Is there something that makes you trust a website you've never heard of before

I'm not talking about big brands. I mean just the sites you stumble onto with zero context, no prior knowledge, nothing familiar about them at all.

When you land there and within a few seconds you've already made some kind of judgment call. Is this place legit? Would I actually give them my card number?

I find myself doing this a lot and I can't always explain why I decide one way or the other. Sometimes it's literally just seeing trust badges. Sometimes the design just feels like someone put real effort in. Sometimes it loads fast and I can find what I need quickly and that alone is enough.

Other times something feels slightly off and I'm gone before I can even name what it was.

Is there one thing that consistently does it for you or is it more of a gut feeling that adds up from a bunch of small things at once?
