What is SEO (Search Engine Optimization)?

SEO stands for Search Engine Optimization, a set of techniques used to improve your website’s visibility in search engine results pages (SERPs) like Google or Bing.
The goal is simple: attract organic traffic by ranking higher for the right keywords.

It includes three major areas:

1. On-Page SEO — Optimizing content, titles, meta tags, and images.
2. Off-Page SEO — Building backlinks and improving authority.
