Focus on high-quality links
With high-quality content comes high-quality linking. When you are deciding on what links to use in your content, make sure the content you are linking to also follows the guidelines that you are using on your own site. High-quality links include linking to other relevant and authoritative pages on your site, as well as high-quality pages outside your domain.
Links that direct your audience to outside your website, or external links, should come from websites that have a high DA score. You can check any website’s domain authority with the tool you decided to use.
You don’t want to use low-quality links or spammy links. These links possess a low authority score and are not trustworthy. Using low-quality links can decrease your domain score and increase your spam score, meaning Google will be less likely to trust and therefore provide your site to others. For example, linking to an article that was out of date, content that is spammy, or to a product that is sold out, will definitely lower all page and domain authority scores.
Due to the fact that external links have an effect on this domain authority metric, it is important that businesses create a link-building strategy, including a link profile. A link-building strategy and link profile will help you keep on top of the links associated with your business site.
