A simple way to start is to focus on the basics first.
Start by choosing a clear niche and finding low competition keywords. Then create helpful content around those topics that actually answers what people are searching for.
After that, make sure your pages are properly optimized with good titles, headings, and fast loading speed.
Once you have some content, you can slowly work on getting a few quality backlinks and improving your existing posts over time.
Keeping things simple and consistent at the beginning usually works much better than trying too many advanced things at once.
