I often get asked if I'm happy with my websites and how often I update them.
The truth is that I'll never be 100% happy with websites, they can always be improved, as can ANY website. I update my websites at least once a week, often just small tweaks and experiments.
I'd encourage everyone who looks after a website to frequent try out new things on their site. It could be rewording a paragraph or product, changing a photo, rearranging the order of blocks.
I also have the luxury of experimenting with my business model, which means updating my websites accordingly. A word of caution (note to self): be careful not to contradict anything said previously or advertised. A confusing website lacks effectiveness.
