SEO, or Search Engine Optimization, is the process of optimizing a website or online content to improve its visibility in search engine results, like Google. The goal of SEO is to attract more organic (unpaid) traffic to a website by making it appear higher in search engine rankings.

SEO consists of several key elements:

1. On-Page SEO: This involves optimizing content directly on your site, including:
- Keywords: Using relevant keywords that users might search for.
- Title Tags and Meta Descriptions: Adding concise and keyword-rich titles and descriptions.
- Internal Linking: Linking between pages on your site.
- Content Quality: Ensuring content is informative, original, and valuable.

2. Off-Page SEO: This involves actions taken outside your site to improve its authority and ranking:
- Backlinks: Getting links from reputable external websites.
- Social Signals: Gaining visibility through social media interactions and shares.

3. Technical SEO: Ensuring the technical aspects of your site are optimized, like:
- Site Speed: Making sure your site loads quickly.
- Mobile-Friendliness: Ensuring your site works well on mobile devices.
- Crawlability: Making sure search engines can easily index your content.

By implementing SEO strategies, you can help your content rank higher on search engine results pages (SERPs), which can lead to increased traffic and conversions.
