WordWatch & DataFeedWatch

They are both web applications for companies that advertise on Google:

WordWatch = Automated Bid Management. Advertisers bid on keywords. The bid is a maximum cost per click that they will be willing to pay. These bids have to be monitored and modified constantly. WordWatch does that automatically (by deploying algorithms instead of a human) and gets its customers more clicks for less cost.

DataFeedWatch = Data Feed Optimization. Web shops that want to advertise their products on Google Shopping must export a data feed from their eCommerce platform to Google. However, the feed often needs to be modified to meet Google’s requirements en to advertise more effectively. DataFeedWatch is a tool for advertisers to make those modifications to their data feed.
