There are many tutorials on SEO, but most of them are in English so many people have trouble understanding them properly. In Bengali, there are tunes about SEO, almost all of them are entry level. So I will try to give you an idea about SEO from Entry level to Advance level, although the basic rules are the same. So it is very important to know the Fundamental rules for SEO. (Although I have a new account on Tech2Time, I have been with Tech2Time for a long time. So I know there are many SEO. So if in my writing There is a mistake. I will be very happy. SEO is a subject that can be learned by sharing knowledge. Then you can google or let me know. I said a lot, let's go to the main context.

What is search engine optimization (SEO) and why is it used?

There are two types of search results.

  •  Organic
  • Paid.


We will talk about organic search results here. Because it is free and paid search result, if you spend money, you can give Ad.

First we need to know how search works.

The search engine mainly works with two components:

  • Crawler - It mainly collects information from different websites (via spider, robot / bot) Here Search Engine or SE mainly follows any link then collects information and stores that information in their database.
  • Algorithm - Here the search engine analyzes the information obtained, ranking the content of different pages according to relevancy and quality. SE's algorithm depends on many factors.

What is SEO?

SEO- search engine optimization. Defined in Bengali, SEO is a set of rules / techniques through which a website can get more visitors / traffic from different types of search engines (GOOGLE, MSN, YAHOO etc). In fact, if you can get any website to the first page of search engine through SEO, the chances of getting visitors also increase a lot.

To put it more simply: if we want to download a song, all we usually do is search for that song line on google. Now notice that after we press the search button, google shows the names of some websites where we can get that song. In this way google shows the names of 10 websites per page. Now you may be wondering why some sites came to the front page, and why the rest of the websites went to the back page - is Google doing what it wants or is there some other reason behind it? Surely there is something special about the first page sites, which other sites do not have. Nothing special about this is the SEO strategy, which allows you to take your website to the first page. And the first page means more visitors.

Those who are new to SEO can follow Google Webmaster Guideline. If you follow basic rules then you don't have to worry much about SEO. We make a website for visitors, so if you can present to them exactly what they want to know, then 50-60% of you are SEO.

Why a visitor searches: Either they're looking for an answer to a question, or they're looking for a solution to a problem, or they want to meet their needs. If you can answer their questions, solve problems or give them the information they need through your site then you have no more worries.

SEO is usually divided into 2 parts:

  •  On Page SEO and
  • Off page SEO.


On page SEO: Simply put, what you say about your website and off page seo is what others say about you.

Uses of SEO:

Suppose you have a baseball site that is currently ranked # 10. If you want someone to search for "Baseball Cards" in the search engine, it will show in the # 1 position - to do that you have to SEO that site. SEO is usually done using a popular search term or keyword. Now if you want to take your brand name to the top by SEO and be successful, it is not exactly called SEO. Because search engine is smart enough and can easily distinguish your company name and keyword. And the main thing is, the more competition for that keyword, the harder it is to rank in that keyword.

For this it is better to do some planning before starting SEO. Suppose you open a new site, which already has millions of competitors, and another one builds a site that may have 1000 sites, now you tell me where it will be easier to compete in millions or within thousands?

For this reason, it is very important to choose the right keyword for proper SEO planning of the site. If the keyword selection is not correct, you will not get your desired results. This is because people use these search terms when they search for something. So if you don't know what people are looking for, how do you meet their needs?
