Include Topic Clusters

A topic cluster is a collection of semantically relevant content that individually cover smaller themes within an overarching topic.
For example, let's assume, your main blog topic talks about the Workout routine. Include links that relate to other articles that have a workout routine in common, such as:

• 11 of the Best Ab Workouts for Men
• Body-Shredding Spring Workouts
• Building Muscle with a 5x5 Workout
• 27 Fat-Burning Workouts for Women

This will enhance the relevance & give the audience a chance to look at the other articles which they might be interested in, this will also help Google in ranking your content because of the relevancy your website possesses. That's why you must always interlink your articles.
