I generally agree with these points. We ended up with an interstitial the same way I hope most everyone else did: we A&#x2F;B tested it, and the results were clearly positive on engagement and purchase.<p>We could choose to drop the interstitial as a matter of principal or on the assumption that the difficult-to-quantify long-term benefit will pay off later, but we&#x27;d have to make that decision not in the absence of data, but actually in opposition to the data.<p>Or let Google make the decision for us...
