What are backlinks?

Backlinks are links from other websites that direct users to your site. They play a crucial role in search engine optimization (SEO) as they help improve a website's authority and visibility in search engine results. When a reputable site links to your content, it signals to search engines that your content is valuable and relevant, which can lead to higher rankings.

Establishing a robust backlink profile involves building relationships with other websites, creating valuable content that others want to link to, and promoting that content effectively. Backlinks also drive referral traffic, meaning that users who click on the link are directed to your site, providing potential engagement and conversions.

The other choices do not accurately define backlinks: images on a website serve a different purpose in terms of visual content, navigation links are internal and help users move between pages within the same site, and social media shares are about promoting content on social platforms rather than linking back to a site from others.
