I advice most clients not to even run ads for sales unless it’s part of normal business practice. If they do run sales, it’s 80%-100% through owned media channels. Then, if inventory isn’t liquidating as projected, use paid media channels.
If you must run a 24hr sales, use a strategic approach similar to this:
* before the sale, pre-sell the thing through a owned media.
* push the inventory through owned media on day of. Try to reach your goal here. If inventory still remains, nor not reach target goals…
* Use a reach/awareness vs. conversion ads to liquidate the remaining inventory (there may be opportunities to try different conversion objectives depending on the quality of your data.)
If you’re selling b/c you need an influx of cash, be careful closely monitor total spend/rev on purchases the following week or two. Depending on your type of offer (like discounts), it may affect the downstream LTV of the customer.
