How do I use robots.txt in my SEO marketing?

Robots.txt is like a filter that guides the search engines on which pages to crawl and which to avoid. To use robots.txt effectively in SEO marketing, it's important to use it to block search engines from crawling pages that contain duplicate content, sensitive information, or pages that are not relevant to your site's overall content. Be careful not to block important pages, such as your homepage or product pages, as this can harm your overall search engine rankings.
