Well that was fast.
After pausing its U.S. Shopping campaigns at the end of April, Amazon is once again popping up in Product Listing Ad results for a number of queries. Merkle Associate Manager Robbie Schnizler first noticed the e-commerce giant’s renewed presence in Shopping results this morning, and below is a screenshot taken this afternoon.

It’s too early to quantify Amazon’s presence in auctions at this point as it takes a couple of days for data to populate in Google Auction Insights reports, which provide impression share data for AdWords advertisers and their competitors. We should have a better sense for how expansive its reentry is this weekend.
Were the past couple of weeks just part of a holdout test for Amazon to measure the incremental impact of its Shopping ads? Did Amazon get nervous after seeing a drop in orders from pausing campaigns and decide to reconsider? Was this all just a dream?
It’s anyone’s guess at this point, but for now Amazon is back in the Google Shopping game.
