What Is SEO?
SEO (Search Engine Optimization) is the process of improving a website so that it ranks higher on search engines like Google, Bing, and Yahoo.
The main goal of SEO is to increase organic (free) traffic to your website by making it more visible in search results.

If someone searches “What is SEO?” on Google, the search engine shows the most relevant and optimized websites at the top. Those websites are ranking there because they have implemented good SEO practices.
How Search Engines Work ?
Before understanding SEO deeply, it is important to know how search engines work.
Search engines follow three main steps:
1. Crawling
Search engines send bots (also called spiders) to scan websites and discover new pages on the internet.
2. Indexing
After crawling, the search engine stores and organizes the information it finds in a huge database called an index.
3. Ranking
When a user searches for something, the search engine shows the most relevant pages from its index and ranks them based on various SEO factors.

SEO is essential for anyone who wants visibility online. Here are some major benefits:

Cost-effective marketing strategy
For bloggers, businesses, and digital marketers, SEO is one of the best ways to grow online without spending money on ads.
