Thank you so much for your question. I would be interested to hear how you went about your Facebook ads and seeing if there is potentially a different approach you could try. I would recommend building up your social media accounts with followers to gain social proof of your site so people trust you. That in itself will give you more traffic and potential sales. If you would like I have some resources on how to grow your accounts naturally which I would be more than happy to send through to you if you’d like!
Another option is identifying some influencers that could promote your products! This would gain you more followers but also make your product more well known!
