External Linking

Check whether the statistical or relevant content has a cited source, whether the company has a copyright content policy for that page, and if the content is based on research.

Use Relevant Anchor Text: Your anchor text must be relevant to the content on the external website you linked to.

Open External Links in New Tabs: Allowing external links to open in other tabs will not drive them directly to those websites. The user has to move to another tab only if they want to seek more information from the external source. This way it enhances user experiences and helps you increase your visitor time.
