I write for myself. I don't track, I don't care if people read my blog.
I do mention my blog on my resume together with code repositories. It is some kind of portfolio, and it is a good learning experience for me.
I don't think that it is worth "building a brand", unless you want to specialize in building brands. It's not like someone at Google will ever read your blog and offer you a job; if you want to work at Google, learn how to pass their interview process. If you want to be visible on social media, probably you need to follow a ton of people, engage with them, produce a lot of content and the kind of content that people like or repost. This has nothing to do with a personal blog, though.
Another thing is that if you find it worth blogging about, it's probably niche in the first place. If it's common knowledge, it's probably already on Wikipedia, or StackOverflow, or now some LLM (and if you wait long enough, your blog will be part of the LLM, whether you want it or not).
I see it like FOSS: if you do it with the hope that many people will use it, then I think it's a bad idea. Because you work for free and people will never be happy. If you do it for yourself, it's great!

My blog literally had that effect from Google, many years ago -- although obviously I still had to go through the interview process. And my blog definitely helped me land my past and current jobs as recently as 2 years ago.
