Search Engine Optimization, or commonly called SEO, is the practice of optimizing websites to improve their visibility and ranking in search engine results pages (SERPs). The goal of SEO is to increase organic (non-paid) traffic to a website by making it more relevant and authoritative in the eyes of search engines like Google, Bing, and Yahoo.

Key components of SEO include:

• On-page optimization (This involves optimizing individual web pages to make them more search engine friendly. It includes optimizing content (using relevant keywords, headings, and meta tags), improving page speed, enhancing user experience, and optimizing images and other media.)
• Off-page optimization (This refers to activities performed outside of the website to improve its search engine ranking. This includes building backlinks from reputable websites, social media marketing, influencer outreach, and online reputation management.) 
• Technical optimization (This involves optimizing the technical aspects of a website to improve its crawling and indexing by search engines. It includes optimizing website structure, fixing broken links, implementing schema markup, and ensuring mobile friendliness.) 
• Content optimization (Creating high-quality, relevant, and valuable content is crucial for SEO success. Content should be optimized for keywords, user intent, and readability while providing value to the audience) 

By implementing effective SEO strategies, websites can attract more organic traffic, increase visibility, and ultimately achieve higher conversion rates and business success.
