Using social media is one of the best ways to connect your survey with the wisdom of the crowd. Getting noticed in this competitive environment can, however, be a challenge. To tackle this issue, we’ve made it easier to have your surveys stand out on social networking sites. There is a new option in the General Settings section of the editor that allows you to specify the image that is displayed when you’re sharing a survey link around on Facebook or Twitter. This image can, for example, be a screenshot of the front page of your survey and it will replace the generic Maptionnaire thumbnail image.
The rule of thumb is that you should use images that are large enough (FB minimum 1200×630, Twitter minimum 1500×1500) but at the same time limiting their size to 5MB. Check out the more specific image guidelines of the social platforms here: Facebook and Twitter. Both also provide tools that let you preview posts and tweets before sharing them.
Finally, it’s good to be aware that Twitter and Facebook make copies of the images you’re adding. These copies aren’t necessarily updated immediately when you’re trying to change an image. To force Facebook to forget the previous image and let you experiment with a new one, go to Facebook’s sharing debugger tool and select “Fetch new information” or “Scrape again”. With Twitter, this is unfortunately not possible at this time. You will just have to wait for them to revisit your page.
