Okay, straight to the point. I am in confusion. I am in process to expand my online business (2 web portals in niche areas). Currently, my revenue is only ad-based. I am getting 2 views - to develop paid info products; OR to enhance free content & increase ad revenue. As time is limited, developing paid content will surely hit site visitors dropping ad revenues. I am also not sure whether people will buy or not. Any wisdom or thoughts to help me out?
