With 10-30 visits per day and 1 conversion, it is typically not a traffic volume problem but rather a product page intent/clarity problem. First, look at where the traffic is coming from. If the majority of traffic is coming from social or general users, these visitors may just be curious but not buyers. That can be enough to keep conversion low.
Then, go through your best- selling product pages. As a general rule the first image, headline and price on each page should immediately convey why it’s worth the time of your customers. Include your trust factors like delivery time, returns, and reviews in the top fold.
And make the navigation simple so users can get to a product in two clicks, three, at most.
