If you have a website, you want people to find it on Google. This is where SEO helps.
SEO (Search Engine Optimization) is the process of improving a website so that it appears higher in search engine results like Google and Bing. When your website ranks higher, more people can visit it without clicking on paid ads.
For example, if you sell shoes online and someone searches for “best running shoes in India”, SEO helps your website appear in the search results.
SEO is important because it helps you:
- Get more organic (free) traffic
- Improve your Google rankings
- Build trust with users
- Get more leads and sales
- Grow your business in the long term
Whether you have a blog, an online store, or a business website, SEO can help you reach more people.
How Does a Search Engine Work?
Before learning SEO, you should know how a search engine works. When you search for something on Google, it does not search the internet at that moment. Instead, it shows results from the pages it has already saved in its database.
A search engine works in three simple steps.
1. Crawling
Google uses small programs called Googlebots or crawlers. These bots visit websites and find new or updated pages by following links.
Example: You publish a new blog on your website. Googlebot visits your website and discovers the new page.
2. Indexing
After finding your page, Google reads the content to understand what it is about. If the content is useful, Google stores it in its database. This process is called indexing.
If your page is not indexed, it will not appear in Google Search.
Types of SEO
There are three main types of SEO.
On-Page SEO
On-Page SEO means optimizing the content on your website.
Some common On-Page SEO activities are:
• Doing keyword research
