I recently launched my first product on Amazon FBA with PPC and it’s doing terrible at 0 sales :(

Here’s my product listing: https://www.amazon.com/dp/B0C8VWV7RJ?ref=myi_title_dp

I’ve been trying to sell this Cold Plunge for about 3 months now.I did PPC with Automatic Targeting for 2 months with a total spend of 333 usd, 75k impressions, 0.26% CTR, 196 clicks at 1.70 usd CPC. But when checking the search terms that got these clicks, it seems as if it comes from a different product people are looking for (hot tubs). So after research, I decided to stop this campaign and do manual keyword targeting.

I then ran PPC with a manual keyword targeting for a month already. Did 20k impressions, 48 clicks, 6.5 usd CPC and 312 usd spend. I also did a negative targeting for the word ‘Hot Tub.’ All this got me to 0 conversions.

Should I throw in the towel?
