This is no way a criticism of anyone here offering advice, as some of this is really helpful. It’s just a general observation that applies to guidance, growth strategies, apps, etc., for startups and those new to eCommerce.
As one of those myself, it’s frustrating when the reviews app, Judge.me, for example, tells you how amazing it will be for your business to show the reviews on this page and that page, show trust badges, and so on. Or how using tools to glean usage stats and habits from your customers will help shape your website. But none of that applies when you have no or low sales. In fact very little applies or is of any direct use when you have no/low sales because you have nothing to work with and no data. All that’s really important in the early stages is making sure your website provides no barriers whatsoever to customers buying (exactly as some of the advice given here is suggesting) and marketing, marketing, marketing.
It’s a numbers game, and in the early days it’s painfully painful, trying to persuade people who know nothing about you that your products are great and that they can trust you. It’s also a chicken and egg situation - how do you get people to trust you enough to buy from you when you have no reviews telling people they can trust you. But you need sales in order to generate the reviews.
My advice is take and implement every bit of advice that is relevant to your situation to make your website the best it can be - something you would want to buy from. That means painstaking attention to detail, acccuracy, honesty, being informative, overly helpful, and fair. It’s a bit of a sweeping statement, but people buy based on value, not price, so if your products look like they offer value, the price is relatively unimportant. And I’m only saying this as a driver to make sure your products look better and website delivers more than your competitiors.
Ask lots of people to critique and feedback on your website (don’t take it personally!) and the entire customer journey and experience (they are very different) - and ignore everything else for now. Then get back to marketing.
And yes, it’s tempting to buy your audience. Yes, it’s tempting to fake reviews or testimonials, but a single trip-up with the latter especially could crush everything you’ve built in one go.
I wish you the absolute very best of luck - you, me, and everyone else trying to build their dream and change their lives for the better.
