Remember, if you are interested in some topic, then you are clearly not alone, which means there are other communities or sites on your or related topics. Find them, start communicating with users within the community, perhaps you will help them and they will become your clients or audience of your blog, the main thing is you can find new ideas for your site.
For example, if you are repairing washing machines, find a forum where they ask questions about certain brands or machines in general; I myself recently studied the forums about the features of my new machine, and they helped me, which means that if I had a problem, I already I know where to turn. By communicating directly with people, show them your professionalism, you will definitely promote your website, expand your client base and the level of trust in you if you are good at this. If you wish, you can organize a forum or blog with discussion on your website, as one of our clients did - a forum for kindergarten directors. It would seem such a trifle, but it turns out there are simply no such forums, and he became the first.
