Put the kibosh on these practices.
Don’t use pop-ups that require visitors to register before they can see content. You need to work for it a little bit before your visitors will hand over their details, otherwise you will scare them off. Give visitors a taste of what you’re offering before asking them to sign up for anything.
IMAGE SLIDERS / CAROUSELS
Users become frustrated when they can’t control what they’re looking at. Imagine that you are watching tv with a friend. She has the remote and every time a new channel loads up and you try to figure out what’s playing, she changes the channel on you. Annoying, right?
In addition to being annoying, carousels add bloat to a website. These rotating banners typically load all of the images to be displayed in the slider on the initial page load, therefore if your slider is 1200px by 400px, and you have four images in the rotation, you are loading four huge images on that page load. This brings up our next potential issue…
A recent study conducted by Brand Perfect revealed that 67 percent of those surveyed cited a slow-running website as their primary reason for abandoning an online purchase. It’s imperative that you optimize your site for performance at all times. You only have a few seconds to capture someone’s attention. If the user is spending those few precious seconds waiting for the page to load, it’s doubtful they will stick around for more – it’s imperative that your site is optimized for performance.
In 2012 the average attention span declined to 8 seconds (from 12 seconds just two years prior). Clocking in at a leisurely 9 seconds, goldfish now have a greater attention span than humans. [source: www.statisticbrain.com]
If a user lands on your site and they aren’t sure what to do, it’s likely they’ll leave your site and instead visit your competitors site – where they can easily find what they’re looking for.
Your website greatly contributes to how your brand is perceived – its design is no place to slack. If your site looks like it was put together by an amateur, then visitors will associate your business with an amateur level of quality.
NO MOBILE SITE
If your site’s design isn’t optimized for mobile then your company is missing out on 25% of internet users in the U.S. – users who access the internet only from their phones. Additionally, mobile sales have already overtaken desktop sales, and mobile internet usage was predicted to overtake desktop internet usage in 2014 (there’s not yet word as to whether or not it has succeeded).
No sound effects or music should ever play against the user’s will. When a website sound-rapes its visitors, the visitors become annoyed and leave the site.
