Not sure about this one - my slightly terrible portfolio website that i'm in the process of completely revamping (bemben.co.uk) managed to mog simon wilsons webblog (https://simonwillison.net/) - which is a far better website in all aspects!
Maybe introduce some additional stats like load times, content analysis etc - and tweak the prompt slightly - just because a website looks slightly newer, doesn't mean it's better at all!
