SEO (Search Engine Optimization) is the process of improving a website’s visibility on search engines like Google, Bing, and Yahoo. The main purpose of SEO is to help a website appear higher in organic (non-paid) search results so that it receives more traffic from people who are searching for relevant information, products, or services.

In simple words, SEO ensures that when users search for something related to your business or content, your website appears among the top results. Search engines aim to show the most relevant and high-quality results to users, and SEO helps your website meet those standards.

⭐ Detailed Explanation

1. Purpose of SEO

The primary goal of SEO is to increase website visibility. When a website ranks higher on search engine results pages (SERPs), more users visit the site naturally. This results in:

Higher brand awareness
More leads and sales
Increased trust and credibility
Better user engagement

⭐ 2. How SEO Works

Search engines work by crawling, indexing, and ranking pages. SEO helps optimize each of these processes:

a) Crawling

Search engine bots scan web pages to understand the content.

b) Indexing

Search engines store and organize pages in their database.

c) Ranking

Search engines display pages based on:

Relevance
Quality
User experience
Website authority

SEO ensures your site meets all these ranking criteria.

This involves optimizing elements on your website such as:

Keywords and content quality
