Hmm a couple of thoughts here:
This is actually super common on big sale days like Cyber Monday, even though you'd expect the opposite. What usually happens is that every single advertiser is pumping their budgets up to the max, so the competition in the ad auction goes through the roof.
This means your costs, particularly your CPMs and CPCs, will increase drastically. The algorithm is trying to find you buyers, but it's now much more expensive to reach anyone. You're likely being outbid by bigger players with massive discounts, and the algorithm struggles to find you profitable conversions in that kind of environment.
A few things to check:
- Look at your core metrics for today versus the last few days. Has your Cost Per Click shot up? If your Click-Through Rate is the same but your CPC is higher, you're just paying more to get the same person to your site because of the competition.
- Is your offer strong enough? On Cyber Monday, a standard 10% off probably won't cut it when your competitors are screaming about 50% off. Your ads might be getting clicks but when people land on your site and realize the offer isn't amazing, they leave.
- Check your on-site conversion rate. If you're getting traffic but no sales, it could be the offer, or maybe your site is loading slowly under pressure. People have zero patience on days like these and will abandon their cart if there's any friction. It's a tough day to advertise if you're not a big brand with a massive, market-beating offer.
Hope this helps!
