SEO stands for Search Engine Optimization. It's the process of optimizing your website and its content to rank higher in search engine results pages (SERPs) for relevant keywords and phrases. The goal of SEO is to increase visibility and drive more organic (non-paid) traffic to your website.

SEO involves various strategies and techniques, including:

1. Keyword research: Identifying the terms and phrases your target audience is searching for.
2. On-page optimization: Optimizing elements on your website such as title tags, meta descriptions, headings, and content to make them more relevant to your target keywords.
3. Off-page optimization: Building backlinks from other websites to improve your site's authority and credibility.
4. Technical SEO: Improving website speed, mobile-friendliness, crawlability, and other technical aspects that affect search engine rankings.
5. Content creation: Producing high-quality, relevant content that addresses the needs and interests of your target audience.
6. User experience optimization: Ensuring your website is easy to navigate, loads quickly, and provides a positive experience for visitors.

By implementing effective SEO strategies, you can improve your website's visibility in search engines like Google, Bing, and Yahoo, ultimately driving more organic traffic and potentially increasing conversions and revenue.
