One area that every niche has a demand for is information about events related to their industry. Conferences and webinars are always of interest to people trying to learn more about their industry, and many of the events offer affiliate programs. But even if there are no affiliate programs for the events, having a page dedicated to them will bring people back to your site where they may subscribe to your content, since they rely on you to provide updated information in this area.
This addition of needed information builds your authority for providing valuable content, so when you write about other topics you will be seen as someone providing value. Your recommendations and reviews of products and services, that bring you affiliate income, will be more likely to convert.
