I don't know what lift tests are. It should be easy enough to devise a tool for measuring incremental ROAS under the following assumptions: a) all purchases happen online; b) I have a complete history of ad impressions and ad clicks for each user who made a purchase As you said yourself, b) breaks down for multiple platforms. It also breaks down if users have disabled tracking.

Lift tests are these things: https://www.facebook.com/business/m/one-sheeters/conversion-lift https://www.facebook.com/business/m/one-sheeters/conversion-... They are essentially what one needs to measure incremental ROAS of one's advertising. Now, there are obvious caveats (online, tracking etc) but they're much much better than what's available for other platforms.
