During Black Friday, I’ve noticed many retailers, including myself, wasting substantial advertising budgets on Google Shopping ads. The main issue arises when these ads are still running for products that have already sold out, clearly demonstrating a pressing need for real-time stock management.
As we all know, Black Friday marks the peak of the retail season. However, it’s disheartening to find that so many brands, myself included, end up losing money on Google Shopping ads for items no longer available in inventory.
The problem: The ads continue to run even after items are out of stock, incurring cost-per-click charges with no possibility of conversion. Through a comprehensive study by ShoppingIQ involving 500 global retailers, it was revealed that a staggering 97% kept paying for clicks on items no longer in stock, sometimes persisting for 24–48 hours.
Why I care. Out-of-stock ads are not just a financial drain; they also skew campaign performance and disrupt algorithmic learning. When conversion rates plummet for unavailable products, it damages rankings, reduces ROI, and hampers future bidding strategies.
Example: Take Argos, for instance; they reportedly advertised items that were out of stock during Black Friday, leading to frustrated customers and depleted ad budgets.
Stock update refresh rates:
- ~24 hours: 90% of retailers
- 6–23 hours: 5%
- 48 hours: 2%
- Other: 3%
Retailers’ response: Some companies, such as Mamas & Papas, have started leveraging ShoppingIQ’s real-time stock technology. This helps them focus ads solely on products that are actually available. Samantha Dabek, Senior Digital Marketing Manager, shares that they have managed to cut unnecessary costs and ensure advertising is targeted toward in-stock products.
The bigger picture: Google Shopping commands around 75% of US retail search spending. However, the default settings let out-of-stock ads run unchecked. ShoppingIQ strongly advocates for retailers to seek more transparency and control from Google to prevent wasted spending.
Bottom line: For those of us running high-stakes campaigns during Black Friday and other peak times, real-time stock management is essential. Otherwise, each wasted click represents money lost.
