Where are direct visitors come from?

I have started my blog for a month now and I am still building the site and uploading content. I have only 3 articles, that are human written and 1500+ words but I haven't done any SEO or backlinks.

I am building my socials to promote the blog, and maybe along the way learn about SEO.

I am looking at my Google analyics, and I don't understand how I had 100 unique visitors when I haven't promoted my blog at all. And 80% come from direct and they just scroll on my home page. ( I don't have anything in the home page, just some information about me and snippets of my blogs)

I don't understand where do these visits come from? Organic search??

Probably bots, Can be crawlers, Check how long time they spend on your site.

You can add Microsoft Bing Clarity on your website. Thus can see video activity of your visitor.

Bots hammer new sites. Usually looking for comments or contact submission.
