100 Website Fails Checklist

I was scrolling Threads last week when I came across a post asking a simple question:
What do you actually hate about websites?
The replies went OFF.
 
I collated everything, cut the duplicates, sectioned them and added a few of my own (as someone who builds these things for a living). This led to a checklist of 100 reasons why your website is failing.
 
From pop-ups to pixelated images, here are 100, universal mistakes that are costing businesses real money every single day. *confession I had 3 out of the 100 I found.
 
Some of these are quick fixes. Some need a proper look at your site strategy. Either way, if more than 10 of these are you right now, that's worth a conversation. But in the interim, enjoy seeing where you're going wrong.
