I hate videos on the internet, so I started my blog (see profile) with an emphasis on text and photos. About seven years later, still going strong. Some of it gets traffic, most doesn't. Some of my absolute "shitposts" are the best performing ones (a Mazda 3 oil change post is consistently the most popular one).
I mostly write for myself. Forcing myself to finish a project so I can write about it has been good, and I know I write anything weird about it, so I can just flush state after I've finished writing and clear the mental space for it. On occasion, I'll go search for something on the web and realize that I wrote a post on it years back and had entirely forgotten that I even wrote it, which tells me that the goal of "Flush it out entirely" is working.
What's funny is that despite an absolute non-goal of optimizing for traffic, I write about weird enough stuff that I've got a lot of first page Google hits. Often enough, a friend will mention that they were searching for something and found my blog as the top hit.
About the only effort I've put into "SEO" is to make sure that my site is tight and fast (webp support, image sets, no Javascript required for function), and I'll occasionally start a "howto" post with a list of the tools required.
But I absolutely don't try to guess what people will like. I write what I want to write, and if traffic comes, great. If not, don't care either.
