Microsoft Ends Bing Promotion Early After Hitting Cashback Limit
There is no denying that Bing's Double Cashback promotion served up some great deals. But apparently they were so good that Microsoft had to end the deal a full four days early — and even earlier for some.
Context & Ripple Effects
Bing's cashback program has been Microsoft's most visible lever for buying search share since it rolled out a 25 percent eBay Cashback rebate in November 2008, paying users a cut of their purchases to pull them through Bing rather than Google. The Double Cashback promotion was the aggressive summer-2009 escalation of that playbook.
Ending it four days ahead of schedule — and cutting some users off even sooner — because the cashback limit was hit suggests the subsidy burned through its budget faster than planned, an early test of how expensive purchased loyalty turns out to be.
First-order effects
- Shoppers who had built purchase plans around the Double Cashback window lose the rebate days before the advertised end date, and Microsoft caps its own acquisition spend at whatever limit was set.
Second-order effects
- The early cutoff hands ammunition to skeptics of cashback-driven share gains: if users came for the rebate, Microsoft now finds out how many stay once the money stops, forcing it to lean on product moves instead.
Third-order effects
- If rebates prove to rent traffic rather than build habit, the search-share contest shifts from consumer subsidies toward platform distribution — the same day's Bing SDK for iPhone and Mac points at that route — and toward proving the unit economics of search advertising itself.
The trend: Search-engine competition is moving from paid user acquisition toward platform reach and sustainable ad economics as subsidy-driven share proves fragile.
