SEO, or Search Engine Optimization, is the practice of enhancing a website to improve its visibility on search engines like Google, Bing, or Yahoo. The goal is to increase organic (non-paid) traffic to the site by ranking higher in search results for relevant keywords and phrases.
Techniques involved in SEO include optimizing website content, improving site structure, and enhancing user experience. This can involve keyword research, creating high-quality content, optimizing meta tags (like titles and descriptions), improving page loading speed, and ensuring mobile-friendliness.
By employing these strategies, businesses and individuals can attract more visitors, ultimately leading to increased brand awareness, customer engagement, and conversions. It's a constantly evolving field as search engines update their algorithms and ranking factors.
