Backlinks, also known as inbound links or incoming links, are links from one website to a page on another website. They are crucial for search engine optimization (SEO) as they signal to search engines that others vouch for your content.

Types of backlinks:

• Dofollow: Passes SEO value to the linked site
• Nofollow: Doesn't pass SEO value but can still drive traffic

Best practices:

• Focus on quality over quantity
• Aim for links from reputable, relevant websites
• Avoid buying links or participating in link schemes
