SEO
What is SEO and how does it work?
SEO stands for Search Engine Optimization. It’s the process of improving a website so it appears higher in search engine results—like on Google or Bing—when people search for something relevant.
🔍 What SEO actually means
Imagine you run a website. When someone searches for “best running shoes” or “how to bake a cake,” search engines scan millions of pages and decide which ones to show first. SEO is about making your site one of those top results.
⚙️ How SEO works (simplified)
Search engines use automated programs (called crawlers or bots) to explore the web and rank content. The process has three main steps:
1. Crawling
Search engines send bots to discover pages on the internet.
They follow links from one page to another, constantly finding new content.
2. Indexing
Once a page is found, it’s stored in a huge database (index).
The search engine analyzes:
- What the page is about
- Keywords used
- Images, videos, and structure
3. Ranking
When someone searches, the search engine decides which pages to show and in what order. This ranking depends on many factors, including:
- Relevance – Does your content match the search query?
- Quality – Is your content useful and trustworthy?
- Keywords – Are the right words used naturally?
- User experience – Is the site fast, mobile-friendly, easy to navigate?
- Backlinks – Do other websites link to your page?
🧩 Types of SEO
1. On-page SEO
Things you control on your website:
