Linking Root Domains (LRDs) refers to the number of unique root domains that link to your website. A root domain is the top-level directory of a website, for example, www.example.com. If several pages from the same domain link to your website, it will still be counted as one LRD.
Linking Root Domains are important for SEO because they play a crucial role in determining a website’s overall Domain Authority. Domain Authority is a metric developed by Moz that predicts how well a site will rank on search engine results pages (SERPs). A higher number of LRDs can lead to an increase in your site's Domain Authority.
To identify your LRDs, you can use tools like Moz or Ahrefs. These tools can give you an overview of all the websites that link to your site and provide other valuable metrics like referring domains and backlinks.
Link building is crucial when it comes to building LRDs. There are several ways to build links, including creating high-quality content that people want to link to, guest posting on relevant websites, and participating in social media discussions related to your niche.
While having a lot of LRDs may seem like a good thing, having too many low-quality backlinks can harm your search engine rankings. It's important to focus on building high-quality links from reputable sources rather than trying to accumulate as many links as possible.
Referring domains refer to all the unique websites that link back to your site, while LRDs only count unique root domains that link back to your site. For example, if two pages on the same domain link to your site, it will count as one referring domain and one LRD.
