I am running campaigns on Google Adwords and I hear that people most likely to search about the store or look for reviews about the store they intent to purchase from and new to them. So, I am wondering how I can make sure that I met their trust needs while I dont reviews or such as BBB accredentials. I sell fine jewelry.
At first you should add Trust Seals if you haven't already. The next thing to do is get a few Instagram influencers to promote your product. User Generated Content (UGC) is a great trust builder. You should generate UGC from your retargeting campaigns as well. Also if I may ask why are you not running Facebook ads to the store. Also are you running Search network ads or Google Shoppiing ads right now?
