How seriously do you take relationship advice from inexperienced friends?

People who are in relationships, or have been, how seriously do you take advice from relationship advice from friends with no dating experience?

For context: (You can js ignore my story but and answer the main question btw) I have no actual dating or sexual experience myself, and it's not something I hide or am ashamed about. It's not that I'm uninterested, I've just never really pursued possible relationships for whatever reason, and I'm relatively content with just having my close friendships. I'm also def the honest 'say-it-how-it-is' type of friend, and while I try my best to be polite when it come to friends I know are sensitive, I rarely sugarcoat my words with close friends, and really prioritise open communication.

In the past, and present, I've had friends come to me to talk about their troubles in their relationship, or I hear about friends and their shirty partners, and I always do my best to advise them by seeing things in their perspectives. And while I'm not expecting them to always take my advice and act on it, I wonder how much they really take it to heart. Especially when they don't seem to act on my advice, only for them to break up with that partner a couple months later because said partner's behaviour had only gotten worse. OR when I advised that the couple go on a break, or at least communicate about how they feel, only for one of them to cheat on the other. (Both ppl in that couple were my friends)
