What is Ads.txt and how do I install it?

Ads.txt helps the buyers of the ad placements to identify the resellers or other authorized operators of the site’s ad inventory. The Ads abbreviation, in this context, comes from Authorized digital seller.

Improve Media recommends each publisher to maintain their ads.txt files on their site in the following format:
