The advert appeared 388,630 times on Facebook, and there were 259 clicks on it (at a cost of £76). It was not possible to determine how much traffic came to the survey directly from the advert or from the use of Facebook generally via other means, but in total we received 754 completed surveys via Facebook (Fig. 3). Fig. 3 Facebook advert Advert in mumsnet and gransnet Mumsnet is the UK’s biggest online network of parents. According to the site there are 50 million page views and 9 million visits per month. selleckchem The Times newspaper reflects that it is ‘The country’s most popular meeting point for parents” (www.​mumsnet.​com). ‘Gransnet’ is a subsidiary website, particularly

targeted towards grandparents. We wrote a short advert that Mumsnet and Gransnet put onto one of their pages for regular followers. It appeared as this: We’ve been asked by the Wellcome Trust Sanger Institute to ask Mumsnetters to fill in a survey they’re running on genetic testing. Here’s what they say about the survey: “Your genes can tell you about your past, present and future medical health. Very soon, full genome testing (the ability

to look at all 20,000+ genes) will be available in the health service. Like Angelina Jolie, you could have a genetic test and find out what you are at risk Ralimetinib cell line from. What would you want to know? Alzheimers? Cancer? Mental health issues? Or maybe you’d rather not know? Our research from Cambridge ( www.genomethics.org ) will have a direct impact on the way this testing is offered, find out about the possibilities and the ethical issues raised by this (no prior knowledge about genetics needed).” The survey is open to everyone so please take part and pass on to any friends/family you think might be interested.Please click here

to take part. Payment for the above advert cost £1,620, and we received 1,405 completed surveys; thus, each completed survey cost just over £1. Viral spread of survey Due to the nature of the World Wide Web it is impossible to control how another user chooses to re-report and debate issues that the Genomethics project initiated. Other websites chose to write blogs based on our press release and wrote commentaries on the research on Facebook sites and via Twitter; participants also emailed their friends Non-specific serine/threonine protein kinase after PLX3397 ic50 completing the survey and ‘Liked’ it on Facebook and linked to it on Twitter. We had no influence on whether and how this was done, but the net effect was that a ‘viral’ or snowball process emerged whereby participants visited our website via routes completely unconnected to any of our active recruitment methods. For example, an online Polish newspaper ran an article on the study and provided a link to the survey (this was only discovered via an opportunistic google search). The net result of this was the direct recruitment of 90 new Polish research participants. Results Cleaning up of data The survey received 11,336 hits.
