When someone searches for something on Google, SEO helps your website appear in front of the right audience at the right time — without paying for ads.

  • Understanding what people search for

  • Creating content that answers those searches

  • Structuring your website so search engines can understand it

What is SEO?

Before learning SEO, you must understand how search engines work.

Search engines follow three main steps:

1. Crawling

Google uses bots (called crawlers) to discover pages on the internet by following links.

2. Indexing

After crawling, Google stores the page in its database (index) and understands:

  • Topic of the page

  • Keywords used

  • Content quality

3. Ranking

When a user searches, Google ranks indexed pages based on hundreds of factors such as relevance, content quality, and user experience.

SEO is the process of influencing this ranking.
