Before explaining how SEO works, we need to understand Search Engines that play a significant role to provide intended user results.

Search Engine is an online tool that provides related results from its database when users search for some queries (keywords).

How does Search Engine work?

Search Engines (i.e. Google, Bing, etc.) basically works on complex mathematical algorithms to show different results according to user intent.

Let’s take a deep dive!

There are lots of search engines available on the internet. You’ll find some bit of difference among them, but the basic functionalities of search engines are mostly the same.

Here are some basic fundamentals of search engines.

  1. Crawling
  2. Indexing
  3. Producing Results


Search Engines have bots (automated software agents) whose work is to scan each website present on the internet worldwide. The process of finding links and following the path is called crawling.


After crawling site to site, search bots add the crawled links in the online web libraries (database), this process is called indexing.

Remember, it is not necessary that search bots can index all the links. If there is a no-index tag found on the web page, search bots won’t index them.

Producing Results:

When a user submits a query, search engines check all the indexed records based on its algorithms and picks the best result in an ordered list.

Google’s algorithms are the only primary and important source that brings out intended user results.

How does SEO Work?

Basically, every search engine work on the defined algorithms to provide the best results according to the user’s need. These algorithms analyze the hundreds of ranking factors on the website to find out which site has better content to show in search results (SERPs).

In this way, the search engines manage the order of web pages with respect to the given user query.

It means you have to obey the defined ranking singles (algorithms) to rank in the SERPs. It would be quite challenging to cover all the search engines ranking singles for your site.

But don’t worry, Google owns 92% of the market share. So, start optimizing your site for Google instead of others.

Google has over 200 ranking factors. If you follow them for optimizing your site, you’ll almost cover every search engine. Mainly, your goal is to confirm that a search engine sees your website perfect for the user’s search.

Why is SEO important?

Everyone wants organic traffic to his website, and SEO is a significant source of traffic. As I discussed earlier, 70% of the users search online before purchasing any goods or services.

You can represent your business online to get valuable customers. SEO is all about understanding what people are looking for online. Google also provides the location-based data by its tool called Keyword Planner. So, you can quickly analyze which search terms are being used by users.

People might be searching for information, products, or services. According to research, 3.5 billion searches are done on Google daily. No matter, you have a small business, but people are searching for it.

In short, SEO is perfect for your online business visibility and branding.
