"One of the main challenges for fact-checkers seems to be to better and more effectively reach their audience. That means, on the one hand, improved skills and capacity to reach out to a specific group of followers, but also techniques to more efficiently use social media as an audience generation tool. Effective use of social media turns out to be a challenge of high importance for African fact-checking organizations in our sample in particular, which have thus far been slow in building a strong follower base on social media such as Facebook and Twitter. Credibility has also been mentioned as a major challenge for factchecking groups, with 22 out of 30 groups that responded in our poll saying that the challenge of gaining or maintaining credibility is “very important” or “fairly important.” Achieving a higher impact is an important challenge for many factchecking organizations as they seek methods that would help them to both measure and increase their impact. All African fact-checking groups included in our research indicated the challenge of impact to be “very important.” Impact of fact-checking remains a research gap as there is no solid evidence to understand how effective fact-checking is."
