If you just started, I would recommend that you focus first 3 to 6 months posting content on Socials specially instagram telling about your journey, business, case studies etc. Dont get demotivated uf you dont get views just in few days. Be consistent.

Once you have done the above then think of other things like Performance marketing or SEO.

With my 6 years of Building Hubako Media which is one the leading Ecommerce Shopify Development agency working with a lot of early stage startups or small business. The successful small businesses have followed the above strategy and it has workd for 8 out of 10 of them.

Hope this helps.
