Lots of traffic but no sale, no add to cart

Having the same issue, lots of traffic from 5 adverts running direct to sunglasses and Bag Collections, had 200 visits today. One of which is the flagship D&G Collection. Been using LuckyOrange to monitor which is a god send, because at least you can see whats happening. Having customer pauses in interactivity in the playback videos so gather they maybe checking prices against other sites. But I have done the same and know that my prices are cheaper if not the same. My store has only been up and running for 5 days but I though tI would get a 1 sale at least. I have all the socials and am regularly posting but to no prevail. So frustrated!
