Automatic placements-

A term used in AdWords reporting to reflect the webpages, videos, and apps on the Display Network where your ads show automatically based on the targeting you've selected. automatic placements are the result of placing your ad based on your other targeting methods, like keywords or topics.

Here's how automatic placements work:

If you use a “Display Network only" or "Search Network with Display Select” campaign type, and if you also use a targeting method other than managed placements in those campaigns, then your ads will have the opportunity to show on Display Network websites automatically. These appearances will be reflected as automatic placements on the statistics table of your Placements tab.

If you don't want your ads to appear in automatic placements, you can exclusively use managed placements targeting. Add managed placements to your ad group and leave the default targeting setting, “Target and bid” so your ads are eligible to show only on the websites you choose.
