Ads running but no conversions?
Maybe your campaign isn't the issue. it's your PDP who is creating the problem for you.

We often place a lot of importance on targeting, bids and placements but we forget that every click leads to a PDP and that shopper will exit a page if it fails to build credibility or give answers to your problem.

After managing so many accounts, this is what I have learned

1. People will scroll away from your listing images if they don't convey a message.
2. Your bullet points won't scroll down if they don't address issues.
If your reviews and A+ content don’t add confidence, the shopper will not add it in their cart.
3. If your pricing is too high without adding much values, you can’t grow no matter how much you spend on your campaigns.

We all know, Ads drive traffic but its Your PDP who always closes the deal.
Before increasing your ad spend, start working on your PDP and see an improvement in your CVR.
