What is SEO? How does it works

SEO stands for "search engine optimization" it is a technique of making your website on top of SERP for a keyword entered by a user.

In basic terms, it refers to the process of enhancing your website's exposure when visitors use Google, Bing, or other search engines to look for items or services linked to your business. The higher your pages' exposure in search results, the more likely you are to draw attention and attract new and existing clients to your company.

How a search engine works

Search engines such as Google and Bing use bots to crawl on the web moving from site to site, collecting information about those sites, and indexing them. Consider the index to be a big library where a librarian may pull up a book (or a web page) to assist you in finding exactly what you're searching for.

Crawling:

Collect the data and software called crawler, google bot, spider.

When someone writes something into the search field, it discovers what sites are available on the internet. Because there is no central registration of internet webpages, it is continuously adding them to its list. Google recognizes some pages that have already been crawled.

Important places crawler will read

1. Read

2. Description

3. H1 to H6 headings

4. Links

5. File name

6. First line of the paragraph

7. Bold and italics

8. Image alt

Indexing:

Store the data information as per the categories.

Google interprets the data on a page when it is detected. Google examines the material integrated on the webpage, such as videos, photographs, catalogues, and so on. Indexing is the term for this procedure. This data is then saved in the Google index, which is a massive database maintained on computers.

Calculating relevancy:

Calculating relevancy means it is the ranking factors.

When a user searches for anything, Google examines the indexed sites to get the most relevant results. It considers parameters such as language, location, and device. A user in India will get different results for the same search query restaurant near me than a user in the United States. This is how the outcomes differ.

Programmatically, it ranks pages.

This is how Google generates search results after going through a basic yet sophisticated procedure.
