depends.

On the basis of these policies, either all the pages or some of the pages get indexed in Google or any other search engine server.

This reflects when a user tries to search for a query related to your website’s keyword rich text.

5) Information Retrieval:

search engine information retrieval

When a user types something on Google or any other search engine, the search engine lists all the results related to that query.

Several web spiders start fetching web pages and they follow links from one point to another.

Soon they list billion of pages. Imagine how fast they search. Thousands of machines/computers work together to fetch the search results.

Just wonder, out of those thousands of results how Google decides which is the best possible solution?

Well, it evaluates more than 200 question for that. Like,

  • No. of pages having the same phrase or keyword ?
  • Is the phrase in the SEO title or meta description ?
  • Is Keyword/phrase in the URL ?

and so on…

It combines all these answers and shows the best result.
