Startups face many challenges in their early days before becoming profitable. Getting their website is the first step and then their learning starts. Only by trial and error they learn every aspect and master the art of establishing a successful e-Commerce website.
Unlike a physical shop where anyone can monitor the visitors, on a website though, you need to use various tools to measure the footfalls, gather info on what the visitor did or where he moved etc. then invite the users to connect and provide feedback. Only when confident the visitor makes a purchase and many a time spreads the word.
