What is SEO?

SEO (Search Engine Optimization) is the practice of improving your website so that it appears higher in search engine results when people search for relevant keywords.

For example, if someone searches for “what is SEO” on Google, websites that are properly optimized will appear on the first page.

The higher your website ranks, the more organic traffic you get.

Organic traffic means visitors who come from search engines without paid ads.

Why is SEO Important?

SEO is important because:

  • It brings free traffic
  • It builds credibility and trust
  • It generates long-term results
  • It helps businesses grow online
  • It works 24/7 once content ranks

Unlike paid ads, SEO continues to send traffic even when you stop investing money.

How Do Search Engines Work?

To understand SEO, you must understand how search engines work.

Search engines like Google follow three main steps:

1. Crawling

Google bots scan websites to discover new pages.

2. Indexing

After crawling, Google stores the pages in its database.

Google shows the most relevant and high-quality pages at the top of search results.

Your goal with SEO is to make your page easy to crawl, index, and rank.
