manage campaign to increase E-Commerce sales

Hi,
i have google shopping already working but don't make sales from ads only from organic serach. can you help me get sales?
from the info i got untill now its look like:
total % conversion rate is very low (%0.6), and cost per conversion is very expensivethat's because we have only Google Shopping campaigns.
so only this, very small % of visitors are buying immediately, others just are closing your website and never comeback.
for that you need to have additional campaigns which helping exactly to sell your products.Google/Youtube/Facebook/Instagram Ads Retargeting Campaigns.
