The UPvotes are coming in through auto-vote bots. If you have a post that only has 10 views but 15 UPvotes then it is that some of the people UPvoting are using a bot. This means they have it set up to automatically UPvote certain people's posts. They either know this person is writing quality content, want to be supportive and do not want to miss a post.

I have found the best way to become visible honestly was to join Discord groups and communities and be active. I belong to about a dozen Discord groups, am active daily in about six of them and comment, post promote.

Also... one thing I notice... if you comment on someone's post and they comment back, they are more likely to go to your page and perhaps comment on one of your posts. The more you do this, the more traffic comes to your page and posts. People are here for interaction so you have to use this to your advantage.
