Why am I getting 600+ visits but no sales on my website?

Hi, thanks for the advice.

When you say change colour, what colour do you recommend? A white/grey and will that make people more likely to buy? Also I will try to add a hero section soon but for now I’ve put a slide show at the top. And when you say “other 2-3” what do you mean by that? And if you have any other recommendations let me know please.

thank you!
