I wonder, is there a way with shopify to sell few products and to invest in ads for one product at a time, rather than developing a complete store. I ask this because I want to do the same like you described. But to try this with only 2-3 products (maybe not the same niche). Much like creating landing page on wordpress for songle product, and have few of these. But I want to achieve this on shopify. This way I will post and buy ads just for few products and if I see it doesnt go well I just change the products until I find good products to sell without creating the store with specific niche.

Sorry for the long question.
