What is search engine optimization?

We are going to talk about what is search engine optimization. You are going for an interview or you will train someone, or you will work anywhere, and you tell a client that I want to SEO your website, then for that, you should know what is Search Engine Optimization? Search Engine Optimization is made up of two words.

First is 'Search Engine' & second is 'Optimization'. First, let's talk about search engine.

search engine

So what is a search engine? search engine is a software system that is designed in such a way that it can search the information according to the query of the user to find information from the World Wide Web, i.e., the Internet. Because you know that thousands of websites or millions TB of data are stored here.

Optimization

Now let's talk about optimization. So what is optimization? Optimization means using something perfectly. So what it means to say here is that we do the best optimization of the search engine in search engine optimization, i.e., Use the search engine to your advantage in a better way. Now think about how you can use the search engine. If I have a website or a business, then I can make sure that any person types anything related to my business, product, or service in any search engine, so he should see my website at the top. So this is the best use of search engine in optimization that we do in search engine optimization. The next question is, do we optimize search engines? The search engine is a software system which has been made after a lot of effort and is a very secure network. I take Google's example. Can you tamper with Google's backend? Can you take your website to the top by changing its algorithm or coding? No. If I talk in simple language, then you cannot optimize the search engine in search engine. You optimize your website for a better the way so that you can get the best out of the search engines. For example, I have a designer showroom. I make designer dresses. This is my business. And I want that whenever someone searches for designer dresses in Delhi, then my website should be visible at the top. This is an amazing thing. So that's what we have to do is to optimize our website in such a better way that they appear in the top ranks of search engines, which will boost my business, increase my conversion rate and ultimately make my business grow.

How Search Engine Works?

See, when I was not in this field, I used to think that how do search engines work? Whenever we type something, like if I type black dress on Google,the search engine goes to the websites and checks where the black dress is and gives me the results.I used to think like this, but it doesn't happen. Before you type anything, before you type any keyword, Google plays a very important role. It has already done some functions before and after that it shows you the results.

So one by one, step by step, we will understand how this search engine works.

So you know that there is a lot of data on the internet, that is, the world wide web. A lot of data, that is, thousands of millions of TBs are stored here. So whenever the creator uploads that data, like if I made a website, I uploaded a blog, uploaded some images, made any changes to my website or a new website came, then in this way, Google's crawler, we call it, then the crawler goes and crawls all that data, that is, it hangs on it. It sees where the thing is, what content is on this website, it is crawling all the content before searching anything, it is seeing where the thing is and it picks up all that data and sends it to its local server.

local server

The meaning of local server is that it is saving in Google's own hard disk. So what did you do here, like I am talking about Google, so that you can understand better, but here I am talking about every search engine. So the crawler of the search engine crawls the data, picks up all the data available on the internet and puts it in its local server. We cannot see the local server, it is their local hard disk, you cannot access anyone's hard disk. So in the local server, the indexers of Google, what do you call them? Indexers. So Google's indexers, what do they do to these local servers? They do indexing, that is, they divide them into different categories.

Like a website has just been created, there are a lot of dresses like black dresses, pink dresses, maroon dresses, I am just taking an example, okay?So Google will pick up the data from there and put it in the local server. Now what will the indexer do? That will separate the black dresses, separate the black shirts, apart from that, the shirts will be in a separate category.So the work of the indexer is to categorize,that all the data on the local server of the search engine, divide it into categories, so that Google can give relevant results to its users. So this is the work of indexers, okay?

Example : So for this, I want to give you an example so that you can understand this process very well.
Look, I have a library, I manage a library. So now I would like to explain this concept as an example. First, I have a library, okay? So I bought a lot of books from somewhere for my library.
And I ordered a lot, so a loading taxi came, in which all my books came. So I have 3 person to help me , so I sent one of them to go and pick up all
the books from that truck. So what did that person do? He picked up all the books and put them in my library's main hall.
So my first person's name was Crawler, that is, Spider.
So what did he do?
He picked up the data and threw it here, that is, he put it in
my local server, that is, in my hall.

Now I told my second person to go and pick up the books there, category-wise.
Books of Hindi became different, books of English became different.
Then in Hindi and English, like literature, economics, maths, textbooks, magazines, newspapers became different. So I told him to put all the shelves of all the books in all
these categories. So my second person went, he picked up all the data, that is, all the books, and put them in the categories.
Now my second person was called Indexer. Because what did he do? He saved my data in the categories.
Now the data that I have collected after the categories are made, is my main server, that is, the main server of Google, which is connected to us.
Now the work of 2 persons is over here. So now it's the turn of the third person, that is, now it's the

turn of the third person.
Now listen to what the third person does. Whenever a user comes and says that I want this thing, then the third person will run and go.

And wherever the indexers have kept the book, he will bring it to him according to the query of the user. Like he says that I want a book of literature in English, then
that person will go and find it, take that book and give it to my user.
And how will he give the book to the user? He will give a very relevant book, whatever he wants. So this is what Google does.
First there was crawling, then there was indexing, and then the ranking algorithms of Google.
Like we will talk about a lot of ranking algorithms, how Google gives ranking.

So on the basis of those ranking algorithms, Google shows you the results in the ranking. Because all the indexing is done, the categories are divided.
But in it, which result do you have to show first, which one to show on the second number, which one to show on the third,
which images to show in the images, all these things are done.

by the ranking algorithm. So the first was crawling, the second was indexing, and in the third we are talking about ranking. So whenever you type anything on Google, the result page you see is called SERP or SERP means search engine result page. So on the search engine result page, whichever ranking you see the results,

Who decides it?

Google's ranking algorithm decides it.

Now what are those ranking algorithms? We will understand this in the next post. And how to work on all those ranking algorithms, how to understand who, we will talk about all this in this course. The course you are watching this video, you will get the link in the description box, in which we are watching the complete SEO course.

Now some people have a doubt that we have to work only on ranking or rank. The definition of SEO is that we have to rank on top. No, we will not only talk about ranking, we will also talk about how you can do better crawling of your web pages, of your website, how can you do better indexing. And then we will talk about ranking. So I will not leave any point of yours, we will complete all the points in this course.
