Seo is my worst skill, what’s yours?

So I’ve been coding for 25 years. By far my worst skill is seo.
I’ve never been able to get traffic to any of my personal websites. Like the most I ever got was 1000 in a day. But typical it’s 10 to 0.
I don’t know why I struggle so much, I’ve read up on it. Did the basics. But it so much work and I get bored because it’s not my passion.
