Made-for-arbitrage (MFA)

The label "MFA" is used two ways in ad tech. In display advertising it usually means "made for advertising": pages crammed with banners and fed by cheap paid traffic. In search arbitrage it means a page whose real purpose is to host a search feed, with a thin article wrapped around the related-search unit. See ad arbitrage and search arbitrage.

The term is a criticism, not a legal category. Critics say such pages waste advertiser money and give users nothing. Defenders point out that a useful page funded by ads and promoted with paid traffic is an ordinary publishing model. The dividing line is value to the visitor.

Google's rules draw the same line. The AdSense Program policies bar ads on pages designed primarily to display advertisements, and the RSOC guidance requires content with sufficient standalone value, rejecting pages with little content or more ads than content. Pages that fail are exposed to violations and to advertisers using placement exclusions.

Increasingly, AI-generated content makes thin pages cheap to produce, which is one reason enforcement has tightened.

Think of it like this

It is the difference between a magazine that carries adverts and a leaflet that is nothing but adverts with a paragraph of text to make it look like a magazine.
