Sliders (or carousels as they are sometimes known) are content blocks that typically sit at the top of a website, in particular a home page. The idea is that they allow you to cram a lot of information into the most important retail space on your website. You can get multiple messages across (offers, key content, calls to action), pushing various different types of customers to the parts of your website that is suitable to them. Except here’s the thing. They don’t work.
