Non-PRO Japanese to English Marketing Marketing / Market Research

This is from a two-part marketing strategy for a widely used household consumer product. The first part is an オープンキャンペーン where several customers win a trip to Europe. The second part involves this べた付けキャンペーン where: 上記オープンキャンペーンとリンクし尚且つ購入インセンティヴとしての機能を果たしうるグッズ. It goes on to propose various trinkets (like a face towel, flashing key chain, etc.) to attach to the product to drive sales.

Is there a known marketing term for べた付け?
I came up with:
"Sticky marketing campaign"
"In your face marketing campaign"
"Direct marketing campaign"
Any suggestions?

Thanks!
