Introduction

SEO, or Search Engine Optimization, refers to the strategies and techniques used to increase the quantity and quality of traffic to your website through organic search engine results. It’s essential for businesses that want to improve their online presence and attract users by delivering valuable, relevant content to search engines like Google, Bing, and others.
