Don't like the ad, not enough models in lingerie.
But nowadays the only "target" for Christmas is kids, speaking to well everyone, we all get a bit sick of Christmas starting in October and I think it takes away from the excitement a bit.
As for specific industries based on Christmas marketing. My advice would be run solid ad campaigns, don't try and target broad keywords or get into competition with any big brands, as your budgets will just be irrelevant to them. Target the low hanging fruit for longer tail keywords. Also go social and go early, I know I said its really annoying that Christmas now starts in October, but as a result you have to start earlier.
Ecommerce sites themselves I would recommend looking into groupon/coupon style sites, but more important in a way would be places like: WOOT.com, http://www.iwantoneofthose.com/ and even amazon and ebay to an extent, just to get your product out there selling. Obviously look into deals and discounts.
Just my thoughts... Don't think SEO sells very well over the holiday period, although we get a nice little spike in January
