Link building is an “off-page” search engine optimization (SEO) strategy to earn links to your website. Links to your site can be thought of as an indication of how popular and connected your site is. Search engines like Google have relied on both the volume and quality of website links to indicate your website’s value. High-quality links indicate that other sites are willing to send their visitors to you and can improve your site’s domain authority which improves your SEO value and can lead to increased search rankings and organic traffic.
There are many ways that an SEO agency can perform link-building strategies including manual outreach like direct email to website owners, creating high-value content (blog posts) that attracts others, or through digital PR tactics that generate buzz. Link building is considered to be one of the most challenging aspects of a proper SEO program which leads to most opting to hire link-building agencies.
