White hat link building is an approach to driving traffic to a website through SEO techniques, such as relevant linking to other, relevant content on the Web.
White hat links boost a website or webpage's rankings among search engines like Google through organic means that enhance users' experience by boosting the quality of content, broadening its scope through relevant links, and so forth.
Unlike the spam-oriented tactic of black hat link building, which attempts to drive traffic to a site without adding value to the content or enhancing user experience, white hat link building aims to educate users. Unlike black hat tactics, white hat link building can be labor-intensive, requiring website designers and content writers to focus on quality content, then interspersing links to bolster the SEO value of the page.
