Bing is sharing some Mother’s Day search insights to help advertisers better plan for the holiday, which will be here in just over three weeks, meaning shopping time is from now and until then.

According to Microsoft’s search team, Mother’s Day mobile searches grew by more than a third from 2014 to 2015. Mother’s Day searches begin in April, but users are most active seven days before the holiday.

The top searches, according to Bing, are for generic “gifts” (43%), flowers (31%), jewelry (13%), cards (7%), and chocolate or other foods (6%).

Product ads via Bing Shopping campaigns saw “across the board increases” the week of Mothers Day with jewelry showing the biggest percentage gains.

“Insights gained from Bing Ads give advertisers the tools they need to decide when to increase the intensity of their Mother’s Day campaigns and across which devices,” said Bing Global Marketing Manager Frances Donegan-Ryan. “This helps ensure to ensure their campaigns are having the most impact while delivering the best value.”

“Data from Bing Ads also help shed light on some of the differences between Bing and Google audiences ­– including the fact Bing users are more likely to have spent money on jewelry, greeting cards or flowers in the last six months,” a spokesperson for Bing tells us. “This data is essential for advertisers looking to optimize their approach to a Bing Ads campaign over a one-size-fits-all approach.”
