It seems like uncomfortable timing for this announcement, but Pinterest has today unveiled a new, 'Dynamic Creative' ad process which will enable advertisers to automate the ad creation and targeting process for their campaigns based on individual user behavior. The process essentially responds to how users interact in the app - if a user is searching for 'decorative lights' for example, and they narrow their search for specific items, the system will then show ads for items from your uploaded catalog which best match the users' stated interest. As explained by Pinterest: "Advertisers can now generate multiple versions of new Pins from uploaded assets or a product feed where they can automatically import product data (price, location, availability, etc.). Parts of the Pins will dynamically display creative elements like product images, copy, pricing, etc. which will only be shown to the advertiser’s assigned audiences."
