I've seen this mistake alot of times whenever I analyze websites:

Let's take this example - you want to build a website for a brand that sells food and you're asking your developer to take inspirations and ideas from a brand that offers branding services 🙃
What do you think will be end result? Your website won't resonate with your audience!

One of the beautiful things about being a web developer is that you can't visit a website and not make proper analysis 😅... And I also have this sickness with designs 🤣
But it is one of the things that keep me in check and make me stand out!

Your website should and must reflect what you do if you want results! As much as that e-commerce website has amazing features, you would not want to build your portfolio website like you're selling food!

Right message = Right audience🥂
