#4 – Too Many Effects
When people visit your site, they want to be in control of their experience, so if you’ve considered the idea of videos set to auto-play or background music to help set a tone, you may want to think again. People find it aggravating when they are searching for information only to be interrupted by a video or background music they don’t like. If you’re going to use videos, allow the visitor to decide whether they want to watch it – don’t force it on them.
Photos are a great alternative to videos in many cases, and they load far faster, which improves your site’s response time – especially on mobile devices. If your site’s visuals are well-designed and appropriately placed (and sized!) they can go a long way toward giving your visitors a pleasant, memorable experience without the need for background music or videos set to auto-play.
