That said, educational psychology research suggests that illustrations and entertaining text may result in less retention of important information. It suggests that cognitive interest and emotional interest may be at conflict with regard to educational purposes, such as learning scientific explanations [55].Video or Virtual TourThis study found that visit duration on the webpage linked from social media increased when a video or virtual tour was embedded in the page (e.g. [56]), especially when the video was placed further down the page and seen after reading the text (e.g. [57]). Retention rate increased when viewers were led to YouTube videos (e.g. [58,59]) or playlists (e.g. [60,61]) as many users clicked to watch additional videos.Comments and DiscussionSimilarly to what was found in [14], comments foster discourse sometimes in unexpected directions (e.g. [62]). Arguments growing from user-introduced topics sometimes dominated the discussion and increased the number of comments AM152MedChemExpress BMS-986020 unrelated to the posts themselves (e.g. [63]). The organisation has created a space for more engagement, but has less control of the message. What the organisation can control is how the comments are addressed, either with a response or by enforcing a comment policy [64]. Thus, where comments are concerned, it is important to read carefully for content and tone to really understand the effectiveness of a post.ClickbaitWhen a social media post had a strange image and enigmatic text, readers were intrigued to find out more and lured by the “clickbait” nline content whose main purpose is to attract attention and encourage visitors to click on a link to a particular web page. When comparing a Twitter post in English with its French equivalent (S1 and S2 Figs), the English-language followers had all the information they needed in the tweet so were less motivated to click-through than the French. Whereas the French tweet had 2.5 times the average click-throughs.Tailored ContentScience communication needs to always have the audience in mind, so tailoring content to a given audience is best practise. Take, for example, the visually minded audience of Instagram. A beautiful ALICE detector image [62] had greater than average likes and comments, showing marketing and engagement strategies were fulfilled. For education, the linked webpage also needs to be tailored to the audience. CERN’s Google+ audience enjoy solving weekly quizzes so spent longer on a webpage to solve strange captionless images [65]. Twitter French users who clicked on links TAK-385 solubility leading to a whole publication of content in their native language (e.g. [66]) spent longer on the site and clicked through multiple stories.Human StoryA human focus is one of the most established attention-grabbing features in media, and this is no different for a science-minded audience. One of the biggest stories during the data taking period was that Fabiola Gianotti would be the next Director General of CERN. The comments discussed different aspects of her identity as a scientist, an Italian and a female, relating to her and congratulating her on a personal level. In another example, a Facebook post took people to a series of stories written in the first person [67].
