What is SEO (Search Engine Optimization)?

Search Engine Optimization (SEO) is the process of improving a website’s visibility on search engines like Google so that it appears higher in search results when users search for related products, services, or information.

SEO helps websites attract organic (free) traffic instead of relying only on paid advertisements. When your website ranks higher, more users visit your site, trust your brand, and are more likely to become customers.

HOW SEO WORKS?

Search engines use automated programs called crawlers or bots to scan websites across the internet.

The process works in three main steps:

1. Crawling

Search engines discover new and updated pages by scanning links and website content.

2. Indexing

After crawling, search engines store and organize the content in their database (index).

3. Ranking

Search engines analyze hundreds of ranking factors like keywords, content quality, website speed, and backlinks to decide which pages appear first in search results.
