How to Improve Reader Engagement?
Topic clusters can improve reader engagement. You build a page (AKA pillar page) containing in-depth information on a topic, a very long page, and you link it to relevant internal pages. The technique works great with readers and traffic. The search engines will find the page as highly useful to readers and promote it in their ranking systems. Google favors topic-clustered pages with its proprietary algorithm. In simple words, topic clusters create the much-needed authority, which in turn benefits your site with higher rankings.
