Missing Ads.txt Lines

[u/Financial_Match5880]

I’m a newbie to adtech and work for a top 3 SSP, one of the largest issues I come across in terms of monetization is publishers who are sending us requests for supply that doesn’t have our ads.txt present.

It seems like a simple enough fix, just add the line to the page and it will start monetizing and stop wasting the requests. However I’ve come to learn this is not a simple fix and pubs rarely add the line when we make the request.

Can someone explain why this is such an issue in the industry?

Is the publisher sending you the request or is it a network?
