Do explainer videos still work? They were all the rage a few years ago but I've also heard that people have got tired of long videos and a good old long form sales page is the way to go in 2018. Any fact based opinions?
Both work but these days visitors have less patience with videos. It is not like 2011 when long animated videos were all the rage. You need to have a little text to entice people to watch the video. If all you have in the first screen full is a play button, you will have likely have far less success. But as with all things CRO, test!
