FB Ad has HIGH engagement, but NO SALES. How do you scale?

Hello everyone, been a lurker for a few months now. Cant Thank you all enough for your contribution to help others. I have been on my make money online journey for about 6 months now and have learned tons!

Now i am starting on E-commerce for its simplicity to understand.

So i have an item i'm promoting and one of my ad sets is having great engagement! I have a bunch of people commenting yes i do want to buy! So i duplicated the ad set with a link now.

Both ads have been up for about 2-4 days

Now my problem is that no one yet has bought. I have sent a message with purchase link and nothing so far either. So i'm not sure if i should create a wc ad, scale the ppe ad, or what since i have no purchases yet. My webpage was optimized for conversions so i do not think is that.

I know i am very close to finding the winning ad but how can i bridge from high engagement to purchase.

Then from there what would be the next step on how you scale your camps.

Thank You for your contribution warriors!
